1. One line summary of the problem:
kernel 2.3.99-pre5 does not compile without system-wide kernel headers
2. Full description of the problem/report:
I have removed the kernel headers (/usr/include/linux and
/usr/include/asm symlinks) from my Linux system. The goal is to compile
multiple kernel versions without having to update the symlinks each
time.
When I try to compile (make bzImage) the 2.3.99-pre5 kernel in this
environment, it fails with the following error message :
[root@xroms linux]# make bzImage
gcc -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -o
scripts/split-include scripts/split-include.c
In file included from /usr/include/errno.h:36,
from scripts/split-include.c:26:
/usr/include/bits/errno.h:25: linux/errno.h: No such file or directory
make: *** [scripts/split-include] Error 1
[root@xroms linux]#
In fact the split-include.c program needs to access one of the linux
headers and does not find it in my case.
3. Workaround
I have added the '-Iinclude' directive in the 'split-include.c' compile
rule (end of the root Makefile). See patch below.
NOTE : This fix does not alter the whole kernel.
