[resolved]Problem compiling apps after gcc upgrade

Question

Hi all,
I've recently upgraded gcc to the last version, but since I've got errors as soon as I try to compile apps with optimisation enabled.
Here is an exemple:
File main.cpp:
#include <iostream>
using namespace std;
int main(int argc, char** argv)
cout << "Hello World" << endl;
return 0;
then
bash# g++ -O main.cpp
/tmp/ccZDcDGc.o: In function `main':
main.cpp:(.text+0x93): undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std::__ostream_insert<char, std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*, int)'
collect2: ld a retourné 1 code d'état d'exécution
Do I need to upgrade another package? (I've upgraded gcc, gcc-libs and libstdc++5)

this should give you enough clue
