<h2><a name="General_overview"></a>General overview</h2>
<p>
This document describes how to build a Ghostscript executable from source
code. There are four major steps to building Ghostscript:
<ol>
<li>Acquire the compressed archive files of source code for Ghostscript and
the required third-party libraries.
<li>Unpack the archive files into the Ghostscript directory and correctly
named subdirectories.
<li>Prepare the makefiles, including specific changes for your operating
environment and your choice of configuration options.
<li>Invoke "<b><tt>make</tt></b>" to build the software.
</ol>
<p>
The remainder of this document describes each of these steps in detail.
Note that some of this process is platform-dependent. After building
Ghostscript you must then install it; for that, see the
<a href="Install.htm">installation instructions</a>.
<hr>
<h2><a name="Acquiring"></a>How to acquire the source code</h2>
<p>
Building Ghostscript requires the Ghostscript source code itself, and also
the source code for some third-party libraries that Ghostscript uses.
<h3><a name="Ghostscript_source"></a>Ghostscript source code</h3>
<p><a name="Authoritative_distribution_site"></a>
There are two kinds of Ghostscript distributions available, called "AFPL
Ghostscript" and "GNU Ghostscript"; the distinction between them is
explained in the <a href="Commprod.htm">conditions for distributing
Ghostscript</a>. The authoritative distribution site for AFPL
Ghostscript is
<blockquote>
<a href="ftp://mirror.cs.wisc.edu/pub/mirrors/ghost/APFL/"
class="offsite">ftp://mirror.cs.wisc.edu/pub/mirrors/ghost/APFL/</a>gs###
</blockquote>
<p>
where "###" is the unpunctuated version number. GNU Ghostscript should be
available on all GNU sites, such as
<blockquote>
<a href="ftp://ftp.gnu.org/pub/gnu/"
class="offsite">ftp://ftp.gnu.org/pub/gnu/</a>
</blockquote>
<p>
Ghostscript source code is packaged in two different formats:
gzip-compressed tar files (*<b><tt>.tar.gz</tt></b>) and zip files
(*<b><tt>.zip</tt></b>). For all versions there are gzip-compressed tar
files:
<blockquote>
<b><tt>ghostscript-</tt></b>#.##<b><tt>.tar.gz</tt></b><br>
<b><tt>ghostscript-fonts-std-</tt></b>#.##<b><tt>.tar.gz</tt></b><br>
<b><tt>ghostscript-fonts-other-</tt></b>#.##<b><tt>.tar.gz</tt></b>
</blockquote>
<p>For recent versions of AFPL Ghostscript -- <b><em>not</em></b> GNU
Ghostscript -- there are also zip files (each zipped file fits onto a
single 1.44MB diskette):
<blockquote>
<b><tt>gs</tt></b>###<b><tt>fn</tt></b>*<b><tt>.zip</tt></b><br>
<b><tt>gs</tt></b>###<b><tt>sr</tt></b>*<b><tt>.zip</tt></b>
</blockquote>
<p>
("#.##" and "###" are version numbers in punctuated and unpunctuated form.)
Software to decompress and extract both formats is available for almost
every platform for which Ghostscript is available -- including Unix, DOS,
MS Windows, and VMS -- so you can choose the format most convenient for
you; but it's up to you to locate that software. See the section on <a
href="#Unpack">unpacking the source code</a>.
<h3><a name="Third-party_libraries"></a>Third-party library source code</h3>
<p>
To build Ghostscript you need the source code for the <a
href="http://www.ijg.org/">Independent JPEG Group</a> (IJG) library, the
<a href="http://www.libpng.org/pub/png/">Portable Network Graphics</a>
(PNG)
library, and the <a
href="http://www.info-zip.org/pub/infozip/zlib/">zlib</a>
compression and decompression library. Here are authoritative distribution
points for these libraries, where as elsewhere, "#" is used for version
numbers. The JPEG source code is quite stable, so the reference
here includes the latest version number. The zlib references are
version-independent and should always provide the latest version.

<p>
On DOS or MS Windows one ordinarily uses the zip file kits, in other
environments the compressed tar files, but this is simply a matter of
convenience, since for the same version of the software the compressed tar
file has the same contents as the zip file. Note that each of these
libraries has <b><em>its own version number</em></b> that has
<b><em>nothing to do with Ghostscript's version number</em></b>; you should
get the highest numbered version. (If you encounter difficulties in the
build process you might have to use a lower-numbered version, but don't
worry about this yet.) If you're running Linux, you might check whether
these libraries are already available in source form on your system, since
many Linux distributors include them; but we advise you to get the highest
version from the Net if you can.
<p>
Although the zip archives of an old version of the PNG library may not be
named <b><tt>lpng</tt></b>###<b><tt>.zip</tt></b>, we refer to it as
<b><tt>lpng</tt></b>###<b><tt>.zip</tt></b>.
<hr>
<h2><a name="Unpack"></a>How to unpack the source code</h2>
<p>
Unfortunately there are no generally accepted standards for how to package
source code into archives, so the instructions for unpacking Ghostscript are
longer than they should be. We begin with a brief explanation of how to
extract the two kinds of archive files.
<h3><a name="Tarfiles"></a>How to unpack compressed tar files generally</h3>
<p>
Tar (<b><tt>.tar</tt></b>) files are the <em>de facto</em> standard for
archiving files on Unix (every Unix system has the <b><tt>tar</tt></b>
program), and programs to extract their contents are also widely available
for DOS, MS Windows, and VMS. To economize on space and downloading time,
Ghostscript's tar files are compressed with GNU <b><tt>gzip</tt></b>, which
adds the suffix "<b><tt>.gz</tt></b>" to the file name, giving
"<b><tt>.tar.gz</tt></b>".
<p>
To unpack a compressed tar file <b><tt>MyArchive.tar.gz</tt></b> you
must both decompress it and extract the contents. You can do this in two
steps, one to decompress the file and another to unpack it:
<blockquote>
<b><tt>gzip -d MyArchive.tar.gz</tt></b>
<br><b><tt>tar -xf MyArchive.tar</tt></b>
</blockquote>
<p>
or in a pipeline:
<blockquote>
<b><tt>gzip -d -c MyArchive.tar.gz | tar -xf -</tt></b>
</blockquote>
<p>
or, if you have a program like GNU <b><tt>tar</tt></b> that can handle
compressed tar files, with a single command:
<blockquote>
<b><tt>tar -zxf MyArchive.tar.gz</tt></b>
</blockquote>
<p>
The <b><tt>tar</tt></b> program automatically preserves directory structure
in extracting files. The Ghostscript source archive puts all files under a
directory <b><tt>gs</tt></b>#.##, so using <b><tt>tar</tt></b> to unpack a
compressed archive should always properly create that directory, which we
will call the "gs directory". Make sure you're positioned in the
<b><em>parent</em></b> of the gs directory <b><em>before</em></b> unpacking
the files. If a subdirectory doesn't already exist, <b><tt>tar</tt></b>
creates it.
<p>
Some other programs -- under MS Windows, for instance -- can also unpack
compressed tar files, but they may not automatically preserve directory
structure nor even extract files into the current directory. If you use
one of these, you must
<ul>
<li>set the program's options to "Use folder names" or the equivalent, and
<li>check that it is extracting files into the right place.
</ul>
<h3><a name="Zipfiles"></a>How to unpack zip files generally</h3>
<p>
Zip files are the <em>de facto</em> standard for archiving files on DOS and
MS Windows, and programs to extract their contents are widely available for
DOS, MS Windows, Unix, VMS, and other platforms. Zip files are at once an
archive format and a compressed format, so an unzipping program
decompresses and extracts archived files as a single step.
<p>
One common 16-bit DOS program is <b><tt>pkunzip</tt></b>, which comes in
the <b><tt>pkzip</tt></b> package. If you use this, you should ensure that
you have at least version 2.04g, because with its <b><tt>-d</tt></b>
switch, that version of <b><tt>pkunzip</tt></b> preserves the directory
structure of archived files when extracting them; see below. Another
popular free program to unpack zip archives, available for DOS and MS
Windows (16-bit and 32-bit), Unix, VMS, and other platforms, is InfoZIP
<b><tt>unzip</tt></b>:
<blockquote>
<a href="http://www.info-zip.org/pub/infozip/UnZip.html"
class="offsite">http://www.info-zip.org/pub/infozip/UnZip.html</a>
</blockquote>
<p>
Unlike <b><tt>pkunzip</tt></b>, InfoZIP <b><tt>unzip</tt></b> automatically
preserves the directory structure of extracted files. So if you have a zip
archive <b><tt>MyArchive.zip</tt></b>:
<blockquote><table cellpadding=0 cellspacing=0>
<tr><th colspan=3 bgcolor="#CCCC00"><hr><font size="+1">Extracting zipped files</font><hr>
<tr valign=bottom>
<th align=left>Command
<td>
<th align=left>Preserves directory structure
<tr> <td colspan=3><hr>
<tr valign=top> <td><b><tt>pkunzip MyArchive.zip</tt></b>
<td>
<td>Does <b><em>NOT</em></b>
<tr valign=top> <td><b><tt>pkunzip -d MyArchive.zip</tt></b>
<td>
<td><b><em>DOES</em></b> (note the <b><tt>-d</tt></b> switch)
<tr valign=top> <td><b><tt>unzip MyArchive.zip</tt></b>
<td>
<td><b><em>DOES</em></b>
</table></blockquote>
<p>
As with the compressed tar files, make sure you're positioned in the
<b><em>parent</em></b> of the gs directory <b><em>before</em></b> unpacking
the files. If a subdirectory doesn't already exist, <b><tt>zip</tt></b> or
<b><tt>pkunzip -d</tt></b> creates it.
<h3><a name="Unpack_Ghostscript"></a>How to unpack Ghostscript itself</h3>
<p>
At this point you have <a href="#Acquiring">acquired all the source code</a>
and are ready to unpack it according to the preceding guidelines for <a
href="#Tarfiles">tar files</a> or <a href="#Zipfiles">zip files</a>. To
unpack the Ghostscript source, make the <b><em>parent</em></b> of the (new)
gs directory the current directory.
<blockquote><table cellpadding=0 cellspacing=0>
<tr> <th align=left valign=top>2-step:
<td>
<td><b><tt>gzip -d ghostscript-</tt></b>#.##<b><tt>.tar.gz</tt></b><br><b><tt>tar -xf ghostscript-</tt></b>#.##<b><tt>.tar</tt></b>
<tr><td>
<tr> <th align=left valign=top>Pipe:
<td>
<td><b><tt>gzip -d -c ghostscript-</tt></b>#.##<b><tt>.tar.gz | tar -xf -</tt></b>

<tr><td>
<tr> <th align=left valign=top><tt>unzip</tt>:
<td>
<td><b><tt>unzip gs</tt></b>###<b><tt>sr*.zip</tt></b>
</table></blockquote>
<p>
All the Ghostscript source files are now in subdirectories of the gs
directory.
<blockquote><table cellpadding=0 cellspacing=0>

<h3><a name="Unpack_libraries"></a>How to unpack the third-party libraries</h3>
<p>
The Ghostscript makefiles expect to find the JPEG, PNG, and zlib source code
in specific subdirectories of the <b><tt>gs</tt></b> directory, and this
means you must pay careful attention to unpacking the source code for these
packages. Use the same method for all of them, no matter how they're
packaged:
<ol>
<li>Make the gs directory current.
<li>Unpack the archive file, creating a subdirectory (which will include a
version number).
<li>Whatever the subdirectory's original name, rename it to the versionless
name shown just below.
</ol>
<p>
If you're uncertain how to unpack an archive, review the sections on <a
href="#Tarfiles">compressed tar files</a> and <a href="#Zipfiles">zip
files</a>.

