[gentoo-user] Unable to calculate Linux Kernel version [New Thread]

[gentoo-user] Unable to calculate Linux Kernel version [New Thread]

[Bogo Mipps]

Hi - have re-compiled as indicated, but it hasn't helped.  Now running 
2.6.12-gentoo-r10 without problems, but still have the previous error on 
*some* ebuilds i.e. svgalib & lm_sensors.  

As established earlier correct links are all in place, the correct .config is 
in the source, directory, as is Makefile - and /include/linux/verion.h 
exists. 

I have googled extensively, including gentoo forums, where similar errors have 
been produced, but nothing suggested solved my problem.  Most were related to 
non-existent .config and/or Makefile.  

Following is the error message:
<snip>
!!! ERROR: media-libs/svgalib-1.9.21-r1 failed.
!!! Function linux-info_pkg_setup, Line 526, Exitcode 1
!!! Unable to calculate Linux Kernel version
<snip>

When I look at Line 526 in /usr/portage/eclass/linux-info.eclass I find the 
following:

<snip>
525    linux-info_pkg_setup() {
526    get_version || die "Unable to calculate Linux Kernel version"
527    [ -n "${CONFIG_CHECK}" ] && check_extra_config;
<snip>

>From here on in - I'm struggling with bash and can't make sense of it:  any 
pointers would be appreciated.

Hi,
Check to make sure that "/usr/src/linux" link point to your
current/working kernel. svgalib depends on kernel link to build.

Sorry this was covered in the earlier thread, should have covered it again.

Re: [gentoo-user] Unable to calculate Linux Kernel version [New Thread]

[Glenn Enright]

Try this...

	ls -l /usr/src/linux
	uname -r

these should give you the same version. If not you need to adjust the linux 
symlink to reflect the kernel version you are running. Then

	cd /usr/src/linux
	cp /boot/config-$(uname -r) ./
	make oldconfig && make

Now you should be able to do the emerges you wanted to. The point is to have 
your source tree in working condition, and findable, as opposed to clean.

If you run different kernel versions often, try adding a few lines 
to /etc/conf.d/ like

# -- quick hack to ease work of updating kernels and make emerges consistent
#
ebegin "Refreshing kernel source link to running kernel."
rm -f /usr/src/linux
if ! ln -s /usr/src/linux-$(uname -r) /usr/src/linux
then
        ewarn "   Bugger ... could not update. Please manually create the"
        ewarn "   symbolic link '/usr/src/linux' to the running kernel 
source."
        ewend 1

rugosa / # ls -l /usr/src/linux
lrwxrwxrwx  1 root root 23 Oct  3 14:22 /usr/src/linux -> 
linux-2.6.12-gentoo-r10

rugosa / # uname -r
2.6.12-gentoo-r10
rugosa / #    

This looks ok?  Yes?

So where to from there?  No point in the "If not"?

TIA

You still need to make sure the sources are 'bedded in' as it were, so perform 
the stuff described in the second part of my post as well.

Done, and there is an improvement in the error code at least: 

* Determining the location of the kernel source code
 * Found kernel source directory:
 *     /usr/src/linux
 * Found kernel object directory:
 *     /tmp/kernel
 * Found sources for kernel version:
 *     2.6.12-gentoo-r10

 * getfilevar requires 2 variables, with the second a valid file.
 *    getfilevar <VARIABLE> <CONFIGFILE>
 * Could not find a usable .config in the kernel source directory.
 * Please ensure that /usr/src/linux points to a configured set of Linux 
sources.
 * If you are using KBUILD_OUTPUT, please set the environment var so that
 * it points to the necessary object directory so that it might find .config.

Why would the .config that's in the directory not be usable?  I just did the 
make oldconfig && make as you suggested - which ran without errors ...

I guess if I could read/understand bash I'd find out from "linux-info.eclass" 
what it wanted of .config - but that's where I come unstuck.

Bah! try
	cd /usr/src/linux
	make menuconfig
exit out of that and save in the process. Try the emerge again. Stupid 
software ;)

No, still the same error.  However I thought I'd try the following:

export KBUILD_OUTPUT=/usr/src/linux-2.6.12-gentoo-r10

- and then try the emerge svgalib again.  This time it emerged no problem.

Not very satisfactory, other than achieving the emerge.  Why/how am I using 
KBUILD_OUTPUT? (see above) Mystery to me.  Now I guess I get this every time 
an ebuild uses /usr/portage/eclass/linux-info.class - and it looks from 
bugzilla that more and more are moving over to it. 

And why only me?  Only clue I have is from gentoo forum where someone found a 
miscompiled coreutils [/bin/echo] was producing same error as I got above. He 
worked through the bash file and found that was the problem.  I recompiled 
coreutils in case (I'd had a bad memory stick earlier this year) but that 
didn't help.  Maybe eventually when everything on my box is 
upgraded/recompiled I'll get back to "normal".

Thanks.

Hi,
Just two suggestions: 1.re-emerge the kernel-source & try again or
2.try newer/older version of svgalib. Check the USE-flags & deps.
PS: assume you checked/run revdep-rebuild before and searched Bugzilla.

Did 1.  No help.  On 2. I succeeded with earlier version (didn't seem to be 
using linux-info.eclass)  Always run revdep-rebuild after every emerge. 
Searched Bugzilla - no exact same problem, but evident that linux-info.eclass 
will be used more and more so unless I get it sorted I'll always have to use 
the solution as per other post on this thread.

Many thanks anyway.
