These .lib are not for linking with Cygwin's g++; don't use them. Instead, 
link with -lglut32 -lglu32 -lopengl32 . This is explained in the README.txt 
file in /usr/doc/opengl-1.1.0 .

WIN32 definition and/or -mwin32 are not necessary for Glut programs.

You need WIN32 defined for the proper declarations
to be picked up from many header files

easiest to do by adding -mwin32 to the compiler flags

glut Problems...

[Patrick Reuter]

Hi,

I have reinstalled cygwin recently.

Before, I never had problems with the glut library, but now using the
following compilation command:

g++ -pg -O2 -Wall -g    main.o .........  -o a.out
//w/lib/NT/opengl32.lib //w/lib/NT/glu32.lib //w/lib/NT/glut32.lib

the linker doesn't find the glut references anymore:

undefinded reference to 'glutMainLoop()' etc.

Can anybody help me?

Thanx in advance!

Patrick
