Re: Using VC-compiled Mesa binaries under Cygwin

Well, no. Building Mesa with glut creates the following files (which I have 
copied to the directory of the simple test program I trying to build with 
compiler supplied with Cygwin using the Makefile in first post):
$ ls *.DLL *.lib
GLU32.DLL*  GLU32.lib*  GLUT32.DLL*  GLUT32.lib*  OPENGL32.DLL* 
OPENGL32.lib*

I tried renaming GLUT32.DLL to libglut32.dll.a, but the linker still cannot 
find the definitions of any glut functions. I tried adding GLUT32.lib with 
the objects in the linking stage, but still no go.
However, doing a nm GLUT32.lib | grep glutPostRedisplay (the first undefined 
reference), shows:
$ nm GLUT32.lib | grep _glutPostRedisplay
00000000 I __imp__glutPostRedisplay@0
00000000 T _glutPostRedisplay@0

Any ideas? And one more thing: Please don't quote raw email addresses when 
replying to this list. Thanks.
