Re: With gcc & with Eclipse

[Anne van Rossum]

Hi Tima,

Thanks for your response.

Sorry for eventual misunderstandings. In the console I can type "make"
at which time the GNUmakefile is used and the appropriate environment
(and other?) variables, and the thing compiles okay.

However, using a "gcc ..." command from the command line, I couldn't
make it work.

And more important, I have to set the appropriate environment variables,
etc. in Eclipse that can be coupled to the gcc compiler. For that I set
all the kind of stuff done in GNUstep.sh (that I have sourced indeed),
like the $GNUSTEP_..., $GNUSTEP_FLATTENED, $PATH, $CLASSPATH, $GUILE...,
just by copying the values from "env".

And yes I have the /System/Library/Headers/Foundation files. I hope you
can help me. I don't know exactly what is going on behind the scenes of
the shell scripts and GNUmakefile.

Kind regards,

Anne
