You should write a ./configure shell script, which generates makefile,
and config.h. You should include config.h in your program.
There's a program called uname, which comes with every UNIX platforms.
See man uname.
The ./configure shell script shall execute such commands like
SYSTEM=`uname -s`
.
.
.
echo "#define SYSTEM $SYSTEM" >>config.h
Or something like that.
You can add flags to your cc, and/or linker like
CCFLAGS=`gtk-config --cflags`
LDFLAGS=`gtk-config --link`
.
.
.
echo CCFLAGS=$CCFLAGS >>Makefile
echo LDFLAGS=$LDFALGS >>Makefile
And, the rest of your Makefile shall use thoes variables.
I know, that autoconf does this, but for me it's too complicated, and
sometime I run into problems (e.g. with the gEDA tools).
I just made this mail, I do not run things like this...yet. But I'm
thinkink about writing some scripts.
Anyway... I hope it helped.
