[SOLVED] i broke emerge

[nickel]

7hi everyone!

I did something pretty idiotic. I unemerged python-exec!!!!
I can't emerged anything and it also broke the system. Well, no wonder there.

I tried to fix it following this wiki.
It didn't work. Don't know why. I changed like suggesteddd DISTDIR, PORTDIR, etc, to point to my mounted gentoo, but the livecd still used its own portage.
I tried this post.
i can emerge apparently, but i got this:

Code: Select all

when i try gcc-config -l

 * gcc-config: Could not get portage CHOST!
 * gcc-config: You should verify that CHOST is set in one of these places:
 * gcc-config:  - //etc/portage/make.conf
 * gcc-config:  - active environment

so, i thought, i forgot to run source /etc/profile && env-update and i got this

Code: Select all

/usr/sbin/env-update: no supported Python implementation variant found!

can i fix it? or it is beyond salvation and have to reinstall the whole system?

I'm not sure I can follow. The livecd is _supposed_ to use its own portage. You use the livecd portage version to install a new portage into the chroot environment.

Please be more specific about what you did and what didn't work.

I unemerged python-exec!!!!

Phew, not so bad after all. Recording here for posterity, and for the next time I do this.

edit make.conf, add the line: PORTAGE_BINHOST="http://tinderbox.dev.gentoo.org/default-linux/amd64/"
sync the new repo: emerge --sync
install binary version: emerge -av --binpkgonly --usepkgonly dev-libs/mpc
compile source version: emerge -av dev-libs/mpc

should be similar afaik. ... you need to search for the binary host ...

and just pull back that pyton-exec. and you may also find a clue what it does when you look at the ebuild and try to do it by hand ...

[Roman_Gruber]

I wrote you a personal message ...


So it should be only this when only python-exec is the issue.

nickel,

Its very difficult to break Gentoo so badly that a reinstall is the only way to fix it.
unemerging python-exec is not one of the ways.

This thread will help and you don't even need a BINHOST, as you might if you removed glibc or gcc.

you're right. Sorry about that!

If i understand correctly, the whole idea of that wiki, was to re-emerged portage in the broken system.
Using a livecd with portage, it should be achieved by changing some global variable to emerge in /dev/sda5 (my system, which is mounted in /mnt/gentoo).
But it doesn't work. No idea why. The vars are correctly changed

That's not a useful error description. What does not work? Did you re-emerge python-exec in the same way?

i followed that post, but i got some problems:

[NeddySeagoon]

nickel,

/usr/lib/portage/python2.7/ebuild.sh: No such file or directory
Do you really not have that file?

Portage works with Python 3 too.

You can try

Code: Select all

/usr/lib64/python-exec/python<ver>/emerge -av1 dev-lang/python-exec 

Where <ver> is a version of Python that you do have.

If /usr/lib/portage/python2.7/ebuild.sh is missing, it looks like you did more than remove python-exec

don't kill me. I forgot to mention, i used this wiki as well, after the first one didn't work. But i didn't remove anything in /usr/lib/portage/ only in /usr/lib64/portage/. Perhaps can i do a symbolink link back to /usr/lib/portage?
No matter what version i use, i still got the same error.

That's not a useful error description. What does not work? Did you re-emerge python-exec in the same way?

the problem is, it still uses its own DISTDIR, PORTDIR, PKGDIR, ... and not the ones i "changed". So, t emerges in the livecd, not in /mnt/gentoo

that worked! thx!
turned out, i have to emerge python, gcc as well.
