I found to resolve this issue that after installing libstdc++-4.8-dev package, I need to specify the include paths and lib path to the clang++ like this.
clang++ -I/usr/include/c++/4.8/ -I/usr/include/x86_64-linux-gnu/c++/4.8 -L /usr/lib/gcc/x86_64-linux-gnu/4.8 test.cpp -o test
Your code works for me. Make sure you have libstdc++-dev installed. It's a virtual package, and in my case (Ubuntu 14.04.2 LTS) having 4.8 works.
sudo apt-get install libstdc++-4.8-dev
