Today I installed Red Hat 7.2 and downloaded the latest drivers from SoundForge for the Audigy card but I'm having some problems. I looked at other posts on here but was unable to resolve my problems. I followed the instructions that were included but when doing "make install" there's an error. When I do "modprobe emu10k1" I see the following problems:

Anyone know what the problem is?

All I know is that I am trying to install Nvidia drivers which looks very easy. However, I get the same type of error, that I am trying to load a non-gpl module and have unresolved symbols (exact error message as above). The readme said I might be pointing to the wrong kernel header files but I tried pointing directly to them using:
make install SYSINCLUDE=/lib/modules/linux-2.4.18/
and it still returned the same error.

Did you already compile a custom kernel or are you using the default RH installation kernel? If so you may want to compile a kernel first. If that doesnt work try editing the Makefile so it points to the kernel you want.
