discuss-gnustep@ isn't bad either, I'd guess. If anything, more people follow it.

Hi all,

I mistakenly sent a request to the wrong list (discuss instead of help-gnustep). Here it is again on the probably more appropriate list:

I am trying to get gnustep-make-2.7.0 to work on MacOSX Sierra. After

./configure 
make
make install

and thus installing GNUstep make I try to build a minimal test app

main.m:
===================
int main (int argc, const char **argv, char** env)
{
   NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
   NSString *processName = [[NSProcessInfo processInfo] processName];
   Controller *controller;

   [NSApplication sharedApplication];
   NSImage *image = [NSImage imageNamed:[NSString stringWithFormat:@"address@hidden", processName]];
   if (image) [NSApp setApplicationIconImage:image];

   controller = [[Controller  alloc] init];
   [NSApp setDelegate:controller];
   
   [pool release];

   return NSApplicationMain (argc, argv);
}

Controller.m:
=====================
#import <AppKit/AppKit.h>
#import "Controller.h"

@implementation Controller
@end

and get

admins-iMac:Test ahoesch$ make messages=yes

I have also tried to build the app manually on the command line, now using clang instead of gcc and -arch i386 instead of -m32:

cd /Build/Test; \
/Library/GNUstep/Makefiles/mkinstalldirs ./obj/Test.obj/
/Library/GNUstep/Makefiles/mkinstalldirs /Build/Test/Test.app/Contents/MacOS


cd /Users/ahoesch/Development/Test

but still get the same error!?

I am clueless! This used to work on earlier versions of MacOSX. Any idea?

Thanks a lot in advance!!
