Bug 4812

Same thing happened when I tried to do a simple compiler test on MPC8315e

But using gcc (version 4.7.2) doesn't has this problem.
It looks like that gcc didn't look for header files from /usr/include/c++, which means "--with-gxx-include-dir=/usr/include/c++/" doesn't work.

This should be the same problem that Stoicescu Cornel encountered.

Plus, if I specify header dir with -I /usr/include/c++,  compiling is OK.

This looks like a configuration issue with the target gcc missing some setup.

*** Bug 4829 has been marked as a duplicate of this bug. ***

sometimes applications use precompiled headers and can end up in such issues.
Can you try to compile a simple c++ program like helloworld and see it it can
find the headers ?

something like

#include <iostream>
#include <cstdlib>

int main()
{
    std::cout << "Hello, World!" << std::endl;
}

if that compiles then we do not have issue with gcc.

It indeed fails with the same error.
