1. ls -l /lib/modules/2.4.19/build tells me tha no file or directory found. But I do have a /lib/modules/2.4.19 directory just no build in it.
2. I was running kernel 2.4.19 when I compiled it for the second time.
3. I thought this would do the trick: make install SYSINCLUDE=/usr/src/2.4.19 (that's where my kernel 2.4.19 source is)
but I got the same error with this.
The error that I get every time is: unresolved symbols in /lib/modules/2.4.19/video/NVidia
