[Mingw-users] Can't find -lGL with MingGW

[Darrell B. <dar...@ed...>]

I've just installed Msys and Mingw in Windows because I'm wanting to 
port my SDL game to Windows. I installed Msys and Mingw as normal and 
added mingw to my msys fstab and then I untarred the SDL source did 
"./configure --prefix=/mingw && make && make modules install".

I can compile normal SDL programs fine but when it comes to a program 
using OpenGL I get an error like "Can't find -LGL" or "Can't find -GL". 
I'm compiling the program like "g++ program.cpp -o program -lGL -lGLU 
`sdl-config --cflags --libs`". I know normally that this mean I havn't 
got the OpenGL libraries or headers installed but in /usr/include/GL 
there exists gl.h, glu.h and glext.h so I know it's not the headers. 
I've had a look for libgl.so which is what I think the file I need is 
but I can't find it. In /usr/lib there are lots of .a files one of which 
I believe is libglext.a or something like that but there isn't a libgl.a.

Any ideas?
