I downloaded nehe tutorial19. It compiled, linked and ran ok, but very slow since NVidia drivers were not installed.
I installed nvidia drivers but now the tutorial doesn’t link anymore, why??
Here are part of linking result:
gcc -Wall -pedantic -ansi lesson19.c -o lesson19 -L/usr/X11R6/lib -lGL -lGLU -lXxf86vm
/tmp/cc6ZuAGu.o: In function killGLWindow': /tmp/cc6ZuAGu.o(.text+0x15de): undefined reference to XCloseDisplay’

/tmp/cc6ZuAGu.o(.text+0x1ab8): undefined reference to `XGetGeometry’
It seems that every undefined references are to every X* function.
What do I need to install?
didn’t help. Installed all nvidia-drivers again. but no
If someone knows what causes these linking errors, please help:

Run ‘make’ as root in the NVIDIA_GLX-1.0-2313 folder. This will clean up DRI and properly install nvidia’s proprietary libs. You have stale files from DRI (you’re linking against a GL static library from DRI).
