Kernel source directory not found (SOLVED)

[lokoalex]

Im trying to

genkernel --menuconfig all

and this is what I get:

Code: Select all

* Gentoo Linux Genkernel; Version 3.4.8
* Running with options: all

* ERROR: kernel source directory "/usr/src/linux" was not found!

* -- Grepping log... --

* Please consult /var/log/genkernel.log for more information and any
* errors that were reported above.

* Report any genkernel bugs to bugs.gentoo.org and
* assign your bug to genkernel@gentoo.org. Please include
* as much information as you can in your bug report; attaching
* /var/log/genkernel.log so that your issue can be dealt with effectively.
*
* Please do *not* report compilation failures as genkernel bugs!

*

So I tried upgrading the kernel and I still get the same problems.
Any suggestions?

Is there a symlink /usr/src/linux to one of the real /usr/src/ kernel source directories?
If not, make one yourself.

[lokoalex]

Yes I have a symlink. Here is what I have:

Code: Select all

#ls -l /usr/src/linux
lrwxrwxrwx 1 root root 15 Nov  2 10:18 /usr/src/linux -> linux-2.6.22-r8

[lokoalex]

Still having the same problems. Is there anyone who can help?

[tarpman]

Does /usr/src/linux/linux-2.6.22-r8 exist? There is no sys-kernel/vanilla-sources-2.6.22-r8; the closest one to that is sys-kernel/gentoo-sources-2.6.22-r8, which would result in a target for the symlink of /usr/src/linux-2.6.22-gentoo-r8.

[lokoalex]

Here is what I have:

Code: Select all

cd /usr/src/linux
bash: cd: /usr/src/linux: No such file or directory

But:

Code: Select all

ls /usr/src
linux  linux-2.6.22-gentoo-r8  linux-2.6.22-gentoo-r9

And:

Code: Select all

ls /usr/src/linux
/usr/src/linux

But the output is blinking for some reason.

[Hu]

The blinking is an indication that ls considers the symlink to be broken. In this case, the link is dangling. According to your output, you have linux-2.6.22-gentoo-r8 and linux-2.6.22-gentoo-r9 as available kernel source directories. However, your symlink points to linux-2.6.22-r8. Notice that the kernel directories have a gentoo- that your symlink does not. To fix it, remove the symlink named linux and recreate it, this time pointing it to a directory that exists. You can use the shell's tab completion feature to ensure that you do not misspell the name.

[Lemmens]

But:

Code: Select all

ls /usr/src
linux  linux-2.6.22-gentoo-r8  linux-2.6.22-gentoo-r9

But the output is blinking for some reason.

You can use app-admin/eselect to modify the symlink (#emerge eselect).
The command eselect kernel list outputs the different kernel sources on your system and shows which one is currently selected by the symlink:

Code: Select all

Available kernel symlink targets:
          [1]     linux-2.6.22-gentoo-r8  *
          [2]     linux-2.6.22-gentoo-r9

Then you can select the one to which the symlink has to point to: "eselect kernel set 1" or "eselect kernel set 2"

[lokoalex]

Still having the same issues.

[lokoalex]

Ok so I checked my kernel version:

Code: Select all

# eselect kernel list
Available kernel symlink targets:
  [1]   linux-2.6.22-gentoo-r8 
  [2]   linux-2.6.22-gentoo-r9

And I selected the one i use:

Code: Select all

src # eselect kernel set linux-2.6.22-gentoo-r8

Then I checked to make sure it worked:

Code: Select all

# eselect kernel list
Available kernel symlink targets:
  [1]   linux-2.6.22-gentoo-r8* 
  [2]   linux-2.6.22-gentoo-r9

Then I created the new link:

Code: Select all

src # ln -sfn linux-2.6.22-gentoo-r8

Then I tried to:

Code: Select all

genkernel --menuconfig all 

And this is what I get which is the same as before:

Code: Select all

src # genkernel --menuconfig all
* Gentoo Linux Genkernel; Version 3.4.8
* Running with options: --menuconfig all

grep: /usr/src/linux/Makefile: No such file or directory

So I decided to check my symlink and its correct:

Code: Select all

src # ls -l /usr/src/linux
lrwxrwxrwx 1 root root 22 Nov  6 12:45 /usr/src/linux -> linux-2.6.22-gentoo-r8

And the output of this wasnt blinking anymore:

Code: Select all

 src # ls /usr/src/linux
Module.symvers  block    fs       ipc     mm       security  vmlinux
System.map      crypto   include  kernel  net      sound
arch            drivers  init     lib     scripts  usr

So again if anyone can help it would be great.

lokoalex,
Your kernel (2.6.22-gentoo-r8 ) apparently is not complete or otherwise damaged I think.
Try re-emergeing that kernel.
To make live easier you might want to install "mc".

Code: Select all

emerge -pv mc

and check if you agree with the dependencies it might want to install.
mc is a great console browser.It would have shown your dangling symlink in red.
Gerard.

[lokoalex]

How can I re-emerge 2.6.22-gentoo-r8 if they are up to 2.6.22-gentoo-r9?

[gerard27]

Code: Select all

emerge =gentoo-sources-2.6.22-r8

Read man emerge man ebuild etc.
Gerard.

[lokoalex]

You are awesome. Im still a little rusty with using the man pages thats why I asked for help. But im working my way there.

[gerard27]

No I'm 80.
Did this solve your problem?
Gerard.

[lokoalex]

You completely solved my problem. Thanks for all the help!!!

[haf1zoglu]

i had the same issue as ERROR: kernel source directory "/usr/src/linux" was not found!

yet what i have found was that i had just missed the step where we select the kernel and when i put command below and try "genkernell all" again, it worked like a charm.

eselect set kernel 1

(in my case it is 1, in your case it might be sth else, check via "eselect kernel list"

Code: Select all

root #eselect kernel list
Available kernel symlink targets:
  [1]   linux-5.15.52-gentoo
