<h2>Accessing the Source Code</h2>
<p>There are several ways to access the source code for the
FreeType packages.</p>
<ul>
<li class="emph">
<p><a href="download.html">Download a source
archive</a></p>
<p>Use this to browse, compile, and use the source
locally.</p>
</li>
<li class="emph">
<p><a href="https://git.savannah.gnu.org/cgit/freetype/">Use
the cgit page</a></p>
<p>It will let you view our source code and the changes
that occurred lately.</p>
</li>
<li class="emph">
<p>Use git access</p>
<p>The complete FreeType repositories can be downloaded
using git. Enter these commands for anonymous
read-only access of the repositories:</p>
<div class="quote">
<tt>git clone git://git.sv.nongnu.org/freetype/freetype2.git<br>
git clone git://git.sv.nongnu.org/freetype/freetype2-demos.git</tt>
</div>
<p>If you are behind a Firewall which disables port
9418, you might try the HTTP protocol:</p>
<div class="quote">
<tt>git clone https://git.sv.nongnu.org/r/freetype/freetype2.git<br>
git clone https://git.sv.nongnu.org/r/freetype/freetype2-demos.git</tt>
</div>
<p>Please read</p>
<div class="quote">
<a href="https://sv.nongnu.org/maintenance/UsingGit">https://sv.nongnu.org/maintenance/UsingGit</a>
</div>
<p>for more details on the git setup of Savannah (for
example, how to check out the git repositories with a
CVS client, if necessary).</p>
</li>
<li class="emph">
<p>Use anonymous CVS access</p>
<p>Other, no longer maintained FreeType repositories
which exist for historical interest only can be
downloaded through CVS and
viewed <a href="https://cvs.savannah.gnu.org/viewvc/?root=freetype">here</a>.
Use the following value for the <tt>CVSROOT</tt>
environment variable (or the equivalent <tt>-d</tt>
command line option of the cvs client):</p>
<div class="quote">
<tt>:pserver:anonymous@cvs.sv.nongnu.org:/sources/freetype</tt>
</div>
<p>When asked for a password, simply press Enter
for <tt>cvs login</tt>. The module names
are <tt>freetype</tt> (Freetype version 1.x,
C code), <tt>freetype1-contrib</tt>
(contributed programs), and <tt>ftpascal</tt>
(Freetype version 1.x, Pascal code).</p>
<p>The <tt>freetype2</tt> and <tt>ft2demos</tt> modules
have been transformed to git (see above) and shouldn't
be used anymore.</p>
</li>
</ul>
</div>
<!-- ************************************************** -->
<div id="bug-report">
<h2>Reporting a Bug</h2>
<p>In case you find a bug which you think is related to
FreeType, please check the problematic font with one of
our demo programs, for example <b>ftview</b>
or <b>ftstring</b>. In case the problem persists, go to
the <a href="https://savannah.nongnu.org/bugs/?group=freetype">Savannah
bug database for FreeType</a> and check whether the
problem has been reported already. Otherwise, please
submit a bug report. It might be useful to use the git
version (see above) of FreeType for testing since we don't
release FreeType very often.</p>
</div>
<!-- ************************************************** -->
<div id="language-bindings">
<h2>Language Bindings</h2>
<p>For a couple of programming languages there exist
wrappers around FreeType. Note that some of them are
quite old and probably no longer maintained.</p>
<h3><a href="https://caml.inria.fr/">Caml</a></h3>
<p>Bindings are part of
the <a href="http://cristal.inria.fr/camlimages/eng.html">CamlImages</a>
package.</p>

The Python Imaging Library
(<a href="https://www.pythonware.com/products/pil/">PIL</a>)
can be built to use FreeType for font rendering, giving
high-level access to fonts.</p>

together to cover the main parts of the Linux typography
stack, are</p>
<ul>
<li>

<div id="support-tools">
<h2>Support Tools</h2>
<p>One of the simplest way to compile FreeType is from the
command line using one of the following tools.</p>
<h3>GNU Make</h3>
<p>FreeType comes with a sophisticated build system that is
based on GNU Make. This really means a set of Makefiles
and sub-Makefiles that are used to perform the following
operations.</p>
<ul>
<li>
<p>Detect the current operating system in order to
select the appropriate default compiler settings for the
build.</p>
</li>
<li>
<p>Select the settings corresponding to a given compiler
for a given platform. For example, on Windows, the
following compilers are supported: Visual C++, GCC,
Borland C++, Watcom C++, Win32-LCC. On Unix, gcc, lcc
and standard cc are also supported through a
traditional <tt>configure</tt> script.</p>
</li>
<li>
<p>Build the list of FreeType modules automatically from
the sub-directories present in the <tt>src</tt>
directory.</p>
</li>
<li>
<p>Finally, build the library and its module as a static
library or DLL, depending on the platform and
compiler.</p>
</li>
</ul>
<p>The build system is capable of supporting several
compilers, on several platforms. However, you <b>must</b>
have a recent version of GNU Make installed to use it.
The build does <em>not work</em> with other <tt>make</tt>
tools (like BSD Make, NMake, etc.).</p>
<p>See the <a href="download.html">download section</a> for
binaries of GNU Make for Windows.</p>
<h3>FT Jam</h3>
<p>Unfortunately, the GNU Make-based build system described
above is rather complex due to various technical reasons,
one of them being the <em>really</em> weird syntax used in
Makefiles. Since release 2.0.2, the FreeType library can
also be created with an alternative build tool
named <b>Jam</b>.</p>
<p>Briefly, Jam is a small, efficient, portable and
open-source replacement for <tt>make</tt> that is both a
lot easier to use and more powerful.</p>
<ul>
<li>
<p>Jam control files (named <em>Jamfiles</em>) are
portable among platforms and compilers and thus do not
need to be edited for each specific build (unlike the
ugly <tt>Makefile.in</tt> trick used commonly on
Unix).</p>
</li>
<li>
<p>The syntax of Jamfiles is simple, expressive and
allows you to define your own functions.</p>
</li>
<li>
<p>Jam performs lots of nifty things for you, like
automatic header dependencies computations.</p>
</li>
<li>
<p>Jam only does project builds, it is not a
configuration tool and is trivially compatible with
Autoconf on Unix.</p>
</li>
</ul>
<p>Find more information on <a href="jam/index.html">the
FT Jam page</a>.</p>
