gcc-config: Active gcc profile is invalid!

[peajay]

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.

Hooray! Things compile again!

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.

Thanks peajay. I had the same problem after updating tonight. This seems to have fixed it for me too.

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.

[robgraves]

Awesome! This helped me as well. I just had gcc update and nothing compiled afterwords, this fixed it.

Thanks.

[doalwa]

Thanks, helped me too...I committed the sin of not updating my Gentoo VM for close to a year and just knew I was in for a ride when I finally updated world yesterday

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 ...

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

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.

Thank you for the info. The gcc-config command fixed a similar problem I was having today.
