[Bug 1272713] Re: Hello World does not compile with C++11

[Andreas Moog]

Thanks for the report. That is expected behaviour, gcc doesn't automatically include link libraries other than for C. You can use either
g++ -std=c++11
or explicitly add the standard c++ library to the command line:
gcc -std=c++11 test.cpp -lstdc++
