Using custom kernel

Hi All,

I would like to use buildroot with a custom kernel. We have the kernel source we want to use checked into cvs, rather than downloading it from the net.

Is this currently possible with buildroot? If so where should I look? If I have to try to customise buildroot myself any suggestions on where to get started?

Many thanks,

Will.

Hi Will,

(Apologies for the delayed reply; I'm only catching up on the list now after a recent vacation.)

I've done something similar here, though it's messy.
I added a new directory target/linux-xyz, with my whole kernel source tree checked into target/linux-xyz/2.6.15-uc0.

The kernel source tree supports building into a separate objects directory, which I have located in project_build_<arch>/<project> as per standard buildroot practice.

Building out-of-tree modules is even more messy, because now you have kernel source in one place, kernel objects (including the include/asm symlink and the include/linux/autoconf.h file) in a second place, and module binaries going a third place again. But it's workable.

A simpler solution would be to copy the kernel source into project_build_<arch>/<project> and build it in-tree. However that isn't very good for development, unless you can rig up some complicated dependencies between the original source and the copy.

I can share a patch if it would be useful.
