Somehow I cannot compile anything anymore.

root@isuck:~# gcc-config -c
* gcc-config: Active gcc profile is invalid!
[1] i686-pc-linux-gnu-4.3.2

...and just in case it's helpful, here's the story of what led up to this:

Yesterday I decided to update my system, and so I did, which caused an upgrade of X11. This apparently broke my mythtv, as it would segfault when run. In an effort to figure out what was wrong, I first re-emerged it, then I unmerged some stuff I thought might be messing it up (I don't remember what at all, I've been trying to get this to work all day), then made portage re-emerge that stuff. Then I remembered about revdep-rebuild, so I ran that, then tried some "emerge --update --newuse --deep world" and some "emerge --depclean", then tried revdep-rebuild again, etc. Somehow I came around to trying to re-emerge mythtv again, at which point it's configure script complained that it couldn't find something called FAAD, so I unmerged faad2, then tried to emerge faad2, but it failed in the configure, since the C compiler cannot create executables, it says.

The C compiler definately is there (i686-pc-linux-gnu-4.3.2), and it does create executables, it's simply that "i686-pc-linux-gnu-gcc" fails to find it.

I ran strace on "i686-pc-linux-gnu-gcc" and saw this interesting line:

execve(" \33[31;01m*\33[0m gcc-config: Active gcc profile is invalid!/i686-pc-linux-gnu-gcc", [" \33[31;01m*\33[0m gcc-config: Activ"...], [/* 48 vars */]) = -1 ENOENT (No such file or directory)

So I looked around and found it was getting that from this:

root@isuck:~# gcc-config -c
* gcc-config: Active gcc profile is invalid!
[1] i686-pc-linux-gnu-4.3.2

Now, normally, when something is broken, my first instinct is to unmerge it, then re-emerge it, in hope that that will fix it. However, I fear that if I unmerge this, I won't be able to re-emerge it. In fact, at this point, I'm afraid to shut down my computer since I worry it may not come back up again.

Searching the web, all I find is some comments that you shouldn't mess with your CHOST variable. I swear I didn't.

Anyway, I hope someone knows what is wrong, because I don't have a clue.

OK, after wondering if gcc-config does anything besides spit out the names of compilers, I figured out I could do this:

root@isuck:~# gcc-config i686-pc-linux-gnu-4.3.2
* Switching native-compiler to i686-pc-linux-gnu-4.3.2 ...

* Your gcc has a bug with GCC_SPECS.
* Please re-emerge gcc.
* https://bugs.gentoo.org/68395

>>> Regenerating /etc/ld.so.cache... [ ok ]

* If you intend to use the gcc from the new profile in an already
* running shell, please remember to do:

* # source /etc/profile

So now I am emerging gcc again, as it asked me to. It appears to be going well. I shall report again when I have more info.

Think I had it because I did emerge -P before gcc-config.
Despite the above error it seems to work after gcc-config x86_64-pc-linux-gnu-4.5.3.

same issue here after update :-) after running revdep-rebuild, which failed.. at some point emerge just reported no gcc found :-))) recreating the gcc config helped.

Im so glad I installed gentoo ... not .. what a crappy distro... last time Im using it in the cloud... emerge this ... ebuild that .. portage my ass... ubuntu seems a more likelier choice not..

freeswitch ... to name one... using it on 64 bit architecture is a nightmare .. even installing nginx and chrooting a nightmare... rpm based distros ftw...

don't get me start on sync and updates ... what crap... one thing cool is that text based has a nice colour system ...

warning stay away from unbuntoo , ubuntu means sharing in xhosa ...

This is the tradeoff for using a source based distro. I'm sorry you feel this way. As a side note the UBUNTU/DEBIAN/MINT/SUSE/FEDORA/<insert distro here> get the package thats gracefully installed in your system from the same source gentoo does. The only difference is that the fetching and compiling is scheduled as the STR and the LTR release schedules

SWEET! I was actually trying to do the Mate overlay process from Gnome 2, from here:

[url]
https://forums.gentoo.org/viewtopic-t-977288-highlight-mate+overlay.html
[/url]

and ran into a problem with the Introspection and vala flags hating each other when I actually got to the emerge -av mate step

Once I finally though I had things sorted, Python required a reinstall.

It died saying there was no active C compiler.

Code:
gcc-config -c


"But it's right there...!" :evil:

I tried to reinstall the toolchain... same problem.

Until I found this thread that actually let me reselect the GCC profile, I was stumped.

reinstalling toolchain and python now, I'm betting this is going to solve the problem with introspection.

Does this translate into english somehow? Or do you just have a stutter even while typing?



Anyway similar prob to OP, was cleaning out old packages and came across the gcc error, stopped doing that to fix it as i know removing an old gcc when the new one isn't working leads to a massive problem.

Code:
lilith ~ # gcc-config -c
 * gcc-config: Active gcc profile is invalid!

 [1] x86_64-pc-linux-gnu-4.7.3
lilith ~ # gcc-config x86_64-pc-linux-gnu-4.7.3
 * Switching native-compiler to x86_64-pc-linux-gnu-4.7.3 ...
>>> Regenerating /etc/ld.so.cache...                                      [ ok ]

 * If you intend to use the gcc from the new profile in an already
 * running shell, please remember to do:

 *   . /etc/profile

lilith ~ # . /etc/profile
lilith ~ # gcc-config -c
x86_64-pc-linux-gnu-4.7.3
lilith ~ # gcc-config -l
 [1] x86_64-pc-linux-gnu-4.7.3 *


Was my output, all fixed now as you can see.
