I emerged gcc this morning to update from 3.2.3 to 3.3.2-r5, and after it finished emerge would get a python error like this:

Code:

/usr/bin/python: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory


etc-update would get this error:

Code:

/usr/bin/python: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory


I tracked it back to /etc/env.d/05gcc, which had both the 3.2.3 and 3.3.2 paths in the LDPATH variable. It sees that not finding the 3.2.3 directory was causing library loading to quit. I removed the 3.2.3 directory from LDPATH and everything seems to work.

Is there a problem with the ebuild for gcc 3.3.2-r5? Shouldn't it be removing the 3.2.3 path from LDPATH?

Just had the exact same thing. Darn!
:evil:

Solved it by commenting the line /usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.3 in /etc/ld.so.conf and updating the cache with ldconfig.

Seems the ebuild is indeed missing some cleanup steps!

Thanks for the advice! emerge just died after emerging gcc 3.3.2-r5 with the same error. I only had to run ldconfig to fix it, and all is back to normal. For a second I thought python was dead and I wouldn't be able to do anything without resorting to the LiveCD and a rescue!

May be the ebuild could be updated to run ldconfig for others?

ldconfig would give me an error about the gcc 3.2.3 path. Try:

Code:

ldconfig -v | grep gcc


and see if you see it reporting an error for the gcc 3.2.3 path. I traced that to /etc/env.d/05gcc and the extra path.

it happened to me today.

i went to /usr/lib/gcc-lib/i686.../ and symlinked 3.3.2 to 3.2.3 it fixed the problem. i reemerged python with hope that it chenged the library locations (with a lot of disbelieve) and it did not work.

later i saw this topic, changed the /etc/env.d/05gcc and 'ldconfig'd.

it works ok now. maybe the gcc ebuild has somethiing bad in it... is there a bug report associated with this?

Yup, 'ldconfig' worked for me too. Thanks all. Keeps my faith in Gentoo alive and well.

Yeah I was worried too when the same thing happened. I fixed mine by copying the missing libraries into /usr/lib, but yours seems to be a more elegant solution so I'll do that instead.

I love Gentoo, and I appreciate the efforts of all the developers, but I can't help feeling a but put off by the fact that occasionally, I end up with a showstopping problem. If Windows Update did the same thing I'm sure people would bitch and moan endlessly. (Ok, crap comparison)

More stringent ebuild testing needed. Hey, at least this way I get to seriously improve my Linux knowledge. There's a plus side to everything.

Worked for me too ;)

thought it was caused by my CTRL-C on an `emerge -u system` - thank god it wasn't.

I don't know if that's generally a bad thing to do, but what the hell... I took the chance.

Just another "me too" post so the people that didn't have a problem are more accurately represented.

ldconfig worked fine for me.

Editing /etc/env.d/05gcc did not work and running 'ldconfig' has not worked. I can't compile anything on my system and things aren't running so well. I don't know what to do from here. Help anyone?

Debian is there for a reason.

On Gentoo, it's a fact of life that you do a "emerge -up world" before a "emerge -u world", and when anything that looks dangerous (python (used by portage), gcc, glibc, and so on) is going to get updated, you check the forums before you do it.

Gentoo rocks because it can update non-trivial parts of the system with a large amount of automation, but it does place more of a burden on the user. emerge will almost always print a warning in yellow that tells you about anything you need to do in addition to the emerge, but there are times you need to do a little extra.

I removed distcc from the FEATURES list in make.conf and voila! I am a compilin. Does any know why distcc in combination with upgrading gcc would cause such a problem? I will explore this more myselft and post any answers.

Make sure that all hosts have the same gcc version (run `gcc --version` to find out)

If you haven't upgraded all hosts to 3.3.2, you will have a lot of errors!

Oh thank god! My system is saved. I thought it was cooked (right after I merged kde3.2!)

I couldn't start kde, so I started ob3, then firebird & konq wouldn't start (I was starting to think I wouldn't be able to make it to the forum). Then finally I found 2 apps that would work: xterm, and elinks. From there I found this thread, which saved my system!