<h2><a name="Makefile_overview"></a>How to prepare the makefiles</h2>
<p>
The Ghostscript makefiles are very large and complex in order to deal with
the diverse requirements of all the different systems where they may be
used. Fortunately, the only makefiles you're likely to want to change are
relatively small ones containing platform-specific information.

<p>
Since these files change from one Ghostscript version to another, sometimes
substantially, and since they all include documentation for the various
options, here we don't duplicate most of that documentation: we recommend
strongly that you review the entire makefile specific for your operating
system and compiler before building Ghostscript.
<h3><a name="Preparing_makefiles"></a>Changes for your environment</h3>
<p>
You must edit the platform-specific makefile to change any of these:
<ul>
<li>The name of the makefile itself (<b><tt>MAKEFILE</tt></b> macro)
<li>The locations to install Ghostscript files (<b><tt>prefix</tt></b> etc.)
<li>The default search paths for the initialization and font files
(<b><tt>GS_LIB_DEFAULT</tt></b> macro)
<li>The debugging options (<b><tt>DEBUG</tt></b> and <b><tt>TDEBUG</tt></b>
macros)
<li>Which optional features to include (<b><tt>FEATURE_DEVS</tt></b>)
<li>Which device drivers to include (<b><tt>DEVICE_DEVS</tt></b> and
<b><tt>DEVICE_DEVS</tt></b>{<em>1--20</em>} macros)
<li>Default resolution parameters for some printer drivers
(<b><tt>devs.mak</tt></b> or <b><tt>contrib.mak</tt></b>, whichever defines
the driver)
</ul>
<p>
The <a href="#Platform-specific_makefiles">platform-specific makefiles</a>
include comments describing all these except the
<b><tt>DEVICE_DEVS</tt></b> options. These are described in
<b><tt>devs.mak</tt></b> and <b><tt>contrib.mak</tt></b>, even though the
file that must be edited to select them is the <a
href="#Platform-specific_makefiles">platform-specific makefile</a>. Check
also the <b><tt>JVERSION</tt></b> and <b><tt>PVERSION</tt></b> macros in
the platform-specific makefile, and adjust them if they don't match the
JPEG and PNG library versions you're using: see <b><tt>jpeg.mak</tt></b>
and <b><tt>libpng.mak</tt></b> for more information.
<p>
Some platform-specific options are described in the sections for individual
platforms. See the "Options" section near the beginning of the relevant
makefile for more information.
<h3><a name="Features_and_devices"></a>Selecting features and devices</h3>
<p>
You may build Ghostscript with any of a variety of features and with any
subset of the available device drivers. The complete list of features is
in a comment at the beginning of <b><tt>gs.mak</tt></b>, and the complete
list of drivers in comments at the beginning of <b><tt>devs.mak</tt></b>
and <b><tt>contrib.mak</tt></b>. To find what devices a platform-specific
makefile selects to include in the executable, look in it for all lines of
the form
<blockquote>
<b><tt>FEATURE_DEVS=</tt></b><em>{list of features}</em><br>
<b><tt>DEVICE_DEVS</tt></b>*<b><tt>=</tt></b><em>{list of devices}</em>
</blockquote>
<p>
For example, if the makefile has
<blockquote><b><tt>
FEATURE_DEVS=$(PSD)level2.dev
</tt></b></blockquote>
<p>
indicating that only the PostScript Level 2 facilities should be included,
you might make it
<blockquote><b><tt>
FEATURE_DEVS=$(PSD)level2.dev $(PSD)pdf.dev
</tt></b></blockquote>
<p>
to add the ability to interpret PDF files. (In fact,
<b><tt>FEATURE_DEVS</tt></b> in the current Unix makefiles already includes
<b><tt>$(PSD)pdf.dev</tt></b>.) The Unix makefile also defines
<blockquote><b><tt>
DEVICE_DEVS=$(DD)x11.dev
</tt></b></blockquote>
<p>
indicating that the X Windows driver should be included, but since
platform-specific makefiles as distributed normally include many of the
possible features and drivers, you will probably rather remove from the
makefile the features and drivers you don't want. It does no harm to
include unneeded features and devices, but the resulting executable will be
larger than needed.
<p>
You may edit the <b><tt>FEATURE_DEVS</tt></b> line to select or omit any of
the features listed near the beginning of <b><tt>gs.mak</tt></b>, and the
<b><tt>DEVICE_DEVS</tt></b>* lines to select or omit any of the device
drivers listed near the beginning of <b><tt>devs.mak</tt></b> and
<b><tt>contrib.mak</tt></b>. The first device listed in the definition of
<b><tt>DEVICE_DEVS</tt></b> becomes the default device for this executable;
see the usage documentation for <a href="Use.htm#Output_device">how to
select an output device</a> at run time using the
<a href="Use.htm#DEVICE_switch"><b><tt>-sDEVICE=</tt></b></a> switch. If
you can't fit all the devices on a single line, you may add lines defining
<blockquote>
<b><tt>DEVICE_DEVS1=$(DD)</tt></b><em>{dev11}</em><b><tt>.dev</tt></b> ... <b><tt>$(DD)</tt></b><em>{dev1n}</em><b><tt>.dev</tt></b>
<br><b><tt>DEVICE_DEVS2=$(DD)</tt></b><em>{dev21}</em><b><tt>.dev</tt></b> ... <b><tt>$(DD)</tt></b><em>{dev2n}</em><b><tt>.dev</tt></b>
</blockquote>
<p>
etc., up to <b><tt>DEVICE_DEVS15</tt></b>. Don't use continuation lines --
on some platforms they don't work.
<p>
Note that if you want to include a driver named <em>xxx</em>, you must put
<b><tt>$(DD)</tt></b><em>xxx</em><b><tt>.dev</tt></b> in
<b><tt>DEVICE_DEVS</tt></b>*. Similarly, if you want to include a feature
related to the PostScript or PDF language interpreters (PostScript level
1 .. 3, or other language features such as the ability to read EPSF files or
TrueType font files), you must represent it as
<b><tt>$(PSD)</tt></b><em>xxx</em><b><tt>.dev</tt></b>. If you are linking
only the graphics library -- not the language interpreter(s) -- with an
application and want to include optional graphics library features such as
CIE color, you represent them as
<b><tt>$(GLD)</tt></b><em>xxx</em><b><tt>.dev</tt></b>.
<h4><a name="Precompiled_data"></a>Precompiled run-time data</h4>
<p>
Ghostscript normally reads a number of external data files at run time:
initialization files containing PostScript code, fonts, and other resources
such as halftones. By changing options in the top-level makefile for the
platform, you can cause some of these files to be compiled into the
executable: this simplifies installation, improves security, may reduce
memory requirements, and may be essential if you are planning on putting
Ghostscript into ROM.
<p>
To compile the initialization files (<b><tt>lib/gs_init.ps</tt></b>, etc.)
into the executable, change the <b><tt>0</tt></b> to a <b><tt>1</tt></b> in
the line
<blockquote><b><tt>
COMPILE_INITS=0
</tt></b></blockquote>
<p>
To compile fonts into the executable, see <a
href="Fonts.htm#Precompiling">Precompiling fonts</a>.
<p>
To compile threshold-array halftones into the executable, see the "Compiled
halftone" section of <b><tt>int.mak</tt></b> for a sample makefile fragment,
<b><tt>genht.c</tt></b> for the syntax of halftone data files, and
<b><tt>lib/ht_ccsto.ps</tt></b> for a sample data file. Note that even
though the data files use PostScript syntax, compiled halftones do not
require the PostScript interpreter and may be used with the graphics library
alone.
<h4><a name="GNU_readline"></a>GNU readline</h4>
<p>
AFPL Ghostscript does not include an interface to GNU readline. A user
contributed code for this purpose, which we spent significant time debugging
and then updating to track internal architectural changes in Ghostscript.
The contributor was willing to assign the copyright to Aladdin Enterprises
(the copyright holder of Ghostscript at the time), and to allow the code to
be distributed with the Aladdin Free Public License (AFPL) as well as the
GNU License (GPL). However, even though the GPL allows linking GPLed code
(such as the GNU readline library package) with non-GPLed code (such as all
the rest of AFPL Ghostscript) if one doesn't distribute the result, the Free
Software Foundation, creators of the GPL, have told us that in their
opinion, the GPL forbids distributing non-GPLed code that is merely
<em>intended</em> to be linked with GPLed code. We understand that FSF
takes this position in order to prevent the construction of software that is
partly GPLed and partly not GPLed, even though the text of the GPL does not
actually forbid this (it only forbids <em>distribution</em> of such
software). We think that FSF's position is legally questionable and not in
the best interest of users, but we do not have the resources to challenge
it, especially since FSF's attorney apparently supports it. Therefore, even
though we added the user-contributed interface to GNU readline in internal
Aladdin Ghostscript version 5.71 and had it working in version 5.93 (one of
the last beta versions before the 6.0 release), we removed it from the
Aladdin Ghostscript 6.0 distribution.
<p>
GNU Ghostscript distributions will include support for GNU readline. As
with other GNU Ghostscript components that are not included in AFPL
Ghostscript, the maintainers of Ghostscript will not attempt to run, link,
or even compile this code, or keep it current across changes in the rest of
Ghostscript. We will, however, welcome bug fixes or updates, and distribute
them with subsequent releases of GNU Ghostscript.
<p>
The first GNU Ghostscript distribution that will include GNU readline
support will be GNU Ghostscript 6.0, currently scheduled for release along
with AFPL Ghostscript 7.0 in the first or second quarter of 2001. Before
that time, we may return the copyright of Ghostscript's GNU readline
interface module, which the original author assigned to Aladdin Enterprises,
to the author, so that users of GNU Ghostscript will have have access to it.
However, since it requires internal changes not available in any released
GNU Ghostscript version before 6.0, any user who gets this code and links it
with Aladdin Ghostscript 6.0 will, according to FSF, be violating the intent
(though not the letter) of the GPL.
<p>
We put considerable work into making it possible for Ghostscript to use GNU
readline, including the creation and adjustment of internal software
interfaces specifically to serve this purpose. In principle, we should have
undone this work in AFPL Ghostscript, lest FSF object to it too as
intended to facilitate linking AFPL Ghostscript with GNU readline (as the
U.S. government has been said to do for code that merely provides APIs where
encryption may be added). However, we are willing to take this risk rather
than spend the time to undo the interface changes.
<p>
If you have comments or questions about this situation, please feel free to
contact the Free Software Foundation, authors of the GPL and copyright
holders of GNU readline, at <a href="mailto:gnu@gnu.org">gnu@gnu.org</a>,
and/or artofcode LLC, copyright holder of Ghostscript, at <a

