In your previous post you had the problem thet libglut32.a had not
been found by the linker. The above output shows that this problem
is solved by the change of name (-llibglut32 -> -lglut32).

However now you get honest undefined references which in turn means
the library does not provide the functions you are using (from the
linker point of view).

I don't know libglut32.a but I'd suspect either the corresponding
header use the wrong declarations or the (import?) library does
use the wrong naming (e.g. one too many leading '_', stdcall when
it shouldn't or whatever).

Googleing for 'libglut32\.a' does provide this URL:
