Re: With gcc & with Eclipse

Thanks ... that's a very good trick :-)

By the way with the current gnustep-make from trunk, you can also do:

 * make sure GNUstep's appropriate dirs are added to your PATH and
ld.so.conf [or equivalent to ld.so.conf on your system]

(ie, something like
PATH="$PATH:/usr/GNUstep/System/Tools:/usr/GNUstep/Local/Tools" and adding
/usr/GNUstep/System/Library/Libraries and
/usr/GNUstep/Local/Library/Libraries to your ld.so.conf and rerunning
ldconfig regularly)

 * set the GNUSTEP_MAKEFILES environment variable (it should be set to
something like  /usr/GNUstep/System/Library/Makefiles/)

And then 'make' should work. ;-)

All the other variables are then read automatically by gnustep-make from
the GNUstep config file in /etc/GNUstep/GNUstep.conf. :-)

Thanks

Dear members,

For anyone who want to run Objective-C code and to use Eclipse I
recommend the following approach:
- Create sample.m file and GNUmakefile in ObjCProjectExample
- run $GNUstep root/System/Library/Makefiles/GNUstep.sh
- make (that should go fine)
- start eclipse from same console (building/running should go fine)
- add new C project and import directory structure (from
ObjCProjectExample)
- at Project - Properties - C/C++ Make Project - [tab] Environment push
button Select
- select all environment variables with GNUstep in their names
- apply changes

(Re)Starting Eclipse from whatever location should be fine now. The
GNUstep.sh shell script is no longer needed.

Kind regards,

Anne
