Description Amadeusz Sławiński 2012-01-20 00:45:05 UTC
From what I understand changing gcc with gcc-config fails to change file containing information which compiler to use and with which specifications. So for all purposes it basically fails.

Reproducible: Always

Steps to Reproduce:
root@voidwalker $ gcc-config 2  
 * Switching native-compiler to x86_64-pc-linux-gnu-4.5.3-hardenednopie ...
/usr/bin/gcc-config: line 268: cannot create temp file for here-document: Permission denied
tac: failed to create temporary file in `/tmp': Permission denied
rm: cannot remove `/etc/env.d/gcc/.NATIVE': Permission denied
ln: cannot remove `/etc/env.d/gcc/.NATIVE': Permission denied
>>> Regenerating /etc/ld.so.cache...
/sbin/ldconfig: /opt/intel/Compiler/11.1/072/idb/lib/intel64/libxerces-c.so.27 is not a symbolic link
                                                                          [ ok ]
Actual Results:  
Compiler and/or specifications are unchanged

Also some binaries doesn't work after this, example error:
mplayer2: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

Expected Results:  
It works.
