Here is my real reply finally.

Well, it doesn't interest me to check the env variables within Makefile.
Explanations now=85 :-)
My development project is based on GNUstep http://www.gnustep.org then =20=

I'm using gnustep-make (evolved custom Make environment) for my =20
development. When you decide to use GNUstep applications, you need to =20=

run a shell script in order to have a usable environments by setting =20
various env variables (most of the time you can put it in .profile or =20=

similar)

Here are GNUstep specific variables, I need to check some of them in =20
order to verify if the environments is correctly set up for my build =20
process and which flags I need to pass (depending on variables like =20
LIBRARY_COMBO, GNUSTEP_ROOT etc.)

GNUSTEP_LOCAL_ROOT=3D/GNUstep/Local
GNUSTEP_HOST=3Dpowerpc-apple-darwin7.7.0
GNUSTEP_NETWORK_ROOT=3D/GNUstep/Local
GNUSTEP_MAKEFILES=3D/GNUstep/System/Library/Makefiles
GNUSTEP_ROOT=3D/GNUstep
GNUSTEP_FLATTENED=3Dyes
GNUSTEP_HOST_OS=3Ddarwin7
GNUSTEP_HOST_VENDOR=3Dapple
GNUSTEP_HOST_CPU=3Dpowerpc
GNUSTEP_USER_ROOT=3D/Users/qmathe/GNUstep
GNUSTEP_SYSTEM_ROOT=3D/GNUstep/System
GNUSTEP_PATHLIST=3D/Users/qmathe/GNUstep:/GNUstep/Local:/GNUstep/System
CLASSPATH=3D/Users/qmathe/GNUstep/Library/Libraries/Java:/GNUstep/Local/=20=

Library/Libraries/Java:/GNUstep/System/Library/Libraries/Java
LIBRARY_COMBO=3Dgnu-gnu-gnu

Here are extra en variables I can need to check :

LDFLAGS=3D-L/opt/local/lib -L/sw/lib
SHELL=3D/bin/bash
PATH=3D/usr/local/bin:/usr/local/sbin:/gdb/bin:/gcc/bin:/opt/local/bin:/=20=

Users/qmathe/GNUstep/Tools:/GNUstep/Local/Tools:/GNUstep/System/Tools:/=20=

sw/bin:/sw/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/X11R6/bin
CFLAGS=3D-I/opt/local/include -I/sw/include
CC=3D/gcc/bin/gcc
DYLD_FRAMEWORK_PATH=3D/Users/qmathe/GNUstep/Library/Frameworks:/GNUstep/=20=

Local/Library/Frameworks:/GNUstep/System/Library/Frameworks
DYLD_LIBRARY_PATH=3D/opt/local/lib:/usr/local/lib:/gdb/lib:/gcc/lib:/sw/=20=

lib:/Users/qmathe/GNUstep/Library/Libraries:/GNUstep/Local/Library/=20
Libraries:/GNUstep/System/Library/Libraries

The problem is tricky with Mac OS X because for example by default the =20=

system tries to use Apple GCC libobjc which is not compatible with =20
GNUstep (just relying on a different Objective-C runtime), then I need =20=

to check what is precisely in DYLD_LIBRARY_PATH (when you consider CC =20=

path value especially).

The last two variables which are LD_LIBRARY_PATH equivalent for Darwin =20=

linker are important in my case because I'm doing development most of =20=

the time on top of Mac OS X (aka Darwin with GNUstep running in Apple =20=

X11.

The problem is that I could need to link libraries in /sw (Fink related =20=

packages) or not, this induces possible problems with GCC and linker =20
flags too.

I need to check various stuff like this because the project is rather =20=

complicated and I need to simplify build process as much as I can for =20=

deployment. I encounter similar problems with other OS like =20
DragonFlyBSD or OpenBSD for example because GNUstep install  scheme is =20=

particular (not relying on Unix filesystem layout) moreover theses OS =20=

are using special GCC version, custom filesystem layout etc.

At some point I could need build support on Windows too but not very =20
soon at least :-).

hmm=85
My current workaround would be a wrapper shell script driving pmk =20
process :
- dumping env variables I'm need in a special file
- running pmk which would parse this special file
- returning results
=85 but I would appreciate a better/simpler solution.

Quentin.
