Sigh, I had hoped that I'd finally reached the point of giving advice to newbies, but alas, I find myself asking for it again.

I am attempting to install NDISWrapper on FC5 system (dual booted with XP). I keep getting the same error, which the internet has generally confirmed to mean that I need to update my kernel and/or install the appropriate sources.

How do I do this? I've tried two different yum commands for each, I've downloaded and installed rpm's, and still "rpm -r" spits out the kernel version FC5 shipped with, and the sources still aren't being found.

I just finished a LFS project, and I found it easier to compile and install from source. Is that still a viable option on an rpm-based distro?

I don't wish to waste your time, but if someone could please just pass me a link to a page explaining this? Thanks.

BTW. I should note that there are folders with every kernel's name on it on the computer.

Certainly. You can compile a custom kernel on any distro.

I've only been usring Fedora for a few days but had to deal with kernel source alrady. Based on my experience I would say do the following:

yum update kernel
yum install kernel-devel
reboot with new kernel
go into /usr/src/kernels/$KERNELVERSION (<--variable for kernel version)
Do a "make oldconfig"
Then "make menuconfig", dont't stay in this just exit out and select yes for save. This should build your kernel header dependencies(I've found that drivers and the like require this when building from source.)

Then try to rebuild ndiswrapper.