<h3><a name="Makefile_setup"></a>Setting up "makefile"</h3>
<p>
After going through the steps just described to <a href="#Unpack">unpack
the

the
makefiles</a>, and unpack or create links to the <a
href="#Unpack_libraries">third party libraries</a>, as the final step in
preparing to build Ghostscript you must usually associate the name
"<b><tt>makefile</tt></b>" with the correct makefile for your environment so
the <b><tt>make</tt></b> command can find it. See the section on your
particular platform for how to do that if necessary.
<h3><a name="Invoke_make"></a>Invoking "make"</h3>

</dl>
<p>
<b><em>Note:</em></b> on most platforms some of these simple instructions don't
quite work in one way or another. Read the section on your specific
platform.
<h3><a name="Cross-compiling"></a>Cross-compiling</h3>
<p>
If you are compiling Ghostscript on machines <b>X1</b> ... <b>X</b><em>n</em> with
cross-compilers that generate code for machine <b>Y</b>, you must first
perform several extra steps on some machine <b>Z</b> (not necessarily of the
same type as either <b>X</b><em>i</em> or <b>Y</b>). First of all, choose a makefile
appropriate for <b>Z</b> and edit it to reflect the run-time options you
wish to include (<b><tt>FEATURE_DEVS</tt></b>, <b><tt>DEVICE_DEVS*</tt></b>,
and any other relevant options), just as for non-cross-compilation.
<p>
If <b>Z</b> runs Unix, perform the following steps:
<ol>
<li>On <b>Z</b>,
<blockquote>
<b><tt>make clean</tt></b><br>
<b><tt>make obj/arch.h obj/genconf obj/echogs</tt></b>
</blockquote>
<li>Edit <b><tt>obj/arch.h</tt></b> to reflect the architecture of <b>Y</b>.
<li>On <b>Z</b>,
<blockquote>
<b><tt>make CC=: CCLD=:</tt></b>
</blockquote>
<li>Copy the files <b><tt>obj/*.h</tt></b> from <b>Z</B> to the directory on
each <b>X</b><em>i</em> that will be used for compilation.
<li>Extract from the file <b><tt>obj/ldt.tr</tt></b> (on <b>Z</b>) the list
of <b><tt>.o</tt></b> files that will be linked: this gives the list of
source files that must be compiled.
<li>Do the compilations on <b>X</b><em>i</em>.
</ol>
<p>
If <b>Z</b> runs some version of Microsoft Windows with Microsoft Visual
C++, use the following steps. <em>NOTE: We have not actually tested
this.</em>
<ol>
<li>On <b>Z</b>,
<blockquote>
<b><tt>nmake clean</tt></b><br>
<b><tt>nmake obj\arch.h obj\genconf.exe obj\echogs.exe</tt></b>
</blockquote>
<li>Edit <b><tt>obj\arch.h</tt></b> to reflect the architecture of <b>Y</b>.
<li>On <b>Z</b>,
<blockquote>
<b><tt>nmake CC=rem LINK=rem</tt></b>
</blockquote>
<li>Copy the files <b><tt>obj\*.h</tt></b> from <b>Z</B> to the directory on
each <b>X</b><em>i</em> that will be used for compilation.
<li>Extract from the file <b><tt>obj\ldt.tr</tt></b> (on <b>Z</b>) the list
of <b><tt>.obj</tt></b> files that will be linked: this gives the list of
source files that must be compiled.
<li>Do the compilations on <b>X</b><em>i</em>.

<h2><a name="PC_build"></a>How to build Ghostscript from source (PC version)</h2>

<p>
To build Ghostscript you need MS-DOS version 3.3 or later and
Borland/Inprise C/C++ (4.0 or later); Microsoft Visual C++ (version 4.0 or
later); Watcom C/386 (version 8.5 or later) or C++ (any version); or the
free djgpp + go32 development system. The options in the makefiles are
chosen to strike a balance between RAM consumption and likely usefulness.
If you run <b><tt>make</tt></b> in directory <em>{dir}</em>, the default
configuration generates an executable that assumes the Ghostscript
initialization and font files are in directory
<em>{dir}</em><b><tt>\lib</tt></b>.
<p>
Note that the <b><tt>make</tt></b> program supplied with each PC compiler
has a different name. We refer to this program generically as
<b><tt>make</tt></b> everywhere else in this document, but you will find the
correct name for each compiler in the relevant section below that discusses
that compiler.
<p>
You must have <b><tt>COMMAND.COM</tt></b> in your path to build Ghostscript.
After making the changes needed to choose features and devices to build into
the executable, you must create the directory where the compiler will do its
work (normally the <b><tt>obj</tt></b> subdirectory of the current
directory) and the directory where the compiled code will be placed
(normally the <b><tt>bin</tt></b> subdirectory). Then to build the
Ghostscript executable all you need do is give the <b><tt>make</tt></b>
command.
<p><a name="Make_begin"></a>
A special make target "<b><tt>begin</tt></b>" attempts to compile all the
<b><tt>.c</tt></b> files in the current directory. Some of these
compilations will fail, but the ones that succeed will go considerably
faster because they don't individually pay the overhead of starting up the
compiler. So a good strategy for building the executable for the first
time, or after changing a widely used <b><tt>.h</tt></b> file, is to do the
fast compilation of everything possible, then the controlled compilation of
everything that failed in the first step:
<blockquote><b><tt>
make begin<br>
make
</tt></b></blockquote>
<p>
<b><em>Note:</em></b> if you unpack the Ghostscript sources on a DOS or MS Windows
system from a Unix tar file, the unpacked files have linefeed alone as the
line terminator (the Unix convention) instead of carriage return + linefeed
(the Microsoft convention), which may make the C compiler unhappy. One
simple way to fix this, if you have the InfoZIP <b><tt>zip</tt></b> and
<b><tt>unzip</tt></b> programs, is
<blockquote><table cellpadding=0 cellspacing=0>
<tr> <td><b><tt>zip -l CVTEMP.zip *.bat *.c *.h</tt></b>
<td>
<td>(Letter "l", not the digit "1")
<tr> <td><b><tt>unzip -o CVTEMP.zip</tt></b>
<td>
<td>(Rewrite all the same files correctly)
<tr> <td><b><tt>del CVTEMP.zip</tt></b>
<td>
<td>(Delete the temporary zip file)
</table></blockquote>
<h3><a name="Borland_build"></a>Borland/Inprise environment</h3>
<p>
To compile Ghostscript with the Borland/Inprise environment (hereafter
referred to as just "Borland"), you need Borland C++ (version 4.0 or later);
specifically the compiler, <b><tt>make</tt></b> utility, and linker. You
also need either the Borland assembler (version 1.0 or later) or the
Microsoft assembler (version 4.0 or later).
<p>
To create "<b><tt>makefile</tt></b>", give the command
<blockquote><b><tt>
echo !include "src\bcwin32.mak" >makefile
</tt></b></blockquote>
<p>
To run the <b><tt>make</tt></b> program, give the commmand
<blockquote><b><tt>
make
</tt></b></blockquote>
<p>
Besides the source files and the makefiles, you need:
<blockquote><table cellpadding=0 cellspacing=0>
<tr valign=top> <td>*<b><tt>.bat</tt></b>
<td>
<td>(a variety of batch files used in the build process)
</table></blockquote>
<p>
Comments in the makefiles describe the configuration parameters. If your
configuration is different from the following, you should definitely read
those comments and see if you want or need to change any of this:
<ul>
<li>The compiler files are in <b><tt>C:\BC</tt></b> and its subdirectories.
<li>You are using the Borland assembler <b><tt>tasm</tt></b>.
<li>You want an executable that will run on any 32-bit PC-compatible,
regardless of processor type (80386, 80486, Pentium, or compatible) and
regardless of whether a math coprocessor (80x87) is present -- an issue only
with 80386 processors.
</ul>
<p>
<b>Notes</b>
<ul>
<li>A user reports that the Borland C++ 4.00 with patch 1-6 doesn't
produce a working executable of Ghostscript 5.03. We can't test this,
since we no longer have this compiler.
<li>Borland C++ 4.5 has a bug or bugs that cause(s) the 32-bit Windows
executable to crash if you give any @-files on the command line. Among
other things, this makes the uniprint driver unusable, because it references
the .upp configuration files this way. This problem may possibly be fixed
by one or more of the patch files on
<blockquote>
<a href="ftp://ftp.borland.com/pub/borlandcpp/devsupport/patches/bc4_5/"
class="offsite">ftp://ftp.borland.com/pub/borlandcpp/devsupport/patches/bc4_5/</a>
</blockquote>
<li>Borland C++ 4.52 has a bug that causes the 32-bit Windows executable to
fail during startup. Borland (now Inprise) provides a patch for this bug
in
<blockquote>
<a

