Running nvcc on C++ code gives errors akin to

/usr/lib/gcc/x86_64-unknown-linux-gnu/4.7.1/../../../../include/c++/4.7.1/ext/atomicity.h(48): error: identifier "__atomic_fetch_add" is undefined

The problem seems to be with GCC 4.7. If one installs GCC 4.6, and symlinks its gcc and g++ into /opt/cuda-toolkit/bin, C++ code compiles fine.
This task depends upon

This is an upstream problem. The solution is easy to find using Google. You need to add 2 precompiler directives.
