Bug 250302 – media-sound/xfi-drivers: kernel sources accessed through /lib/modules/`uname -r`

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Diego Elio Pettenò (RETIRED) 2008-12-08 16:33:57 UTC]

This bug is being reported because this ebuild is currently trying to build against the kernel tree by accessing it through /lib/modules/`uname -r` instead than through /usr/src/linux like it should.

This is bad in many situations, like:

- livecd installs: the running kernel is the one from the livecd and is most
likely not the same the user is installing to;
- livecd chroot fixes: as above;
- generic chroot: running kernel comes from outside, as above;
- kernel updates: users most likely would want their system to have all the
modules ready _before_ restarting.

Please fix your ebuild to use /usr/src/linux.

Thanks,
Diego

suggestion on how to use '/usr/src/linux'
2 problems im having are:

 - http://linuxmafia.com/faq/Kernel/usr-src-linux-symlink.html
 (linus commenting on the use of /usr/src/linux)
 - stripping the 'linux-' prefix from /usr/src/linux symlink

MY_KV=`readlink /usr/src/linux` # read '/usr/src/linux' symbolic link
MY_KV=${MY_KV:6}                # strip 'linux-' prefix

sed -r -i       -e 's/KERNELDIR/KERNEL_DIR/g' \
                -e 's/CFLAGS/EXTRA_CFLAGS/g' \
                -e 's/\$\(shell uname -r\)/'$MY_KV'/g' \
                -e 's/`uname -r`/'$MY_KV'/' \
                Makefile

I'm pretty sure we have to use one of the kernel eclasses to get this fixed 'properly'. I'll add the QACanFix to Keywords because I'm busy doing .NET stuff presently.
