Ahh, I bet it's due to the monolithic build, I always use multilib.
I'm not sure what the difference (advantage?) is or even what gets put
into the monolithic build.

Then just set wxUSE_OPENGL 0 and wxUSE_GLCANVAS 0. I don't fully
understand what wxUSE_OPENGL is for (appears only in Linux version of
wxWidgets as far as I can tell) as it is not used in any header. wxLua
checks for wxUSE_GLCANVAS since that's used in the wxWidgets
glcanvas.h header. You also have to remove the linker command
-lwxlua_msw28_wxbindgl since I don't think we can be clever enough to
put a check in the makefile.gcc.

Another option is to set wxLUA_USE_wxGLCanvas 0 in
modules/wxbind/setup/wxluasetup.h and none of the gl code will be
compiled. This is probably the easiest way.

Could you tell me what libs are in your wxWidgets/lib dir? As I am
unfamiliar with the monolithic build, I'd be interested to know what
gets output using the command you have above for wxWidgets.