class="offsite">ftp://ftp.borland.com/pub/borlandcpp/devsupport/patches/bc4_5/bc45xp1.zip</a>
</blockquote>
<li>Borland C++ 5.0 and 5.01 have a code generator bug that generates
incorrect code for the construct <b><tt>!file_is_valid()</tt></b>. Do not
attempt to compile Ghostscript with these compilers. If you want to report
this bug to Borland, send them the result of compiling
<b><tt>ziodev.c</tt></b> and tell them to look at the code generated for
<b><tt>file_is_valid()</tt></b> and <b><tt>!file_is_valid()</tt></b>. We
don't know whether Borland C++ 5.02 still has this problem.
<li>When building for the MS Windows Win32s environment, the make
process will stop after it has created <b><tt>genarch.exe</tt></b>.
You should then run "<b><tt>_genarch.bat</tt></b>", wait until
<b><tt>genarch</tt></b> has finished and then exit MS Windows. Then type
"<b><tt>make</tt></b>" again to restart the make process.
</ul>
<h3><a name="Microsoft_build"></a>Microsoft environment</h3>
<p>
NOTE: We have received reports that the Microsoft Visual C++ 5.0 and 6.0
compilers produce incorrect code for Ghostscript version 6.0 and later, from
the same source code that compiles and runs correctly with other compilers.
You may also want to try
out the <a href="#IntelWin32_build">Intel C/C++ compiler</a>, which can
be integrated into the Microsoft Visual C++ environment.
<p>
To compile Ghostscript with the Microsoft environment, you need Microsoft
Visual C++ 4.0 or later with its associated "<b><tt>nmake</tt></b>" utility
and linker. If you're using version 4.x, before building, in
<b><tt>msvc32.mak</tt></b> find the line
"<b><tt>MSVC_VERSION = 5</tt></b>" and change it to
"<b><tt>MSVC_VERSION = 4</tt></b>".
<p>
To create "<b><tt>makefile</tt></b>", give the command
<blockquote><b><tt>
echo !include src\msvc32.mak >makefile
</tt></b></blockquote>
<p>
To run the <b><tt>make</tt></b> program, give the commmand
<blockquote><b><tt>
nmake
</tt></b></blockquote>
<p>
You may get error messages during compilation about <b><tt>/QI0f</tt></b>
being an undefined switch, or the message "dwmain32.def: EXETYPE not
supported for platform; ignored" during linking. Ignore them.
<p>
The Microsoft VC++ 5.0 compiler locks up when compiling
<b><tt>gxi12bit.c</tt></b> with <b><tt>/O2</tt></b>. Compile this file
without <b><tt>/O2</tt></b>.
<p>
The Microsoft VC++ 5.0 compiler produces a non-working executable if
compiling without stack checking. Don't change the setting
<b><tt>TDEBUG=1</tt></b> in <b><tt>msvc32.mak</tt></b>.
<h3><a name="Self-extracting_executables"></a>Making self-extracting executables</h3>
<p>
You can build self-extracting Windows executables of Ghostscript. (This is
not needed to use Ghostscript.) Currently this requires both the
Borland/Inprise and the Microsoft compilers, and also two pieces of
third-party software:
<ul>
<li><b><tt>WinZipSE</tt></b>, available from <a
href="http://www.winzip.com/winzipse.html"
class="offsite">http://www.winzip.com/winzipse.html</a>.
This is not free.
<li><b><tt>zip</tt></b>, available from <a
href="http://www.info-zip.org/pub/infozip/Zip.html" class="offsite">
http://www.info-zip.org/pub/infozip/Zip.html</a>. This is free.
</ul>
<p>
You will have to edit <b><tt>src/winint.mak</tt></b> to define
<b><tt>WINZIPSE_XE</tt></b> and <b><tt>ZIP_XE</tt></b> respectively as the
path names of these programs. See <a href="Release.htm">Release.htm</a> for
the detailed procedure.
<h3><a name="Watcom_build"></a>Watcom environment</h3>
<p>
Because of limitations in the way that Watcom implemented their
<b><tt>wmake</tt></b> program, you must run the Watcom tools under MS
Windows, even if you are generating a DOS executable. This is very
unfortunate, and there is no good technical reason for it, but we were
unable to persuade Watcom (now Powersoft) to do anything about it.
<p>
To use the Watcom compiler, add to <b><tt>AUTOEXEC.BAT</tt></b> the line
"<b><tt>set DOS4G=quiet</tt></b>". Check that
<b><tt>AUTOEXEC.BAT</tt></b> also contains a line of the form
"<b><tt>set WATCOM=</tt></b><em>{wcdir}</em>" where <em>{wcdir}</em> is
the directory where you installed the Watcom tools, and that the setting of
<b><tt>PATH</tt></b> includes <em>{wcdir}</em><b><tt>\binnt</tt></b> (or
<b><tt>%WATCOM%\binnt</tt></b>) before <em>{wcdir}</em><b><tt>\binw</tt></b>
(or <b><tt>%WATCOM%\binw</tt></b>). Then to create
"<b><tt>makefile</tt></b>":
<blockquote><table cellpadding=0 cellspacing=0>
<tr> <th align=left>For
<td>
<th align=left>Give the command
<tr> <td colspan=3><hr>
<tr> <td>DOS
<td>
<td nowrap><b><tt>echo !include src\watc.mak >makefile</tt></b>
<tr> <td>MS Windows
<td>
<td nowrap><b><tt>echo !include src\watcw32.mak >makefile</tt></b>
</table></blockquote>
<p>
Before compiling, change the definition of the <b><tt>WCVERSION</tt></b>
macro in the makefile (<b><tt>watc.mak</tt></b> or
<b><tt>watcw32.mak</tt></b>) to the version of the Watcom compiler you are
using. This is necessary to handle some minor incompatibilities between
versions.
<p>
To run the <b><tt>make</tt></b> program, give the commmand
<blockquote>
<b><tt>wmake -u</tt></b>
</blockquote>
<p>
For information on using the GNU <b><tt>make</tt></b> program with the
Watcom compiler to build MS-DOS executables, which avoids the limitations in
<b><tt>wmake</tt></b>, see <a href="New-user.htm#MS-DOS">here</a>.
<h3><a name="Cygwin32_build"></a>Cygwin32 gcc</h3>
<p>
A user reports that it is possible to compile Ghostscript for MS Windows NT
using the Cygwin32 gcc compiler, GNU <b><tt>make</tt></b>, and the
<b><tt>unix-gcc.mak</tt></b> makefile, with only two small source code
changes:
<ul>
<li>Add "<b><tt>b</tt></b>" to the call to <b><tt>fopen</tt></b> in <b><tt>gp_open_scratch</tt></b>
<li>Mirror the <b><tt>gp_ntfs</tt></b> logic for <b><tt>gp_file_name_is_absolute</tt></b>
</ul>
<p>
Information about this compiler and environment is at the Cygnus site:
<blockquote>

<p>

<h3><a name="IntelWin32_build"></a>Intel C/C++ environment</h3>
<p>
Intel provides a C/C++ compiler that is compatible with the <a
href="#Microsoft_build">Microsoft Visual C++ environment</a>. The main
advantage of this compiler over MSVC 5.0 and 6.0 is that it produces
working code even when all optimizations are enabled and when stack checking
is disabled.
<p>
To build Ghostscript using the Intel C/C++ compiler, you have to make the
following small changes in the makefiles:
<ul>
<li>Find and change the second occurrence of
"<b><tt>COMPILE_FULL_OPTIMIZED</tt></b>" to "<b><tt>/O2</tt></b>" in file
<b><tt>msvccmd.mak</tt></b>. <li>Override "<b><tt>TDEBUG</tt></b>",
"<b><tt>COMP</tt></b>", and "<b><tt>COMPAUX</tt></b>" when invoking
<b><tt>nmake</tt></b>.
</ul>
<p>
More specifically, use "<b><tt>TDEBUG=0</tt></b>" and set both
"<b><tt>COMP</tt></b>" and "<b><tt>COMPAUX</tt></b>" to the full path of
<b><tt>icl</tt></b> (for example
"<b><tt>COMP=C:\intel\compiler45\bin\icl</tt></b>" if the Intel C/C++
compiler V4.5 was installed to <b><tt>C:\intel</tt></b>). It is suggested
that you use a batch file to launch <b><tt>nmake</tt></b>, since the command
line processes the "<b><tt>=</tt></b>" on its own. Also, you may need to
execute <b><tt>vcvars32.bat</tt></b> and <b><tt>iccvars.bat</tt></b> to
register the proper paths for the compiler, its include files and its
libraries.
<p>
You can buy or download a 30-day evaluation version of the Intel C/C++
compiler from Intel's Software Performance Tools web site:

<h2><a name="Mac_build"></a>How to build Ghostscript from source (Mac version)</h2>
<h3><a name="MacOS"></a>Traditional MacOS</h3>
<p>
There are additional Mac-specific source files in a distribution
separate from the rest of Ghostscript. In addition to the standard Ghostscript
sources, you will need the following files:
<blockquote><dl>
<dt><a href="ftp://mirror.cs.wisc.edu/pub/mirrors/ghost/AFPL/mac/"
class="offsite">ftp://mirror.cs.wisc.edu/pub/mirrors/ghost/AFPL/mac/</a>macgs-###-src.sit.bin

<dd>Fonts (properly not to build MacGS but to install it)
</dl></blockquote>
<p>
If you don't have a program to expand and unpack these files, get the free
<b>StuffIt Expander</b> program from your favorite Macintosh archive.
<p>
In the standard method of building Ghostscript, these files except the JPEG
are unpacked into one big directory; the JPEG stuff is unpacked into a
directory called <b><tt>jpeg-6</tt></b> under the main directory. The Macintosh
stuff is also unpacked into its own directory, called "Mac Specific".
However, if you like you can set up all these files in this hierarchy:
<blockquote><table cellpadding=0 cellspacing=0>
<tr><th colspan=4 bgcolor="#CCCC00"><hr><font size="+1">Suggested Macintosh hierarchy</font><hr>
<tr valign=bottom>
<th align=left colspan=4><b><tt>Ghost Dev</tt></b>

<p>
Once everything is laid out, look at the file <b><tt>Worksheet</tt></b> in
the "<b><tt>Mac Specific</tt></b>" folder for complete steps to build the
system with either MPW or CodeWarrior.
<p>
Some versions of CodeWarrior on the PowerPC have a code generation bug that
causes the compiled Ghostscript to occasionally produce bad output. To
avoid triggering this bug, do not use the "Use FMADD & FMSUB" Code Gen
option. We recommend using the following options (for CodeWarrior 4, all
patches applied):
<blockquote><b><tt>
Code Gen:
<br>Struct alignment: PowerPC
<br>Traceback Tables: Inline
<br>Target Processor: 750 (or as appropriate for your system)

<h3><a name="Rhapsody"></a>Rhapsody OS</h3>
<p>
Currently, building with Rhapsody is only supported with non-display
devices, such as <b><tt>pdfwrite</tt></b> for converting PostScript to PDF,
raster file devices such as <b><tt>pbmraw</tt></b>, and printers. For this
environment, use <b><tt>unixansi.mak</tt></b> with these additional

<hr>
<h2><a name="Unix_build"></a>How to build Ghostscript from source (Unix version)</h2>
<p>
Before issuing the <b><tt>make</tt></b> command to build Ghostscript, you
have to make some choices, for instance
<ul>
<li>which compiler to use;
<li>what features and devices to include;
<li>whether to use system libraries for PNG and zlib;
<li>and how to handle issues for your particular platform.
</ul>
<p>
Be sure to check the sections on <a
href="#Tool_specific_issues">tool-</a>, <a
href="#OS_specific_issues">OS-</a>, and <a
href="#Hardware_specific_issues">hardware-</a>specific issues for notes
on your particular platform and compiler. In fact, that is the
<b><em>first</em></b> place to check if you build Ghostscript and it crashes
or produces obviously incorrect results.
<h3><a name="Multi_architecture_makefile"></a>The multi-architecture makefile</h3>
<p>
Especially if you are working in a Unix environment with multiple CPU types,
operating systems, and/or C compilers, you may find the file
<b><tt>all-arch.mak</tt></b> useful. This user-contributed file includes
"wrappers" for the Unix makefiles for many different common environments.
The author of this file notes:
<blockquote>
<p>
This makefile allows you to execute
<pre>
make `hostname`
</pre>
<p>
on any machine on a network, without having to examine the Makefile for a
specific target name. Also, some of the targets in the Makefile incorporate
special changes in compiler options for certain files, to work around
compiler bugs that Ghostscript has been so good at exposing. Having that
special handling written down in a Makefile proves very convenient.
<p>
I don't do "make install" until I've done
<pre>
cd ...build-directory.../gs-x.yz
cd lib
../bin/gs ../examples/tiger.ps
</pre>
<p>
and verified that the famous tiger can be correctly displayed. Also, the
"make install" step is careful to first remove any existing
<b><tt>$(BINDIR)/gs</tt></b>, then install a new gs there with a hard link
to gs-x.yz.
<p>
That way, each installation makes gs a synonym for the latest release,
but earlier ones remain in place in case backtracking is needed, which
I've fairly often wanted to do when investigating changed behavior, or
a suspected bug.
<p>
When I've been experimenting with a new feature, such as GNU readline
support, I change the setting of GS from gs to ngs (new gs), so as not
to break any existing programs by the installation of an experimental
version.
</blockquote>
<h3><a name="UNIX_makefile"></a>Setting up "makefile"</h3>
<p>
The files <b><tt>src/unix</tt></b>*<b><tt>.mak</tt></b> are the makefiles for
Unix platforms, and you choose one based on what compiler you use. To
build Ghostscript, however, you must use the simple command
"<b><tt>make</tt></b>", which must find the file "<b><tt>makefile</tt></b>"
(or "<b><tt>Makefile</tt></b>"). If your system supports symbolic links,
set up "<b><tt>makefile</tt></b>" like this.
<blockquote><table cellpadding=0 cellspacing=0>
<tr> <td>GNU gcc:
<td>
<td nowrap><b><tt>ln -s src/unix-gcc.mak makefile</tt></b>
<tr> <td>Non-gcc ANSI C compiler:
<td>
<td nowrap><b><tt>ln -s src/unixansi.mak makefile</tt></b>
<tr> <td>"Traditional" C compiler:
<td>
<td nowrap><b><tt>ln -s src/unixtrad.mak makefile</tt></b>
</table></blockquote>
<p>
If your system doesn't support symbolic links, first finish all changes to
the compiler-specific makefile, then make a hard link, omitting the
<b><tt>-s</tt></b> switch.
<p>
The makefile distributed with Ghostscript selects the following devices
to include in the build:
<blockquote><table cellpadding=0 cellspacing=0>
<tr><th colspan=3 bgcolor="#CCCC00"><hr><font size="+1">Devices included as distributed</font><hr>
<tr valign=bottom>
<th align=left>Type
<td>
<th align=left>Devices
<tr> <td colspan=3><hr>
<tr valign=top> <td>Display

<td>X Windows
<tr valign=top> <td>Printers

<tr valign=top> <td>File formats
<td>
<td>Group 3 & Group 4 fax; JPEG; PCX; PBM, PGM, PKM, & PPM; TIFF; PostScript images; PNG; distilled PDF, PostScript, and EPS; PCL XL ("PCL 6")
</table></blockquote>
<p>
The <b><tt>unix</tt></b>*<b><tt>.mak</tt></b> files explicitly compile and
link the JPEG, PNG, and zlib libraries into the executable. If your Unix
system already includes the PNG and zlib libraries -- probably in
<b><tt>/usr/lib/libpng.</tt></b>{<b><tt>a</tt></b>,<b><tt>so</tt></b>} and
<b><tt>/usr/lib/libz.</tt></b>{<b><tt>a</tt></b>,<b><tt>so</tt></b>} -- and
you would rather use those copies, change the definition of
<b><tt>SHARE_LIBPNG</tt></b> and <b><tt>SHARE_ZLIB</tt></b> from 0 to 1 in
the relevant <b><tt>unix</tt></b>*<b><tt>.mak</tt></b> file before
compiling. Note that if you do this, you will get non-debug versions of
these libraries even if you selected <b><tt>DEBUG</tt></b> in the makefile.
At the insistence of some users, we have also provided the ability to do
this with the JPEG library (<b><tt>SHARE_JPEG</tt></b>), but should not use
it: in order to be compatible with Adobe interpreters (which do not follow
the JPEG standard exactly), Ghostscript has to compile the IJG code with
the non-standard definition
<blockquote><b><tt>
#define D_MAX_BLOCKS_IN_MCU 64
</tt></b></blockquote>
<p>
and since shared versions of this library will not have been compiled this
way, you will get errors on some valid PostScript and PDF input files. Note
also that because not all the JPEG library header files that Ghostscript
uses are normally installed in <b><tt>/usr/include</tt></b>, you must have
the source code for this library available even if you set
<b><tt>SHARE_JPEG</tt></b> to 1.
<p>
If the X11 client header files are located in some directory which your
compiler does not automatically search, you must change the
<b><tt>XINCLUDE</tt></b> macro in the makefile to include a specific
<b><tt>-I</tt></b> switch. See the comment preceding
<b><tt>XINCLUDE</tt></b> in the makefile.
<p>
Currently Ghostscript is set up to compile and link in a generic Unix
environment. Some Unix environments may require changing the
<b><tt>LDFLAGS</tt></b> macro in the makefile; be sure to check the <a
href="#Unix_build">Unix section</a> for your specific tools, operating
system, and hardware.
<p>
Ghostscript uses ANSI syntax for function definitions. Because of this,
when compiling with <b><tt>cc</tt></b> ("traditional" C), it must
preprocess each <b><tt>.c</tt></b> file to convert it to the older syntax
defined in Kernighan and Ritchie, which is what most current Unix compilers
(other than gcc) support. This step is automatically performed by a
utility called <b><tt>ansi2knr</tt></b>, which is included in the
Ghostscript distribution. The makefile automatically builds
<b><tt>ansi2knr</tt></b>. The <b><tt>ansi2knr</tt></b> preprocessing step
is included in the makefile rule for compiling <b><tt>.c</tt></b> files.
<b><tt>ansi2knr</tt></b> creates a file called
<b><tt>_temp_</tt></b><em>$$</em><b><tt>.c</tt></b> to hold the converted
code, where <em>$$</em> is the process ID. If for some reason you want to
change this name, it is defined in a script file <b><tt>ccgs</tt></b>.
<h3><a name="Tool_specific_issues"></a>Tool-specific issues</h3>
<h4><a name="gcc_27x"></a>gcc 2.7.*</h4>
<p>
Some of the issues in using gcc are very specific to the particular
computer, the particular version of the operating system, and the
particular version of gcc available to you. You can check the version of
gcc with the <b><tt>gcc --version</tt></b> command.
<p>
An optimizer bug in gcc versions 2.7.0, 2.7.1, and 2.7.2 causes the
compiler to generate incorrect code. The makefile works around this, but
we recommend that if possible you use either an earlier or a later version
of gcc; for instance, gcc 2.5.8, gcc 2.6.3, 2.7.2.1 or later which don't
have this bug. Note, however, that gcc has other problems on some
platforms, so please read the section for your specific platform.
<h4><a name="GNU_make"></a>GNU make</h4>
<p>
Current versions of GNU <b><tt>make</tt></b> have no problems, but GNU

<h4><a name="Linux"></a>Linux</h4>
<ul>
<li>If you build on Linux with X11 R6 or later, you may get link-time error
messages about undefined references to various functions beginning with
"SMC" and "ICE". If this happens, make sure that <b><tt>XLIBS</tt></b> in
the makefile is set to
"<b><tt>Xt SM ICE Xext X11</tt></b>" rather than
"<b><tt>Xt Xext X11</tt></b>".
<li>With gcc version 2.6.3 or later, you may encounter an incompatibility
in object formats (<b><tt>a.out</tt></b> vs. ELF) with the XFree86 library.
Typically, <b><tt>ld</tt></b> complains that some X library is not found,
or that many <b><tt>Xlib</tt></b> or <b><tt>Xt</tt></b> functions are not
found in the library (similar to the messages for omitting
<b><tt>SM</tt></b> and <b><tt>ICE</tt></b> from <b><tt>XLIBS</tt></b>). Or
you get a message when you start Ghostscript that the program or the shared
library is an unrecognized format.
If this happens, edit <b><tt>unix-gcc.mak</tt></b> to add the switches
"<b><tt>-b i486-linuxaout</tt></b>" to both <b><tt>CFLAGS</tt></b> and
<b><tt>LDFLAGS</tt></b>, then "<b><tt>make clean</tt></b>" followed by
"<b><tt>make</tt></b>"). If this doesn't help, or if other strange things
happen, contact your Linux supplier or support resource.
<li>A few of Ghostscript's drivers are multi-threaded (currently only those
whose names begin with "bmpa"). These drivers require <b><tt>libc</tt></b>
version 6 or higher. Some Linux distributions, including Red Hat
distributions before 5.0, have <b><tt>libc</tt></b> version 5, so these
drivers may not compile. If this happens, remove these drivers (from the
definitions of <b><tt>DEVICE_DEVS*</tt></b> in
<b><tt>unix-gcc.mak</tt></b>), and, if you wish, substitute the
corresponding single-threaded drivers, whose names don't include the "a".

<p>
You may want to create <a href="http://www.rpm.org">RPM</a> (<b>R</b>ed Hat

of standardization of installation directory names between Linux releases,
Ghostscript does not come with any RPM specification files. You may wish to

The following instructions may work for the Ghostscript 6.0x distributions,
once you have RPM spec files that you believe are appropriate.
<p>
To create RPMs for Ghostscript N.NN:
<ul>
<li>Change to your source directory (<b><tt>/usr/src/redhat</tt></b> for Red Hat
Linux 5.1).
<li>Copy <b><tt>ghostscript-N.NN*.tar.gz</tt></b> (4 source files) to the
<b><tt>SOURCES</tt></b> subdirectory.
<li>Copy <b><tt>ghostscript-fonts-std-6.0.tar.gz</tt></b> and
<b><tt>ghostscript-fonts-other-6.0.tar.gz</tt></b> to the
<b><tt>SOURCES</tt></b> subdirectory.
<li>From <b><tt>SOURCES/ghostscript-N.NN.tar.gz</tt></b>,
<ul>
<li>extract <b><tt>rpm-conf.dif</tt></b> and copy to
<b><tt>SOURCES/ghostscript-N.NN-config.patch</tt></b>
<li>extract <b><tt>gs.rps</tt></b> and copy to
<b><tt>SPECS/ghostscript-N.NN.spec</tt></b>
<li>extract <b><tt>gs-fonts.rps</tt></b> and copy to
<b><tt>SPECS/ghostscript-fonts-N.NN.spec</tt></b>
</ul>
If the contents of these files have become out of date, you
will need to update the version number N.NN in the spec files,
and update the patch file.
<li> Change to the SPECS subdirectory and then execute the commands
<blockquote><b><tt>
rpm -ba ghostscript-N.NN.spec<br>
rpm -ba ghostscript-fonts-N.NN.spec
</tt></b></blockquote>
This will create the RPM files
<blockquote><b><tt>
RPMS/i386/ghostscript-N.NN-1.i386.rpm<br>
RPMS/noarch/ghostscript-fonts-N.NN-1.noarch.rpm<br>

