[gentoo-user] GCC gone bad! Help!

[gentoo-user] GCC gone bad! Help!

[Michael Sullivan]

I've started seeing this line after failed emerges: 



checking for C compiler default output file name... configure: error: C
compiler cannot create executables

Checking gcc-config returns this:
carter sys-devel # gcc-config -l
 * gcc-config: Active gcc profile is invalid!
 [1] i686-pc-linux-gnu-4.3.4


How can I get gcc back?  Here's some other information on the system:
carter ~ # emerge --info
!!! No gcc found. You probably need to 'source /etc/profile'
!!! to update the environment of this terminal and possibly
!!! other terminals also.

Maybe it helps you.

Please send the contents of the config log for the package you are trying to
build - it should approximately be in
/var/tmp/portage/$CATEGORY/$PACKAGE-$VERSION/work/$PACKAGE/config.log

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was

There's your problem right there, Vern... ;)

Run gcc-config -l
Pick the gompuler that looks best (most likely #1), then run
gcc-config <compiler_number>
source /etc/profile

Then try running
gcc -v

If you get output that looks sane (ie. no "command not found" message), then
you should be good to go - try emerging again.

HTH-

gcc-config manipulates the contents of /etc/env.d/gcc

$ls -la /etc/env.d/gcc
total 24

try to run "gcc-config 1" as root to have it re-configure your gcc
settings/links.
