| |
The following set of patches introduce support for separate output directory when building a kernel. Typical usage is building several kernels with different configurations - but based on the same kernel src.
Consider the following setup: /home/sam/bk/linux-2.6 <= kernel src
/home/sam/kernel/mars <= My workstation /home/sam/kernel/defconfig <= defconfig for compiletime testing
Then in order to handle the two different configurations I just have to do: cd /home/sam/bk/linux-2.6 make O=../../kernel/mars
And the same for the defconfig version.
All output files are stored in the output directory, including .config. [Thanks to Roman Zippel which made this loong time ago in kconfig].
The patch has been in existence in several months but only lately becoming in a suitable state ready for inclusion. It is developed based on an initial concept made by Kai Germaschewski, but refined a lot since then. It works with a kernel based on default configuration (make defconfig).
It is divided up in the following parts: core the kbuild changes to support separate output directory ieee Fix in ieee Makefile i386 Fix in i386 Makefiles + new syntax enabled for always This was required because i386 had an executable located in a subdirectory. include Fixes for errornous include paths, and one place where a generated .c file references a .h file in the kernel tree.
