Title:
After upgrading to 13.10, clang and GCC erroneously look for GCC-4.7
headers
Status in “gcc-4.8” package in Ubuntu:
Fix Released
Bug description:
I'm a Firefox developer. 13.04 was working fine. I upgraded to 13.10
and now I can't compile Firefox with either clang or GCC.
Here's a reduced test case:
#include <memory>
int main(void) {}
If I compile this with clang I get this:
[fjord:~/moz/mi5] clang++ a.cpp
In file included from a.cpp:1:

The results with GCC are similar.
I found the problem is that both clang and GCC are somehow configured
to look for some GCC 4.7 headers as well as GCC 4.8 headers -- both of
them have |-I/usr/lib/gcc/x86_64-linux-
gnu/4.7/../../../../include/x86_64-linux-gnu/c++/4.7| hardwired in the
default flags.
As a workaround, I renamed /usr/include/c++/4.7/ and
/usr/include/x86_64-linux-gnu/c++/4.7/ so the compilers could no
longer find them, and now things are working normally. But obviously
this should be fixed properly.
