 From /usr/doc/opengl-1.1.0/README.txt:


Linking of code calling OpenGL, GLU, GLUT
-----------------------------------------

Add -lglut32 -lglu32 -lopengl32 to your link command.
                      ^^^^^^^^^^

GetPixelFormat is not a fonction in OpenGL. Use wglGetPixelFormat.

P.S. Maybe I'll write a perl script for that :-)

Problem with opengl.dll

[Axel Kowald]

Hello everybody,

I recently installed the latest Cygwin on my NT machine and tried to
port a program which uses openGL. It built without problems but when I
run it complained that it couldn't find opengl.dll. I had a look and
found an opengl32.dll in my winnt/system32 folder. I simply renamed it
and tried again. Now the program complains that it can't find the entry
point for "GetPixelFormat" in opengl.dll

Obviously I'm doing something wrong :-(
Is opengl32.dll actually a different library from opengl.dll, and if yes
where can I get it ? Could it be a version problem, because the program
I try to compile is already 2-3 years old ?

Any hints are welcomed.


	Axel Kowald
