[SOLVED] Emerging sys-devel/gcc-4.6.3 fails during configure

I'm currently trying to emerge steam-client-meta from the steam-overlay, which requires me to emerge gcc-4.6.3.

This however fails during configure for a reason I don't understand.
Here's my config.log, which shows the error message

is it possible that you have a make.conf file in /etc/portage/ that is suppressing the one in /etc/ ?

Good thought, but the make.conf in /etc is the only one I have

Hydrael,

Please select x86_64-pc-linux-gnu-4.5.4 and try again.

If that fails, set -march=native, in place of your -march=opteron

Unfortunately that didn't work either.

But what I found out now:

Here you go

Hydrael,

You are still using gcc-4.4.7 and CFLAGS="-march=opteron -O2 -pipe"
gcc-4.5.4 is stable gcc now, so you should use it.

Everything looks OK. You don't say what didn't work. The newer gcc or -march=native ... or both.

Sorry, my bad.
I had switched to gcc-4.5.4 and attempted emerging gcc-4.6.3, set -march to native and attempted emerging gcc-4.6.3 and then did both things at once and attempted emering gcc.
Since none of these attempts worked, I switched back to 4.4.7 and -march=opteron, because other than with emerging gcc-4.6.3 I hadn't had any problems with that configuration.

But since 4.5.4 is stable, I guess I'll switch over to 4.5.4 for real now

Hydrael,

I've changed my CFLAGS to use -march=opteron and reverted to gcc-4.5.4 but am unable to reproduce the issue.

Going back to gcc-4.4.7 is harder, as its no longer in the portage tree.

For a WAG, try testing versions of

Thanks a lot - your last hint did the trick!

/etc/portage/env/sys-devel/gcc contained the -march=generic that was causing the problem.
I never put anything in that file knowingly, but changing the line to -march=opteron worked.

gcc-4.6.3 is compiling right now.

Thanks a lot again...I really appreciate the help

Hydrael,

That file does not exist until you create it.
Its intended for olds and ends like that thay you want different on a per package basis, you should delete it if its the same as the rest of your system.

I suppose I must have created it a while ago and then forgot about it