<h4><a name="NeXTSTEP"></a>NeXTSTEP / OpenSTEP</h4>
<ul>
<li>If you are using a NeXTSTEP version before 3.3, please get a no-cost
upgrade (along with Y2K patches) from Apple.
<li>For all NeXTSTEP systems, use <b><tt>unix-gcc.mak</tt></b>. Make the
following changes:
<ul>
<li>In <b><tt>unix-aux.mak</tt></b> (and <b><tt>ugcclib.mak</tt></b>, if you
are using only the library) change the definition of <b><tt>INCLUDE</tt></b>
to "<b><tt>INCLUDE=/usr/include/bsd</tt></b>";
<li>in <b><tt>unix-gcc.mak</tt></b>:
<ul>
<li>change <b><tt>CC=gcc</tt></b> to <b><tt>CC=cc</tt></b>;
<li>change the definition of <b><tt>STDLIBS</tt></b> to only
<b><tt>-lm</tt></b>;
<li>change <b><tt>SYNC=posync</tt></b> to <b><tt>SYNC=nosync</tt></b>;
<li>add <b><tt>-D_POSIX_SOURCE</tt></b> to <b><tt>CFLAGS</tt></b> and remove
<b><tt>-g</tt></b>;
<li>remove <b><tt>-Wstrict-prototypes</tt></b> from <b><tt>GCFLAGS</tt></b>,
and if you are using NeXTSTEP 3.3 (with gcc 2.5.8), also remove
<b><tt>-Wmissing-declarations</tt></b>;
</ul>
<li>to the end of <b><tt>Fontmap.GS</tt></b> add the line
"<b><tt>/Ohlfs /Courier ;</tt></b>".
</ul>
<li>If you are running the Pencom co-Xist X server (development version),
the X headers and libraries are in the default places, so change the
makefile definitions of <b><tt>XINCLUDE</tt></b> and
<b><tt>XLIBDIRS</tt></b> to empty strings.
</ul>
<h4><a name="SCO"></a>SCO Unix/Xenix</h4>
<ul>
<li>See also "<a href="#386_Unix">386 Unix</a>" and
"<a href="#System_V">System V Unix platforms</a>".
<li>The standard cc compiler on SCO OpenServer v5 has optimizer bugs.
Compile without -O.
<li>The SCO Unix C compiler apparently can't handle the
<b><tt>P</tt></b><em>n</em> macros in <b><tt>std.h</tt></b>. If you get
strange compilation errors on SCO Unix, ask SCO for a compiler fix.
<li>Meanwhile, to use gcc with SCO ODT, see <b><tt>unix-gcc.mak</tt></b>
for the appropriate switch settings.
<li>Because of a bug in SCO's floating point emulator, gcc 2.3.3 produces
code that causes crashes on machines without hardware floating point. Use
a different compiler on these machines.
<li>If you aren't using the X11 driver, you must add
<b><tt>-lsocket</tt></b> to the value of <b><tt>EXTRALIBS</tt></b> to link
the date and time functions.
<li>If you want to use direct frame buffer addressing instead of X Windows,
include the relevant frame buffer devices (<b><tt>$(DD)ega.dev</tt></b>,
<b><tt>$(DD)vga.dev</tt></b>, etc.) and change the definition of
<b><tt>EGAVGA</tt></b> to <b><tt>$(EGAVGA_SCO)</tt></b> as indicated in
<b><tt>devs.mak</tt></b>. <b>Note</b>: this works with SuperVGA displays
only for 800x600x16 mode.
<li>If the display looks "smeared", try recompiling
<b><tt>gdevpcfb.c</tt></b> with <b><tt>-O0</tt></b>.
<li>If Ghostscript crashes, use the <b><tt>-q</tt></b> switch or redirect
console output to a file.
<li>If your compiler accepts both the <b><tt>-Xt</tt></b> and
<b><tt>-Xa</tt></b> switches, use <b><tt>-Xt</tt></b>. Even though this
causes the compiler to use incorrect rules for computing the result types
of "<b><tt><<</tt></b>" and "<b><tt>>></tt></b>",
<b><tt>-Xa</tt></b> enables optimizations that produce incorrect code.
<li>For SCO ODT 2.0, in addition to <b><tt>-D__SVR3</tt></b> and
<b><tt>-DSYSV</tt></b>, you need to specify <b><tt>-Dsco</tt></b>,
<b><tt>-DUSG</tt></b>, and <b><tt>-DMALLOC_0_RETURNS_NULL</tt></b>. For
SCO ODT, you need
"<b><tt>EXTRALIBS=-lX11 -lsocket -lmalloc</tt></b>", or maybe
only <b><tt>-lsocket</tt></b> depending on the version), and for SCO ODT
2.0, you must also specify <b><tt>-lc_s</tt></b>. For SCO Xenix, you need
"<b><tt>EXTRALIBS=-lmalloc</tt></b>".
<li>For SCO OpenServer 5.0.5, add <b><tt>-L/usr/local/lib</tt></b> to
<b><tt>LDFLAGS</tt></b>.
<li>For all SCO systems, set "<b><tt>XINCLUDE=</tt></b>" and
"<b><tt>XLIBDIRS=</tt></b>".
</ul>
<h4><a name="SVR4"></a>SVR4 Unix</h4>
<ul>
<li>You may need to set <b><tt>EXTRALIBS=-lnsl</tt></b>.
<li>Do <b><em>not</em></b> change <b><tt>PLATFORM=unix_</tt></b> to <b><tt>PLATFORM=sysv_</tt></b>.
<li>On SVR4 Unix platforms with dynamic linking, you may need to define
<b><tt>XLIBDIR</tt></b> as the name of the directory that holds the X
Windows libraries. Do <b><em>not</em></b> prefix the name with
"<b><tt>-L</tt></b>".
<li>For SVR4.0 systems, set <b><tt>-DSVR4</tt></b> and
<b><tt>-DSVR4_0</tt></b> in the makefile; do <b><em>not</em></b> set
<b><tt>-DSYSV</tt></b>. For SVR4.2 (or later) and Solaris 2.<em>n</em>
systems, set only <b><tt>-DSVR4</tt></b> (<b><em>not</em></b>
<b><tt>-DSVR4_0</tt></b> nor <b><tt>-DSYSV</tt></b>).
</ul>
<h4><a name="System_V"></a>System V Unix platforms</h4>
<ul>
<li>If you are using a stock System V platform that lacks
<b><tt>rename</tt></b> and <b><tt>gettimeofday</tt></b>, in the makefile
change "<b><tt>PLATFORM=unix_</tt></b>" to
"<b><tt>PLATFORM=sysv_</tt></b>".
<li>You will probably need to change the definition of
<b><tt>INSTALL</tt></b> from "<b><tt>install</tt></b>" to
"<b><tt>/usr/ucb/install</tt></b>".
</ul>
<h4><a name="Unixware"></a>Unixware</h4>
<ul>
<li>The standard cc compiler has optimizer bugs. Compile without
<b><tt>-O</tt></b>.
</ul>
<h3><a name="Hardware_specific_issues"></a>Hardware-specific issues</h3>
<h4><a name="Alpha_with_gcc"></a>Alpha with gcc</h4>
<ul>
<li>You don't have to use gcc on Alpha systems, because the bundled
compiler works.
<li>The Alpha code generator in gcc 2.7.2.1 is broken. gcc 2.5.8 and 2.6.3
are probably usable. Versions before 2.5.0 are believed not to work. We
suggest you use a recent version.
<li>If you really want to use gcc 2.7.x, here is a patch for that version
from gcc maintainer Jim Wilson

