Re: With gcc & with Eclipse

[Anne van Rossum]

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
