hi @ all
I considered switching to LFS a while ago as this would be the only
Linux "distribution" fulfilling my requirements (besides Gentoo, of course).
So when reading the LFS Book there was a warning saying
Quote from LFS Book 6.2:
>> Some kernel documentation recommends creating a symlink from
/usr/src/linux pointing to
>> the kernel source directory. This is specific to kernels prior to
the 2.6 series and must not be created
>> on an LFS system as it can cause problems for packages you may wish
to build once your base LFS
>> system is complete.
The Gentoo Documentation however says:
Quote from http://www.gentoo.org/doc/en/kernel-upgrade.xml
>> Gentoo requires that the /usr/src/linux symbolic link points to the
sources of the kernel you are running.
Quote from http://www.gentoo.org/doc/en/alsa-guide.xml
>> Note: The above example assumes that /usr/src/linux symlink points
to the kernel sources you want to use. Please ensure the same before
proceeding.
But the $KERNEL_DIR/README says:
Quote from $KERNEL_DIR/README
>> Do NOT use the /usr/src/linux area! This area has a (usually
incomplete) set of kernel headers that are used by the library header files.
>> They should match the library, and not get messed up by whatever the
kernel-du-jour happens to be.
So after reading this I searched groups.google.com and the forums about
this issue and found a different approach, which can be used instead of
the /usr/src/linux symlink.
It's as follows:
In /etc/profile
Set $KERNEL_DIR to /kernel/src/current (symlink)
Set $KBUILD_OUTPUT to /dir/to/store/output/files
So what's the best way and _why_?
Does it even matter?
Cheers,
Jay
