[gentoo-user] recoverning from deleted gcc

[gentoo-user] recoverning from deleted gcc

[James]

Hello,

Several poor decisions has led to a system with no gcc-3.3.6. only 3.4.

emerge -v =sys-devel/gcc-3.3.6

fails:

<snip>
*** This configuration is not supported in the following subdirectories:
     target-libffi target-boehm-gc target-zlib target-libjava zlib fastjar
target-libobjc
    (Any other directories should still work fine.)

gcc-config error: Could not run/locate "gcc"
*** The command 'gcc -o conftest    conftest.c' failed.
*** You must set the environment variable CC to a working compiler.

any suggestions as to how to recover, install gcc-3.3.6 again?

Run 'gcc-config -l' (letter L, not number 1), and then run gcc-config 
again with the number of the first 3.4 compiler in the list (e.g. 
'gcc-config 1').  Then try your emerge again.  If emerge is still 
working even with 3.3 gone, however, there's a decent chance you don't 
need 3.3...

I think you are right.  I have this on mine:

As you can see, I am using 3.4.6 and 3.3.5 is just still hanging
around.  I guess I need to get rid of that.  ;-)

gcc-config -l
gcc-config 3.4.6
env-update && source /etc/profile && etc-update && update-eix && eupdatedb

eix gcc
* sys-devel/gcc
Installed:           3.4.6-r1


Worked like a charm. gcc 3.3.6 is gone and gcc-3.4.6-r1 is
working like a charm.

Thanks for the tip!

James
