Hi,
you are trying to write a pure obj-c file, without gnustep, when you use
objc.h.
Instead, when you use Foundation.h, you are accessing the Foundation,
part of Openstep /Cocoa.
For the latter, the most convenient way is to write and use a gnustep
makefile. Everything is set up for you already then. Please try with
that, so you get hands on. Afterwards, if you feel the need to strip
down, you may try yourself the hassle of setting up everything for
yourself. But, honestly, it is not worth the trouble usually.
For a command line program (like hello world) use "Tool" as a reference.
Check here:
http://wiki.gnustep.org/index.php/Writing_Makefiles
and the releated gnustep make reference.
Especially http://www.gnustep.it/nicola/Tutorials/WritingMakefiles/ will
be of use for you!

Hello everyone!
I am a noob in GNUstep and I am trying to compile my first
objective-c file.
This is going to be a quite long email, since I will try to describe
in as many details as I can the installation process I did.
I am using a Windows environment, so I downloaded GNUstep MSYS
System version 0.29.0 and installed, with default path, in my
computer. After that, I installed GNUstep Core version 0.29.0, with
default configurations as well. Just to be on the safe side, I
installed, then, GNUstep Devel version 1.4.0, with default
configurations too.
Then I went to the Start menu and launched the Shell software. After
that, I decided it was better to test the install, I wrote the
following code:
#include <stdio.h>
//Now, testing the Objective-c libraries.
#include <objc/objc.h>
int main (void)
{
prinf("All right and ready to go!");
return(0);
}
And I got an error saying "objc/objc.h: No such file or directory".
I tried with "#include <Foundation/Foundation.h>" as well and I got
the same error, just with instead "objc/objc.h" it was written
"Foundation/Foundation.h".
Then, I tried to find the header files inside GNUstep and could not
find it. After some exploration, I found that my / folder is under
C:\GNUstep\msys\1.0\ and the headers are under
C:\GNUstep\GNUstep\System\Library\Headers\objc, so I have no
visibility to objc.h, Foundation.h or any other header, so I can't use
any arguments to show gcc where to look for the files.
Do anyone know what can I do to solve my problem? I am sorry to have
made such an enourmous email, but I am trying to compile my code for
quite a while now and looking around for the solution of my problem
without result, and been getting increasingly frustrated.
Looking forward to hear from anyone.
