The TLDP guide is fine. The point is you cannot copy&paste their
Makefiles, because these will use "/lib/modules/$(shell uname
- -r/build" as the kernel build directory. This however refers to the
Linux kernel on your build machine, not the L4Linux one. Replace this
path with your L4Linux build dir, so that you build a kernel module
for L4Linux and not for your local machine.
