Questions about compiling kernel on archlinux

Question

hi...i'm new of this forum and new of archlinux
i'm tryng to compiling a custom kernel in order not to replace the kernel26 package.. i prefere to make it with abs for managing it with pacman.. i followed the wiki but something went wrong.... i used both the pkgbuild i found on the wiki but nothing...can someone help me please??

Answer 1

if it can be of any help, this works for me too. actually, it's the official arch kernel PKGBUILD (maybe not the latest one) that I've just changed according to my needs:

just replace all the kernel26mm by kernel26mycustomkernelname. same below with the install file and of course in your kernel config.
