Kernel Module Compilation

[Fujitus]

Hi All, I would like to compile my own kernel module but i'got a problems.

I try different way to compile the module on 4.1.20.1-ARCH kernel version, but each time it's tell me that the build directory in the kernel dosn't existe

make -C /lib/modules/4.1.20-1-ARCH/build SUBDIRS=/root KBUILD_VERBOSE=0 modules
make[1]: *** /lib/modules/4.1.20-1-ARCH/build: No such file or directory. Stop.
Makefile:11: recipe for target 'all' failed
make: *** [all] Error 2

So I try to import the build envirement with rpi-source but gcc is not in the extract version that rpi-source need.

gcc version check failed: could not extract version numbers
Skip this check with --skip-gcc

Rpi-source need gcc-4.8 but it's not on AUR

If some one got a idea let me know

Don't know if this will help - but when ever I've been playing with enabling additional kernel functionality, either as modules, or in the core code, is to compile the kernel from scratch. E.g. I downloaded the latest linux kernel and built from that.

Now I've never done this on arm (well have a cross compiler on my home computer, for developing OS ideas on a panda board), and native kernel compilation on arm would be painful (I'm guessing 24h compilation time wouldn't be unusual).

I guess you should be able to down load the source package on arch (probably going via aur); then there is hope in that of just compiling a module, which *should* be compatible with the kernel (assuming what is in aur is the same as mainline).

So guess this won't be much help. Do keep plugging away though ...
