How to compile an objective c program under windows with independant MingW

问题

I know how to compile the objective c program using gnustep version of mingw.

But I don't like their shell and I want to use the standard mingw gcc compiler.

I put this gcc bin directory in environment path of course, open command prompt in my helloworld.m directory

#import <Foundation/Foundation.h> 
int main (int argc, const char * argv[])
{
  NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
  NSLog (@"Hello World!");
  [pool drain];
  return 0;
}

and type

gcc -o hello hello.m -I /GNUstep/System/Library/Headers -L /GNUstep/System/Library/Libraries -lobjc -lgnustep-base -fconstant-string-class=NSConstantString

but it doesn't work because it cannot find foundation/foundation.h

How to fix this and if possible avoid hardcoding in hello source code ?

回答1:

Have a look here at the end of the post the blogger says to write:

gcc `gnustep-config --objc-flags` -o hello2 hello2.m -L /GNUstep/System/Library/Libraries -lobjc -lgnustep-base

It seems like you always have to pass through GNUStep

I had the same problem.Modifying command line like below solved my problem.

gcc -I"c:/GNUstep/GNUstep/System/Library/Headers" -L "c:/GNUstep/GNUstep/System/Library/Libraries" -o hello hello.m -lobjc -lgnustep-base -fconstant-string-class=NSConstantString
