The code in this directory is written about at: http://wp.me/p1Pqiu-9X The basic idea is that CUDA under OS X is only supported with g++, and in fact clang++ will choke due to a number of reasons, one of which is support for certain atomic instructions, the names of which escape me now. On the other hand the g++ that ships with OS X does not support C++ 11. So what is one to do if one wants to use C++ 11, OS X, and CUDA simultaneously? This is one possible solution. That said, the robustness of it is IMO highly suspect. Hopefully NVIDIA will suport clang++ or Apple will support a version of g++ with C++ 11 support soon. Until then at least I can move forward. Files: README - This file. Makefile - Build instructions for nvcc, g++, and clang++ on OS X Mountain Lion square.cu - A CUDA code for squaring an array of floats. This is compiled with g++. main.cxx - A main line which allocates host and device memory and runs the CUDA code. This file is compiled with clang++. All linking is done with the clang++ tool chain. Notes: * Use of std::cout under g++ causes link errors. This is due to some vagaries with static initializaton, probably related to how iostream is implemented. This only seems to happen when c++-11 support is on in clang, however.
