# gcc-config 1
* Switching native-compiler to x86_64-pc-linux-gnu-4.9.3 ...
tac: failed to create temporary file in ‘/tmp/.private/root’: No such file or directory                                                                [ ok ]
but /etc/ld.so.conf.d/05gcc-x86_64-pc-linux-gnu.conf is empty I see things like

 # msgmerge -U ./tmp-po/da.po ./tmp-po/man-db-manpages.pot  --previous --backup=none
 msgmerge: error while loading shared libraries: libgomp.so.1: cannot open shared object file: No such file or directory
 
 
After creating the temp die manually and running gcc-config again everything is fine.

This won't have anything to do with gcc-config.  It's just a simple `tac` call that's failing because it can't write a temp file.  This should be controlled by the pam mktemp module.  If you're in a chroot try doing a su - first even if you're already $UID 0.
