Stupid me deleted gcc libs... new install? [solved]

[hcintra]

After a long hours trying to finalize gcc upgrade, I decided to delete some remaining libs from the unmerged gcc 3.4.6, but very stupidly instead of deleting the 3.4.6 lib folder, I copied the addres of the top folder and got 4.1.1 libs deleted together...

Now I can't emerge anything, not even ggc back.

Is there a route that would not involve returning to LiveCD?

If I have to resort to LiveCD, what minimal actions should I perform?

I was very happy with my system at this point, because of the gcc upgrade I had done a very good tunning it up.

You can recover this way:

1. On a filesystem with at least 500 MB free space (e.g. /home/hcintra), do

   Code:

   mkdir /home/hcintra/stage3 && cd /home/hcintra/stage3

   
   
2. get a stage3 tarball for your arch and unpack it:

   Code:

   tar -xjf /path/to/stage3.tar.bz2

   
   
3. make a portage dir:

   Code:

   mkdir usr/portage

   
   
4. mount your local portage tree (you have to be root from now on):

   Code:

   mount --bind /usr/portage usr/portage

   
   
5. chroot to your stage3:

   Code:

   chroot /home/cintra/stage3 /bin/bash

   
   
6. build a binary package of sys-devel/gcc:

   Code:

   quickpkg sys-devel/gcc

   
   
7. exit chroot:

   Code:

   exit

   
   
8. emerge the binary gcc:

   Code:

   emerge -K sys-devel/gcc

   
   
9. make sure the binary installed gcc is selected:

   Code:

   gcc-config -l

   if it is not, select it with

   Code:

   gcc-config <number of correct gcc profile>

   
   
10. reemerge gcc:

    Code:

    emerge sys-devel/gcc

    
    

HTH.

Fantastic. Thank you very much.

I am jumping to it right now.
