Who's directions did you follow, from farslayer or mine? Shouldn't make a difference, basically we're saying the same thing.
What you have are the kernel-headers. Useful on your system, but you really need the full sources. Let's help you step by step.
First, open a commandprompt, become root with the su command and type
This gives you the versionnumber of the running kernel. Still on the commandline, continue with
Code:
apt-get update && apt-get install kernel-source-<version>
Substitute <version> with the
exact number you got from the uname command. Apt may come up with dependencies, answer affirmative. Let it 'do it's thing'.
Next, cd to the /usr/src directory. If all went well, an ls command should show you the source package. Now, untar the package with
Code:
tar -xjf kernel-source-<version>
That unpacks the sources in a new directory. Enter that directory with cd (use tab-completion: cd li<tab> will most likely do)
Now is a good time to figure out all you can from your hardware, 'cause you have to configure the kernel. Choose either make menuconfig (requires the ncurses dev packages) or make xconfig (requires Qt, in general already available on your system) If you don't know what to do next, save the default configuration and exit the program. You're still on the commandline, do
Code:
make && make modules && make modules_install && make install
This will take the better part of a few hours (depending on your hardware)
Don't dispair, we're nearly done! After the previous command finishes you'll have to make a symbolic link from where the sources are installed to the /usr/src/linux directory. You do that with
Code:
ln -s /usr/src/linux /usr/src/kernel-source-<version>
Done!
Good luck!
