okay, got it to compile and work, find below contents of GNUmakefile;
GNUSTEP_MAKEFILES=/usr/local/GNUstep/System/Library/Makefiles
include $(GNUSTEP_MAKEFILES)/common.make
TOOL_NAME = mainapp
mainapp_OBJC_FILES = main.m
include $(GNUSTEP_MAKEFILES)/tool.make

put it in the same directory as main.m and just issue gmake.
remember to edit config.make found at;
/usr/local/GNUstep/System/Library/Makefiles/
to reflect the actual location of clang tools, i.e. /usr/bin/

best regards,
