Re: Foundation import file not found

[Johannes Brakensiek]

Hi Peter,

I am currently discovering the ways of building stuff with GNUstep as 
well. ;)

The most important thing to start correctly is to make sure to have all 
compiler/linker flags and environment variables set. The easiest way to 
do this is to source (not execute) the corresponding GNUstep.sh file, 
which might work as this using Ubuntu:

. /usr/GNUstep/System/Library/Makefiles/GNUstep.sh

You might even want to add execute this to add the line above to your 
bashrc:

echo ". /usr/GNUstep/System/Library/Makefiles/GNUstep.sh" >> ~/.bashrc

For a reference on how to build a simple Objective C app by either using 
the command or a make file you might look at this demo from Patryk 
Laurent:

https://github.com/plaurent/gnustep-build/blob/master/demo.sh#L134

Of course there clang is used so handling might differ a little bit when 
using gcc. But in general I think gnustep-config should output the 
correct flags when set up with gcc.

Hope that helps,
Johannes
