World update broke my system

[renketsu]

Ok, so it's not really broken but it's not doing anything I want it to do. This isn't the first time a world update has broken my system so this time rather than reinstalling I want to try and fix it (if it's worth the time) and prevent it in the future.

This time I didn't know what I was doing setting ACCEPT_KEYWORDS="~amd64" in my make.conf rather than just using it for a single command. I knew it was a bad thing to have set globally, but after I emerged compiz I forgot to comment it out. Then I performed the world update and everything broke. kdm no longer works, any attempts to downgrade all my packages end up failing to a compiler error, and all my attempts to downgrade my compiler fail as well to the same error.

The specific error I'm getting is with configuring. Regardless of what package I'm trying to install it will say "failed to run configure" at the end of it.

Here is a call stack from gcc
Call stack:
ebuild.sh, line 56: Called src_compile
environment, line 4874: Called toolchain_src_compile
environment, line 5471: Called gcc_src_compile
environment, 3080: Called gcc_do_configure
environment, line 2812: Called die
The specific snippet of code:
"${S}"/configure "$@" || die "failed to run configure";

I would post more info but I don't have a clue how to copy from the command line interface, let alone how to use the forums in CLI.

Never do per-package changes via temporary modifications to /etc/make.conf. If you want to make a change for only one package, then do a per-package override via /etc/portage/package.use or /etc/portage/package.keywords, as appropriate.

If configure fails, then we need the error message from configure to be able to help you.

I know this isn't the version of gcc I want but it's pretty much the same error for all packages I try emerging, no matter what the version
emerge -av gcc
...
...
...
checking whether ln -s works... yes
checking for x86_64-pc-linux-gnu-gcc... x86_64-pc-linux-gcc
checking for C compiler default output file name... configure: error: in '/var/tmp/portage/sys-devel/gcc-4.4.5/work/build':
configure: error: C compiler cannot create executables
See 'config.log' for more details
(I don't know where this log is)

(call stack here)

I have a feeling fixing this is going to take more time and effort than just reinstalling, which leads me to my next request. Is there any way I can make emerge -uNDav world any safer? I really want to be able to update all the packages on my system but every time I have used this my system has broken. That's including in the past, when I wasn't using unstable keywords and everything else on the system seemed perfectly normal. Should I mask certain packages before the update? any options I can add? Or should I just avoid using -D altogether?

run binutils-config 1.
for some reason you lost you assembler's capability to build elfs.

Do you know which version of gcc I should downgrade to? gentoo-portage.com is down so I can't see what the latest stable build is there.

[renketsu]

Oh wow, wrong site. Turns out gcc 4.4.5 is is stable for amd64 here.

[renketsu]

Ok, I've come across another error. A lot of my packages are not recognizing my compiler as 4.4.5, giving me error messages like "Sorry, but gcc earlier than 4.0 won't work for xorg-server" and "Sorry, but gcc-4.3 and earlier won;t work for KDE SC 4.6" I'm not very patient when it comes to this type of stuff so I'm just going to reinstall. I can keep a lot of my old configuration and I should be able to reuse my kernel. Should just be a matter of formatting, installing the base, copying my config files, and emerging world. Next time I will backup before I try a world update and if something goes wrong I'll post it and see if it can be fixed. If not I'll just avoid the -D option.

Would you mind finally putting that config.log into pastebin ?

[renketsu]

1. I don't know where that file is
2. I don't know how to use pastebin from CLI
3. I don't know how to copy-paste from CLI

If you could tell me how to do those within the next hour I will. If not I reformat and reinstall. I don't mean this as an ultimatum or anything, but I have a lot of things to do soon and you could say my "week off" is almost over. If I don't get a working gentoo system before my free time runs away I would have to resort to using another distro.

[VoidMage]

"I don't mean this as an ultimatum"... yeah, right.
That config.log should be in the build dir and there's always wgetpaste, if you can't find the error in it by yourself.

Ok, after looking at the definition, I guess it technically does qualify as an ultimatum. What I meant is that it isn't aimed at you. My schedule is what created it, and I to blame for my schedule but I didn't expect my system to break right after being nearly done installing it. Adding another install to my plans took me from comfortable to rush mode if I plan to be done before I have to get back to work. Thanks for the help.

Your installed =sys-devel/gcc-4.4.5 is linked to a library that has gone missing. Have you been removing packages via --unmerge or downgrading installed packages? Have you had any filesystem corruption problems?

[renketsu]

I tried downgrading the system back to it's previous state by removing the ~amd64 from my make.conf and emerging world again. No filesystem corruption problems.
