problem with libraries

[Thanasis Petridis]

Hello. My name is Thanasis.

First of all sorry for my poor english.

Secondly, if this is the wrong mailing list or if there is a solution for my problem, just tell me which is the correct mailing list or where is the answer.

I have a PC running on Windows 7 and I want to start programming apps for iOS. So I figured out that I should start from learning the Objective-C language.

So I searched in the Internet and I found that I can program Objective-C on windows 7 through GNUstep. I install in the directory c:\GNUstep the following 3 setups

-gnustep-msys-system-0.28.1-setup

-gnustep-core-0.28.0-setup

-gnustep-devel-1.3.0-setup

I have created a file hello.m in the folder c:\new 

I started the shell application

I wrote c:\new

and then I wrote g++ hello.m and I get the error " Foundation.h: No such file or directory compilation terminated"

I changed the path of Foundation in the source code of my program to the correct 

" #import <C:\GNUstep\GNUstep\System\Library\Headers\Foundation\Foundation.h> "

and then I get the error : " C:\GNUstep\GNUstep\System\Library\Headers\Foundation\Foundation.h:30:40: fatal error: GNUstepBase/GSVersionMacros.h: No such file or directory "

I changed the path of the GSVersionMacros.h inside the source code of the Foundation.h file and then I got a new error for another header file inside the GSVersionMacros.h file.

How can I fix this? Should I have to do this for all the header files? 

Thank you very much.
