Linking opengl on linux

[dovkruger]

I've been using Mesa-5.1 on Redhat 9, which works, but it's slow. Now that I realized that I'm not using the opengl libs, I'm trying to link. I use the command:

g++ -Wall -march=i686 -g -I /usr/share/doc/NVIDIA_GLX-1.0/include/ -o Dov2b -L /usr/lib -L /usr/X11R6/lib -L/usr/local/lib Dov2.cc -lGL -lGLU -lglut

/usr/local/lib/libglut.so: undefined reference to `XGetExtensionVersion'
/usr/local/lib/libglut.so: undefined reference to `XFreeDeviceList'

... etc.

I have tried looking for these symbols in both header files and libraries but can't find them.

A related issue is that I can't seem to build libglut, so I am using one that may be part of Mesa.
Can anyone help, please?

thanks,
Dov

You link to gl, glut and glu but you don't link to X11 (you merely add the dir to your link path), try adding -lX11 . I'm surprised you missed so few symbols. Have a look at the link line that the GLUT examples & other makefiles spit out. AFAIK Mesa can emulate GLX in software so that's probably why you got away with it.

The linux forum is a better place to ask this stuff since they'll be a lot more familiar. Your next question might be (depending on your hardware & setup) how to get hardware acceleration through the DRI running correctly because you're still in software despite using the standard ABI :-). So that's where you should ask it if you need to.

There is a bug in the GLUT library shipped with RedHat 9, look in the linux forum for the work around.
