undefined reference to `_WinMain@16' error!

[jchiarelli]

Hi ,
I am on windows trying to compile some object-c code usign GNUstep.

I am getting the following eror:

$ make
This is gnustep-make 2.0.7. Type 'make print-gnustep-make-help' for help.
Making all for tool test...
 Linking tool test ...
C:/GNUstep/mingw/bin/../lib/gcc/mingw32/3.4.5/../../../libmingw32.a(main.o):
main
.c:(.text+0xbd): undefined reference to `_WinMain@16'
collect2: ld returned 1 exit status
make[1]: *** [obj/test.exe] Error 1
make: *** [test.all.tool.variables] Error 2



My make file is basic:


include $(GNUSTEP_MAKEFILES)/common.make

TOOL_NAME = test
LogTest_OBJC_FILES = test.m

include $(GNUSTEP_MAKEFILES)/tool.make


 
 
 
 
For reference my code is:
