Bug 65246 – sys-kernel/config-kernel-0.3.3 is not working

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description José Romildo Malaquias 2004-09-24 15:06:51 UTC]

I am having some issues when emerging app-misc/lirc-0.7.0_pre7-r1. I get the following messages:

 * /usr/src/linux is a symbolic link
 * Determining the real directory of the Linux kernel source code
 * Building for Linux 2.6.8-gentoo-r4 found in /usr/src/linux
 * which outputs to /usr/src/linux
 * By not using the kernel's ability to output to an alternative
 * directory, some external module builds may fail.
 * See <insert link to user doc here>
 * Due to the 2.6 kernel build system, external module compilation
 * with a normal setup requires write access to //usr/src/linux
 * There are several ways to fix/prevent this.
 * Users can willingly let portage make this writable by doing
 * # config-kernel --allow-writable yes
 * However, this is considered a security risk!
 *
 * The prefered method is to enable Gentoo's new 'koutput' method
 * for kernel modules. See the doc
 * http://www.gentoo.org/doc/en/2.6-koutput-user.xml
 * To enable this, you'll need to run
 * # config-kernel --output-dir /var/tmp/kernel-output
 * and then install a new kernel

After running the commands:

# emerge -uv config-kernel
# config-kernel --output-dir /var/tmp/kernel-output
# env-update
# source /etc/profile
# cd /usr/src/linux-2.6.8-gentoo-r4/
# make mrproper
# cd
# emerge --unmerge gentoo-dev-sources-2.6.8-r4
# emerge -uv gentoo-dev-sources
# cd /usr/src/linux-2.6.8-gentoo-r4/
# cp -vai /boot/config-2.6.8-gentoo-r4 .config
# make && make modules_install && make install
# cd
# LIRC_OPTS="--with-driver=pixelview_pro" emerge -uv lirc

lirc still does not build with the same message. Also, the kernel was no built in /var/tmp/kernel-output, but in /usr/src/linux-2.6.8-gentoo-r4.

Am I doing something wrong, or are there issues with config-kernel?

I've the same problem with lirc-0.7.0_pre7.

I installed config-kernel-0.3.3 too and ran :

#config-kernel --output-dir /var/tmp/kernel-output
 * Writing out changes to /etc/env.d/05kernel
 * Running env-update. You should run 'source /etc/profile' to update
 * your environment, or log out and in again.
 * Error updating the environment!

That's what I received.

The only change I noticed is :

# echo $KBUILD_OUTPUT_PREFIX
/var/tmp/kernel-output

[Comment 2 José Romildo Malaquias 2004-09-25 04:01:26 UTC]

I have forgot to tell that I have the same output messages from the command "config-kernel --output-dir /var/tmp/kernel-output".

[Comment 3 Arcila Thomas 2004-11-09 12:13:10 UTC]

It seems to me it's working (at least on my computer)
you only have to do
config-kernel --make-koutput=$PWD in your kernel dir

The only problem is that new kernel doesn't automagically use that feature.
--output-dir only sets KBUILD_OUTPUT_PREFIX which seems not to be used by any eclass.

[Comment 4 Peter Johanson (RETIRED) 2005-02-26 18:11:53 UTC]

config-kernel is no longer supported or recommended. Marking WONTFIX.
