I was doing the NeHe tutorials on Debian Unstable back when it still used XF86. I only went as far as Tutorial 6 before I was bogged down with other things. Now I'm looking to pick them back up on my new laptop running Ubuntu "Hoary" and download lesson 1 linux/glx for review. However when I use the make command I get this output:

gcc -Wall -pedantic -ansi lesson01.c -o lesson01 -L/usr/X11R6/lib -lGL -lGLU -lXxf86vm

Any Suggestions?

It seems to be a problem with the pthread library; have you (correctly) installed pthread dev libraries? If you have installed them manually(configure, make, make install) check that the installation path is in the LD_LIBRARY_PATH environment variable and if it isn't so update that variable or the configuration file ld.so.conf

A better look to your command line showed me that you haven't included the pthread library, to do this add -lpthread to the command line; this should fix it...obviously you have to have the library installed in your machine (search pthread-dev with synaptic)

I fixed the problem. I didn't have nvidia-glx-dev installed under ubuntu, just the nvidia-glx package. Sorry to bother you, but I guess that's what happens when you're bouncing between programming and sleep.

Thanks everyone.
