Compiling kernel modules from source: prerequisites.

To compile a kernel module from source you need:

1. to boot into the kernel you want to compile against.
2. install kernel headers for the current kernel
3. a symlink '/usr/src/linux' pointing to the currently installed kernel headers.

Installing the kernel headers manually is not sufficient, because that does not create the necessary symlink.

To accomplish 2 and 3, the easiest way I know of is:

sudo apt-get install module-assistant

sudo m-a prepare

the last command will provide both 2 and 3.

Hope this helps someone,

Happy crunching

+1 for this one.  Kernel compiling is a tricky subject, and you're inviting untold questions from a lot of folks regarding the "fun" that can occur with taking control of how things work at a deeper level.  Thanks for sharing the easy-track to setting up symlinks.
