Re: GNUStep OpenGL on WinXP

Hi Doug

you should try

 make messages=yes

to view the compiler and linker command lines and check how they  
change when you add/remove these GNUmakefile options. ;-)

Since you specify -lopengl32 twice (as Gears_TOOL_LIBS and LDFLAGS)  
I'd expect it to appear twice on the linker command line;
maybe one of the two is redundant ? (eg, try removing the LDFLAGS line  
and see if it still works) ;-)

As a general background of what the two options do, setting LDFLAGS  
will generally force the -lopengl32 to appear on the linker command  
line,
in a certain position, for everything that gets compiled (in your  
case, only the Gears application, but could be more if you had more).
Gears_TOOL_LIBS will do the same, but IIRC in a different position on  
the linker command line, and only for the 'Gears' instance - in your  
case
the Gears application.

Thanks
