description |
The clang++ driver will not find standard C++ headers and the libstdc++ library when there is gccgo-4.9 package installed as well. This appears to be due to gccgo-4.9 installing few things into /usr/bin/lib/gcc/x86_64-linux-gnu/4.9. The clang++ driver sees this directory and thinks it contains full C++ headers and run time installation when it does not, because there are only some parts relevant to gccgo-4.9. Uninstalling gccgo-4.9 fixes the issue because clang++ then finds only the 4.8 directory and uses that.

Uninstalling gccgo-4.9 fixes the issue because clang++ then finds only the 4.8 directory and uses that.
The same issue occurs with gccgo-5 and GCC 5, which installs a partial GCC 5 installation, enough for the clang++ driver to try to use it but not including libstdc++ so clang++ fails to build.