</ul>
<h4><a name="Apollo"></a>H-P Apollo</h4>
<ul>
<li>You must run the compiler in ANSI-compatible mode (that is, set <b><tt>AK=</tt></b>{null string} in the makefile); otherwise it gives incorrect error
messages for any function declared as returning a float value.
<li>The H-P Apollo compiler may not compile Ghostscript correctly. If you
get unexpected crashes at run time, use gcc.
</ul>
<h4><a name="ATT_7040"></a>AT&T 7040 R3</h4>
<ul>
<li>If Ghostscript crashes on startup, recompile with <b><tt>-O0</tt></b>
to work around compiler bugs.
</ul>
<h4><a name="Convex"></a>Convex</h4>
<ul>
<li>Use <b><tt>unixansi.mak</tt></b>. Do not invoke optimization
(<b><tt>-O1</tt></b>) because the compiler will produce incorrect code.
<li>Set <b><tt>CFLAGS</tt></b> to
"<b><tt>-no -fn -tm c1</tt></b>".
</ul>
<h4><a name="DECStations"></a>DECStations with Ultrix</h4>
<ul>
<li>If you get the compiler message "cfe: Fatal: _temp_19086.c:
Segmentation violation" or a similar one, try compiling with the
<b><tt>-oldc</tt></b> switch.
<li>You may wish to set
<p>
<b><tt>GS_LIB_DEFAULT=$(gsdatadir):/usr/lib/DPS/outline/decwin:$(gsdatadir)/fonts</tt></b>
<p>
in the makefile to add the Display PostScript font directory to the font
search path.
<li>Set
<p>
<b><tt>CFLAGS="-Olimit 2500"</tt></b>
<p>
to make the optimizer allocate enough table space.
<li>The Ultrix 4.4 C compiler compiles <b><tt>gdevm1.c</tt></b>
incorrectly. Insert the following line in the makefile rule for
"<b><tt>gdevm1.$(OBJ)</tt></b>" (the body of the rule is empty in the
standard distribution):
<p>
<b><tt>$(CCC) -oldc gdevm1.c</tt></b>
</ul>
<h4><a name="HP_RISC"></a>H-P RISC workstations</h4>
<ul>
<li>HP-UX versions before 11.0 do not support POSIX threads. Set
<b><tt>SYNC=nosync</tt></b> in the makefile before building.
<li>Ghostscript builds on H-P machines with either GNU gcc or H-P's
ANSI-capable <b><tt>cc</tt></b>. The minimal, non-ANSI-capable
<b><tt>cc</tt></b> that ships with a basic HPUX system does <b><em>not</em></b>
work. If <b><tt>cc</tt></b> on your system doesn't accept the
<b><tt>-Aa</tt></b> switch, then you need to get the full
<b><tt>cc</tt></b> or gcc.
<li>If you use H-P's compiler, be sure you have upgraded to a recent
release. Many bizarre symptoms have been reported trying to build
Ghostscript with older, buggier compilers, for example:
<ul>
<li>The link step fails with a message about "<b><tt>max</tt></b>" not being defined.
<li>The build succeeds, but the resulting executable fails to start up,
with an error message like "Initializing... Unrecoverable error: typecheck
in .registerencoding".
<li>The build succeeds, but the resulting executable produces a black
background on the first page of output.
</ul>
<li>It is reported that On HPUX 9.* you need at least compiler patch
PHSS_5723 and dld.sl patch PHSS_5734 to build Ghostscript. (As of late
1997, those patches are long obsolete; the current patches are compiler
PHSS_10357 and dld.sl PHSS_11246. It is unknown whether current
Ghostscript releases work with compiler/dld.sl versions older than these.)
<li>On HPUX 10.*, we don't know what combinations of compiler version and
switches work. It is reported that On HPUX 10.20, setting
"<b><tt>CC=c89</tt></b>" and "<b><tt>CFLAGS=+O3 $(XCFLAGS)</tt></b>"
works, contradicting the information in the next paragraph, but this may be
dependent on the specific compiler version.
<li>In either HPUX version, you need to set
"<b><tt>CC=cc -Aa</tt></b>" (or use <b><tt>-Ae</tt></b> if you
prefer), and set
"<b><tt>CFLAGS=-D_HPUX_SOURCE -O $(XCFLAGS)</tt></b>". Higher
levels of optimization than <b><tt>-O</tt></b> may work depending on your
compiler revision; some users have reported success with
<b><tt>+O3</tt></b>, some have not.
<li>Some users have reported needing <b><tt>-DNOSYSTIME</tt></b> and
<b><tt>-D_POSIX_SOURCE</tt></b> in <b><tt>CFLAGS</tt></b>, but recent tests
do not show these to be necessary.
<li>If you use gcc, it's a good idea to have a recent release -- 2.7.2.1 or
later -- but gcc 2.6.3 has been known to work with past releases of
Ghostscript. gcc versions earlier than 2.6.3, and 2.7.* earlier than
2.7.2.1, are known <b><em>not</em></b> to work. You may be able to get a working
executable with an older gcc by removing <b><tt>-O</tt></b> from
<b><tt>CFLAGS</tt></b>.
</ul>
<h4><a name="Intergraph"></a>Intergraph Clipper</h4>
<ul>
<li>Recommended settings are:
<p>
<b><tt>XCFLAGS=-w -Q -DSYSV -D__SVR3<br>
EXTRALIBS=-lbsd -lc_s<br>
CC=acc -knr<br>
PLATFORM=sysv_</tt></b><br>
<li>You will probably need to change the value of <b><tt>XLIBS</tt></b> from
"<b><tt>XLIBS=Xt X11 Xext</tt></b>" to "<b><tt>XLIBS=Xt_s X11_s Xext</tt></b>".
</ul>
<h4><a name="MIPS"></a>MIPS</h4>
<ul>
<li>There is apparently a bug in older versions of the MIPS C compiler
which causes <b><tt>gxdither.c</tt></b> to compile incorrectly if
optimization is enabled (<b><tt>-O</tt></b>). However, this bug is
definitely fixed in MipsPRO C version 6.00; with this version, compiling
with "<b><tt>-O2 -mips2</tt></b>" produces good output.
</ul>
<h4><a name="NCR_3550"></a>NCR 3550</h4>
<ul>
<li>With the NCR C Development Toolkit you must use <b><tt>-O0</tt></b>.
</ul>
<h4><a name="Pyramid"></a>Pyramid MIServer-S</h4>
<p>
See "<a href="#ATT_7040">AT&T 7040 R3</a>".
<h4><a name="RS6000"></a>IBM RS/6000 with AIX</h4>
<ul>
<li>Many versions of the AIX C compiler have bugs that have prevented
Ghostscript from compiling and linking properly. We believe that the
current Ghostscript release works around these bugs, and that
<b><tt>unixansi.mak</tt></b> with <b><tt>CC=cc</tt></b> should work.
<li>You must also edit the makefile (<b><tt>unixansi.mak</tt></b>) to change
<b><tt>INSTALL</tt></b> to <b><tt>/usr/ucb/install</tt></b>.
<li>AIX doesn't use a separate library for multi-thread support: set
<b><tt>STDLIBS=-lm</tt></b> in the makefile.
<li>If <b><tt>-DSYSV</tt></b> produces a complaint about the functions
<b><tt>index</tt></b> and <b><tt>rindex</tt></b> not being defined, try
removing it.
<li>If the xlc 1.2.1 optimizer runs out of memory, you may need to add
<b><tt>-qmaxmem=4000</tt></b> to <b><tt>CFLAGS</tt></b>.
<li>A user reports that the AIX C compiler shipped with AIX 3.2.5 compiles
Ghostscript only if invoked with "<b><tt>c89 -D_POSIX_SOURCE</tt></b>"
and <b><em>without</em></b> <b><tt>-O</tt></b>. On the other hand, another
user reports successful compilation using <b><tt>unix-ansi.mak</tt></b> and
the command line
<p>
<b><tt>make CC=c89 XCFLAGS="-DOSY_AIX -D_ALL_SOURCE -qnoro -qmaxmem=3000 -bfl" $*</tt></b><br>
<li>Apparently some (but not all) releases of the C library declare the
<b><tt>hypot</tt></b> function: if the declaration in
<b><tt>math_.h</tt></b> produces an error message, try removing it.
<li>The IBM X11R3 server is known to be buggy: use the MIT X server if
possible.
<li>The xlc 1.3.0.x compiler provided in AIX 3.2.5+ definitely will not
compile Ghostscript correctly if <b><tt>-O</tt></b> is used on all files.
A user reports that compiling <b><tt>z</tt></b>*<b><tt>.c</tt></b>,
<b><tt>gsmatrix.c</tt></b>, <b><tt>gxstroke.c</tt></b> without
<b><tt>-O</tt></b> is sufficient to produce a working executable:.
<li>Some installations of AIX 3.2.5 have what appears to be an incorrect or
inconsistent version of <b><tt>libXt.a</tt></b> in
<b><tt>/usr/lpp/X11/lib</tt></b>. If linking shows
<b><tt>XtShellStrings</tt></b> and <b><tt>XtStrings</tt></b> as unresolved
externals, set
"<b><tt>XLIBDIRS=-L/usr/lpp/X11/lib/R5 -L/usr/lpp/X11/lib</tt></b>"
rather than just "<b><tt>XLIBDIRS=-L/usr/lpp/X11/lib</tt></b>".
<li>Ghostscript has been successfully compiled and runs under AIX 4.3.3 and
the IBM C compiler version 5. The following changes were required in
unixansi.mak:
<p>
<b><tt>CC=xlc</tt></b>
<br>
<b><tt>XCFLAGS=-qalign=natural</tt></b>
</ul>
<h4>
<a NAME="Silicon_Graphics"></a>Silicon Graphics</h4>
<p>
Users have had a lot of problems with the MIPSpro compilers on SGI systems.
We recommend using gcc. If you do choose to use the MIPSpro compiler,
please read the following carefully.
<ul>
<li>
To make the optimizer allocate enough table space, set
<p><b><tt>CFLAGS="-Olimit 2500"</tt></b> (for older compilers)
<br><b><tt>CFLAGS="-OPT:Olimit=2500"</tt></b> (for newer compilers)
<p>
MIPSpro compiler version 3.19 is "older", and 7.1 is "newer"; we aren't
sure at what point in between the latter syntax was introduced.
<li>
With the compiler shipped with Irix 5.2, use the <b><tt>-ansi</tt></b>
option.
<li>
The SGI C compiler may produce warnings about "Undefined the ANSI standard
library defined macro stdin/stdout/stderr". To suppress these warnings, add
"<b><tt>-woff 608</tt></b>" to the definition of <b><tt>CFLAGS</tt></b>.
<li>
The SGI C compiler shipped with Irix 6.1 and 6.2 will not compile
<b><tt>zlib/deflate.c</tt></b> properly with optimization. Compile this file
separately without <b><tt>-O</tt></b>.
<li>
With IRIX 6.5.x and the MIPSpro 7.x compilers there have been reports about
incorrect output and binaries that cause segmentation faults. Various
solutions have been suggested and you may want to try them in this order,
until you get a working binary:
<ul>
<li>
Compile <b><tt>idict.c</tt></b> and <b><tt>isave.c</tt></b> separately
without optimization after doing a normal compile; then relink.e.g.:
<p>
<b><tt>cc -OPT:Olimit=2500 -I. -I./obj -o ./obj/idict.o -c ./idict.c</tt></b><br>
<b><tt>cc -OPT:Olimit=2500 -I. -I./obj -o ./obj/isave.o -c ./isave.c</tt></b>
<li>
Set <b><tt>CFLAGS=</tt></b> (no optimization).
<li>
Use only <b><tt>-O2</tt></b>. Compiler produces incorrect output
with <b><tt>-O3</tt></b> or "<b><tt>-Ofast=ip32 -show</tt></b>".
<li>
Irix 6.5.1m with MIPSpro compiler 7.2.1.1m, Irix 6.5.3m with MIPSpro
compiler 7.2.1, and probably other 6.5x / 7.2x combinations require
compiling with the <b><tt>-o32</tt></b> option. Compiling with the (default)
<b><tt>-n32</tt></b> option produces non-working executables.
<b><tt>-O2</tt></b> is OK (possibly except for <b><tt>idict.c</tt></b>), but
not <b><tt>-O3</tt></b>.
</ul>
</ul>
<h4><a name="Sun"></a>Sun</h4>
<ul>
<li>The Sun unbundled C compiler (SC1.0) doesn't compile Ghostscript
properly with the <b><tt>-fast</tt></b> option: Ghostscript core-dumps in
<b><tt>build_gs_font</tt></b>. With that compiler use <b><tt>-g</tt></b>,
or use gcc instead.
<li>The Sun version of <b><tt>dbx</tt></b> often gives up with an error
message when trying to load Ghostscript. If this happens, use GNU
<b><tt>gdb</tt></b> instead. (<b><tt>gdb</tt></b> is more reliable than
<b><tt>dbx</tt></b> in other ways as well.)
<li>A bug in some versions of <b><tt>zlib</tt></b> results in an undefined
symbol <b><tt>zmemcmp</tt></b> when compiling with Sun cc. Use gcc
instead.
</ul>
<h4><a name="SunOS"></a>SunOS</h4>
<ul>
<li>The <tt><b>tar</b></tt> program provided with SunOS 4.1.3 may not be
able to unpack the archives in the standard Ghostscript distribution.
Get a more recent version of <tt><b>tar</b></tt>, such as GNU
<tt><b>tar</b></tt>.
<li>In SunOS 4.1.[23], you may get undefined symbols
<b><tt>_get_wmShellWidgetClass</tt></b> and
<b><tt>_get_applicationShellWidgetClass</tt></b> when linking. Compiling
"<b><tt>-Bstatic -lXmu -Bdynamic</tt></b>" appears to work for
SC1.0. For gcc, try adding <b><tt>-static</tt></b> to
<b><tt>CFLAGS</tt></b>. To solve the problem if you are using OpenWindows
3.0 (X11R4-based Xt), ask Sun for patches 100512-02 and 100573-03.
</ul>
<h4><a name="Solaris"></a>Solaris</h4>
<ul>
<li>Solaris 2.2 may require setting "<b><tt>EXTRALIBS=-lsocket</tt></b>".
Solaris 2.3 and later seem to require "<b><tt>EXTRALIBS=-lnsl -lsocket -lposix4</tt></b>".
<li>For Solaris 2.6 (and possibly some other versions), if you set
<b><tt>SHARE_LIBPNG=1</tt></b>, <b><tt>SHARE_ZLIB=1</tt></b>, or
<b><tt>SHARE_JPEG=1</tt></b>, you may need to set
<p>
<b><tt>XLDFLAGS=-R /usr/local/</tt></b>xxx<b><tt>/lib:/usr/local/lib</tt></b>
<p>
using the full path names of the relevant directories.
<li>Solaris 2.<em>n</em> uses <b><tt>/usr/openwin/share/include</tt></b>
for the X11 libraries rather than <b><tt>/usr/local/X/include</tt></b>.
<li>Solaris 2.<em>n</em> typically has Type 1 fonts in
<b><tt>/usr/openwin/lib/X11/fonts/Type1/outline</tt></b>.
<li>For Solaris 2.<b><tt>n</tt></b> in the makefile you must change

<li>You may need to set <b><tt>XLIBDIR</tt></b> to the directory that holds
the X11 libraries, as for other SVR4 systems. Set <b><tt>-DSVR4</tt></b>

<li>If you are using the SunPRO C compiler, don't use optimization level

platforms the generated code is incorrect. With this compiler on Intel, do
not use the <b><tt>-native</tt></b> flag: floating point computations
become unacceptably inaccurate. You can use <b><tt>-xcg92</tt></b> (SPARC
V8) and <b><tt>-dalign</tt></b> for better performance.

