[gentoo-user] Two gcc versions installed

[Daniel D Jones]

eix gcc shows:

 Installed versions:  

4.3.4(4.3)!s(10:56:18 AM 02/27/2010)(gtk mudflap nls nptl openmp -altivec -
bootstrap -build -doc -fixed-point -fortran -gcj -hardened -libffi -multilib -
multislot -n32 -n64 -nocxx -nopie -objc -objc++ -objc-gc -test -vanilla) 

4.4.3-r2(4.4)!s(08:29:19 PM 06/07/2010)(fortran gtk mudflap nls nptl openmp -
altivec -bootstrap -build -doc -fixed-point -gcj -graphite -hardened -libffi -
multilib -multislot -n32 -n64 -nocxx -objc -objc++ -objc-gc -test -vanilla)

Is there any reason to have both of these installed?  Is it safe to unmerge 
4.3.4?

I usually keep the last version of GCC around until I've managed to rebuild the entire world with 
the newer one, just in case. If you've run the tasks mentioned after the newer version was 
installed, it should probably be safe.

Probably not. I would do an emerge -a --depclean. If nothing depends on 
the old gcc, it will be removed. Otherwise you get a message what has to 
be rebuilt, like I do:

weird ~ # emerge -a --depclean

 * As a safety measure, depclean will not remove any packages
 * unless *all* required dependencies have been resolved.  As a
 * consequence, it is often necessary to run `emerge --update
 * --newuse --deep @world` prior to depclean.

Did you run "fix_libtool_files.sh 4.3.4" after switching gcc versions
with gcc-config before trying depclean?
