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

nice.

Anyways, here is what I added to and changed in the gnustep-gears
makefile:

Gears_TOOL_LIBS += -lopengl32
LDFLAGS=-lopengl32

I understand the LDFLAGS option, but could someone explain the first
change?  My background is in C (PalmOS), VC++, and C# (not gcc) and
the construction of that line isn't clear to me.

Again, thanks in advance,
Doug.
