GCC problem : broken during emerge [SOLVED]

Hi,

I was on my way of upgrading my X server with emerge --deep xorg-server, when portage wanted to upgrade GCC 4.1.1-r1 to the latest version available (aka. GCC-4.1.2).
The merge of GCC seemed to raise no problem, but the next emerging package (glibc-2.6.1) has broke.
In fact, it seems that GCC can't be find again on my system.

If I type "gcc", it says that "gcc-config error: Could not run/locate "gcc"".
A gcc-config -l command issue the following :

Are your config files up-to-date? Try dispatch-conf to make sure.

There was about 170 files to be updated (mainly keyboards layout for various countries), but that didn't changed anything for gcc...

You did env-update && source /etc/profile ?

I run it before dispatch-conf.
I re-run it just now, and still, nothing changes

I checked meanwhile that 4.1.2 is installed, and yes, it's installed in /usr/i686-pc-linux-gnu/gcc-bin/4.1.2/.
I even got a symlink called "gcc" that points to i686-pc-linux-gnu-gcc in this directory.

I also got a a file called "i686-pc-linux-gnu-4.1.2" in /etc/env.d/gcc which contains the following :

And you still can't run gcc-config -l ?

yep, I still can't.

What happens if you run /usr/bin/gcc --version ?

If you can't run that, my best bet would be to boot off a live-cd, chroot into your system and remerge gcc

In fact, in this /usr/bin/ I got :

ok, let's rock !
I'll shutdown in a few moments, time to save some files and let you know the results

thanks anyway for your precious help so far

No, same results : I've booted with a liveCD (not the Gentoo LiveCD I've to admit) and the result is exactly the same : still can't find GCC on my computer.
I'm currently running this LiveCD, my gentoo can't boot in X session.
The rest of my computer is broken as I need probably to run fix-libtool_files.sh but I can't as he can't find gcc.

Is there any other way than a complete gentoo reinstall ??

If you boot on a Gentoo livecd you can emerge portage again. I assumed that was the livecd we talked about, sorry for not being explicit about it.
With the Gentoo livecd you will have a working gcc so you can emerge a new one on your system.

I managed to get gcc working again, even without using the Gentoo LiveCD.
In fact, there was a gcc file in my /usr/bin but this 8 kB file couldn't be the real compiler and wasn't a symlink.
I renamed it and made a link to the 4.1.2 compiler and it worked again !
I downgraded gcc to 4.1.1-r3 and the emerge goes fine even if gcc-config still complains about not finding CHOST variable ?
I'm just finishing my xorg-server update and I'll try to fix that CHOST issue with a real Gentoo-Live CD, but I already re-emerged portage with no luck on side of the gcc-config.

I've also removed the gcc link that I've manually made for gcc-4.1.2 compiler to found since I remerged 4.1.1-r3 and everything seems to run smooth.

Stay tuned for more to come soon, but still many many thanks for the help you gave to me !!!

Your welcome

I'll stay tuned.

ok, back on rails with KDE 3.5 and Gentoo up and running.

Still, huge thanks for your precious help, but still I think my gentoo is kind of unstable as gcc-config still refuses to work.
I don't care, I change my computer in a month. I'll recompile everything from scratch with my new gentoo.

I also had problem with "libexpat.so.0", but I made the link manually and it's ok now.

As always, I really like gentoo, but it's annoying to have so much problems each time you want to do an upgrade.
Perhaps the upgrades are less dangerous when waiting for official releases, but I'm always having lot of troubles when emerging world for an update.
Probably the price to pay for having a full customized linux ?

Sounds like revdep-rebuild could save you some trouble? Your choice - a new box is always a good candiate for gentoo

Have fun.

I don't trust revdep-rebuild at all !
revdep-rebuild is the devil sometimes :twisted:

Earlier today, after that I've to finish compiling all my upgrade, I said that I had a problem with a library that couldn't be found : libexpat.so.0.
It was a simple symbolic link to make in /usr/bin to fix the problem.
If I had followed the revdep-rebuild script, I'll still be compiling one of the 100+ ebuilds he wanted to rebuild, among some being hard-masked.

Anyway, run here, revdep-rebuild says my system is ok (glad to know that !)

I haven't got a lot of bad experience with revdep-rebuild. I'd say that if revdep-rebuild wanted to build 100+ packages you would have problems bigger than revdep-rebuild anyway

Glad your box is ok now. Take good care of it :p
