MAC specific information for dmake. This information is provided in the
hope that it makes it easier to install and recompile dmake in a MAC
environment.
1. ENVIRONMENT VARIABLE SETTINGS
Only a single set of settings is available for the macintosh. There are no
sub-selections for specific OS release and/or environment.
OS - mac
OSRELEASE - NULL
OSENVIRONMENT - NULL
2. IMPLEMENTATION NOTES
This port for the Macintosh is specifically designed to be run
under MPW.
I had to make a couple of changes to dmake in order to get it to work
on the Mac. First, MPW provides no documented way to run a
subprocess, so when you use dmake, you MUST use the -n option and
execute the output. Typically, you will probably want to write a
simple script file to do these operations for you.
I added some code so that the Macintosh version of dmake can
use UNIX-style directories to specify include paths and target
and dependency file names. I.e., if you specify a file "/dir/file",
dmake will look at the file "dir:file". However, Mac dmake does not
do any translation from files specified by UNIX-style directories
in the recipe line that gets executed. If you need to translate,
you can use substitution commands. (For example,
":$(RELATIVEUNIXFILE:s,/,:,)".) This code was added so one could
execute dmake's makefile, and also so one would have an easier time
porting other UNIX makefiles. I would suggest you stick with
Macintosh-style directories for all other makefiles.
In order to run dmake, you must set (and export) the environmental
variable "OS" to "mac".
