Im running FC4, and I recently treid to update the kernel to a 16 stack version from Linuxant so my computer wouldnt freezez every two minutes while ndiswrapper was running.

The install went fine. My problem is now with the kernel source. Whenever I try to compile a program, it tells me there is no source located in the given directory (lib/modules/... or something, I cant access the interent from my computer, so bear with me please).

To remedy this, I downloaded the source tarball from Linuxant and extraacted it into the given dir, but I get the same error. Is there something I need to do with the source?

Err, bump.

it probably wants the kernel source, not the linuxants source. Install the kernel source using rpm tools. I don't quite remember how fedora name this but it is probably "kernel-source-x.x.x" or "linux-source-x.x.x" or something similar. Do a search