<h2><a name="OS2_build"></a>How to build Ghostscript from source (OS/2 version)</h2>
<p>
<em>Note: This section was contributed by a user: please e-mail Hermann
Ulrichskötter <<a
href="mailto:ulrichsk@t-online.de">ulrichsk@t-online.de</a>> if you have
questions or problems.</em>
<p>
The following instructions are for building with emx 0.9d/Fix2. Be warned
that with this version of gcc/emx, compiler optimization flags '-O' or '-O1'
will produce non-working output.
<ul>
<li>The relevant makefile is <b><tt>os2.mak</tt></b> The gcc/emx 0.9b (or
later) compiler and IBM <b><tt>NMAKE.EXE</tt></b> are required.
<li>For gcc/emx versions 0.9c and later, the <b><tt>LINK386</tt></b>
command must <b><em>include</em></b>
"<b><tt>$(COMPBASE)\lib\end.lib</tt></b>"; version 0.9b requires
<b><em>omitting</em></b> it. The current <b><tt>os2.mak</tt></b> file does
include this file in the <b><tt>LINK386</tt></b> command, so if you are
using 0.9b, delete this file reference before building.
<li>Be sure you are using the standard OS/2 shell, <b><tt>CMD.EXE</tt></b>.
Some other shells have bugs or differences that cause the makefile not to
work.
<li>Make sure you followed the instructions in "How to unpack the source
code" and "How to unpack the third-party libraries".
<li>Use jpegsrc_v6b.tar.gz, zlib.tar.gz and libpng-1.0.3.tar.gz. Earlier
versions may not work.
<li>If you wish to include support for XFree86, edit the makefile
to change <b>BUILD_X11=0</b> to <b>BUILD_X11=1</b>.
XFree86 for OS/2 can be obtained from
<a href="http://borneo.gmd.de/~veit/os2/xf86os2.html">
http://borneo.gmd.de/~veit/os2/xf86os2.html</a>
You must use emx 0.9d.
</ul>
<p>
Before compiling or linking, execute <b><tt>md bin</tt></b> and <b><tt>md
obj</tt></b> in the <b><tt>gs</tt></b> directory to create the directories
for the binaries.
<p>
First, build the standard configuration:
<ul>
<li>Edit gs/src/os2.mak: find line with 'CO=-O' (Optimizer flag) and edit
this line to 'CO=-O2' (-O or -O1 do not work!).
<li>To start the make process, type <b><tt>nmake -f .\src\os2.mak</tt></b>,
from the gs-directory.
<li>One DLL and two EXEs will be produced in <b><tt>gs/bin</tt></b>:
<b><tt>gsdll2.dll</tt></b> (the Ghostscript DLL), <b><tt>gsos2.exe</tt></b>
(the Ghostscript executable) and <b><tt>gspmdrv.exe</tt></b> (the
Presentation Manager display driver). All other newly generated files will
be produced in <b><tt>gs/obj</tt></b>.
</ul>
<p>
Now, if you wish, you can edit OS2.MAK to suit your needs, and then perform
<b><tt>nmake -f .\src\os2.mak clean</tt></b> and then <b><tt>nmake -f
.\src\os2.mak</tt></b>.

<h2><a name="VMS_build"></a>How to build Ghostscript from source (OpenVMS version)</h2>
<p>The DECC6.2-003 compiler has an optimization problem that may lead to
warnings about the "ANSI aliasing rules". DEC (Compaq) can provide a fix
for this problem. The DECC6.2-006 compiler apparently does not have the
problem.
<p>
DEC C runtime library versions 5.5 and newer have an <b><tt>exit</tt></b>
function that is compatible with all other C systems, but some older ones
don't. If you get error messages from VMS when auxiliary programs such as
<b><tt>genarch</tt></b> or <b><tt>echogs</tt></b> finish executing, find the
line in stdpre.h that reads
<blockquote><b><tt>
/*#define OLD_VMS_C*/
</tt></b></blockquote>
and remove the <b><tt>/*</tt></b> and <b><tt>*/</tt></b>, changing it to
<blockquote><b><tt>
#define OLD_VMS_C
</tt></b></blockquote>
<p>
Some versions of DEC's X server have bugs that produce broad bands of color
where dither patterns should appear, or characters displayed white on top
of black rectangles or not displayed at all. If this happens, consult the
usage documentation for how to <a href="Use.htm#X_server_bugs">work around
X server bugs</a> using X resources; also report the problem to DEC, or
whomever supplied your X server.
<p>
You may also wish to turn off the use of a backing pixmap with Ghostscript,
either to work around X server memory limitations or bugs, or to obtain
faster displaying at the expense of no redrawing when a Ghostscript window
is restored from an icon or exposed after being occluded by another window.
Again, the <a href="Use.htm">usage documentation</a> tells how to do this.
<p>
You can <a href="Fonts.htm#Precompiling">precompile any Type 1 font</a>
into C, then compile and build it into Ghostscript, as described in the
<a href="Fonts.htm">fonts documentation</a>. If you do this, then add
"<b><tt>$(PSD)ccfonts.dev</tt></b>" to <b><tt>FEATURE_DEVS</tt></b> in
<b><tt>OPENVMS.MAK</tt></b>:
<blockquote><b><tt>
$ FEATURE_DEVS = "$(PSD)psl3.dev $(PSD)pdf.dev $(PSD)dpsnext.dev $(PSD)ttfont.dev $(PSD)ccfonts.dev"
</tt></b></blockquote>
<p>
Specify the font names with <b><tt>ccfonts1</tt></b>:
<blockquote><b><tt>
$ ccfonts1 = "Courier Courier_Oblique Courier_Bold Courier_BoldOblique"
</tt></b></blockquote>
<p>
If this makes the line too long, add another line of the same form, such as
<blockquote><b><tt>
$ ccfonts1 = "Courier Courier_Oblique Courier_Bold Courier_BoldOblique"
$ ccfonts2 = "Times_Roman Times_Italic Times_Bold Times_BoldItalic"
</tt></b></blockquote>
<h3><a name="GNU_make_VMS"></a>Building with GNU make on OpenVMS</h3>
<p>
<em>Note: GNU make on OpenVMS apparently has bugs that make it stop with an
error when building Ghostscript version 5.80 or later. Until further
notice, use MMS or MMK for building Ghostscript on OpenVMS. See <a
href="#MMK_MMS_VMS">below</a> for details.</em>
<p>
As of Ghostscript version 5.0 you can use GNU make -- with the file
<b><tt>OPENVMS.MAK</tt></b> and some auxiliary <b><tt>.COM</tt></b> files
-- to build Ghostscript on OpenVMS. Use the command:
<blockquote>
<b><tt>make -fopenvms.mak "DECWINDOWS=</tt></b><em>[</em><b><tt>1.2</tt></b><em>]</em><b><tt>"</tt></b>
</blockquote>
<p>
That is, specify either "<b><tt>1.2</tt></b>" or nothing (blank) as the
value of <b><tt>DECWINDOWS</tt></b>. In Europe and other parts of the world
where ISO standard paper sizes are used, append "<b><tt>A4_PAPER=1</tt></b>"
to that line to make A4 the default paper size at run time.
<p>
If you haven't a prebuilt copy of GNU make, you'll have to build it
yourself; as of Version 3.76 (but not earlier) it is said to build properly
under OpenVMS on both VAX and Alpha. The kit is available at the
<a href="http://www.gnu.org/">Free Software Foundation's</a> ftp site and
its mirrors. See
<blockquote>
<a href="ftp://ftp.gnu.org/pub/gnu/"
class="offsite">ftp://ftp.gnu.org/pub/gnu/</a>
</blockquote>
<h3><a name="MMK_MMS_VMS"></a>Building with MMK or MMS on OpenVMS</h3>
<p>
As of Ghostscript version 5.68 you can use MMK or MMS to build Ghostscript on
OpenVMS. MMS is a utility available from Compaq (Digital);
MMK is a free program largely compatible with MMS.
<p>
Building Ghostscript with MMK or MMS uses the file
<b><tt>OPENVMS.MMK</tt></b> and some auxiliary <b><tt>.COM</tt></b> files.
To build Ghostscript with MMK or MMS, use the command:
<blockquote>
<b><tt>###/descrip=[.src]openvms.mmk/macro=("DECWINDOWS1_2=</tt></b><em>{</em><b><tt>0</tt></b>,<b><tt>1</tt></b><em>}</em><b><tt>")</tt></b>
</blockquote>
where <b><tt>###</tt></b> is either <b><tt>mmk</tt></b> or <b><tt>mms</tt></b>.
<p>
Specify <b><tt>DECWINDOWS1_2=1</tt></b> for DECWINDOWS 1.2,
<b><tt>DECWINDOWS1_2=0</tt></b> for other DECWINDOWS versions. In Europe
and other parts of the world where ISO standard paper sizes are used, add
<b><tt>,"A4_PAPER=1"</tt></b> just before the final closing parenthesis to
make A4 the default paper size at run time.
<p>

<h2><a name="Other_environments"></a>Other environments</h2>
<h3><a name="No_multi_thread"></a>Environments lacking multi-threading</h3>
<p>
All environments mentioned here by name have multi-threading capability.
However, if your environment doesn't, you can remove all need for
multi-threading by setting <b><tt>SYNC=nosync</tt></b> in the top-level
makefile. Note that you will not be able to use any so-called "async"
drivers (drivers that overlap interpretation and rasterization) if you do
this. No such drivers are in the <b><tt>DEVICE_DEVS*</tt></b> lists of any
makefile that we distribute.
<h3><a name="Plan_9"></a>Plan 9</h3>
<p>
Use <b><tt>unix-gcc.mak</tt></b>, editing it to define
<blockquote><b><tt>
CC=cc
GCFLAGS=-D_BSD_EXTENSION -DPlan9
</tt></b></blockquote>
<p>
You will also probably have to edit many path names.
<h3><a name="QNX"></a>QNX</h3>
<p>
David J. Hawkey Jr. writes that he built Ghostscript 4.03 and 5.0 under QNX
4.22, 4.23, and 4.24 using Watcom C 10.6 and that "it works quite well,
after figuring out the <b><tt>/etc/config/lpsrvr</tt></b> directives,
except for color printing to my HP DeskJet some-number-or-another". Here
is a concise presentation of changes based on the ones he made for
Ghostscript 4.03.
