Turns out, that something like "gcc-config i686-pc-linux-gnu-3.4.3" hasn't been run. HOWEVER, I still consider this as a bug. I got 3.4.3 installed, because of a "emerge -Du world". After 3.4.3 got installed, emerge carried on to install other packages. IMO, it should've stopped and it should've informed the user.
> i686-pc-linux-gnu-gcc: /usr/lib/gcc-lib/i686-pc-linux-gnu/3.4.2/specs: No such file or directory I got the same, even after source /etc/profile. Apparently GCC_SPECS that was set in my env (to .../3.4.2/specs) is not exported by gcc-config (/etc/env.d/gcc/?) any more, but used by gcc. After unset GCC_SPECS it worked again...
the line GCC_SPECS="/usr/lib/gcc/i686-pc-linux-gnu/3.4.3/specs" is missing from /etc/env.d/gcc/i686-pc-linux-gnu-3.4.3 It also appears that ebuild never ran gcc-config.
thanks Harris Landgarten, adding GCC_SPECS="/usr/lib/gcc/i686-pc-linux-gnu/3.4.3/specs" to /etc/env.d/gcc/i686-pc-linux-gnu-3.4.3 and editing /etc/env.d/gcc/config to 3.4.3 fix everything, i'm able to compile again. it seems there is something broken in the ebuild.
Me too (adding CC). Workaround suggested works. Phil
There seems to be a further problem with g++. Ebuilds are still looking for 3.4.2 libraries and failing.
LDPATH in /etc/env.d/05gcc is not being updated correctly. Mine still contained /usr/lib/gcc/x86_64-pc-linux-gnu/3.4.2 and no 3.4.3 entry.
