[solved] building the kernel headers for custom kernels

eldragon · 2010-04-01 12:44:33

well, ive been building several different kernels for my laptop, so that i can test stuff. but ive got a problem with the kernel headers.

ive mirrored the arch kernel's PKGBUILD and modified some naming to get a custom kernel. but when i try to build a custmo module, it complains the headers are broken. (example, vbox_build_module).

im pasting the pkgbuild here for future reference...if someone sees something thats plain wrong, please say so.
thanks

Check out the kernel26-ck package in the aur, that doesnt have that problem.

ngoonee · 2010-04-01 23:36:31

That PKGBUILD should produce 2 packages, does it?

yes it does, and i do install both.

gotta check the aur ck kernel package to see what im missing. i managed to get a working one which has identical headers sub package (except for the name),

i can build the vbox modules with that kernel, but not with the one i posted here (???)

ngoonee · 2010-04-02 06:09:02

Check out this line

for i in acpi asm-{generic,x86} config linux math-emu media net pcmcia scsi sound trace video; do

for anything that might be missing. The error message when compiling would give you more of a clue. Off-hand, you may need to add 'generated', as I recall I needed that when the kernel moved to 2.6.33.

Problem with vbox_build_module after Kernel update.

Would you care to elaborate for us less versed in "Linux Geek" skills?

Thanks.......

What about Ctrl-F skills? There's a line like that in the PKGBUILD for your custom kernel. You may need to add 'generated'.
