Apologies if this is not the best place to post this question, redirection appreciated. My program requires OpenMP and uses some somewhat modern C++ features. Consequently, on OSX, I can't use Apple's GCC (too old for C++11 stuff), and I can't use Apple's XCode (or anyone's) CLang/LLVM based compilers (no OpenMP). I am currently using GCC 4.8 as installed via MacPorts. The exact version isn't that important to me, I can upgrade/downgrade slightly if required. I also use CMake heavily, so CMake aware solutions are appreciated, but not required. I keep an old OSX 10.7.5 machine around to build my distributable files on, the resulting binaries generally work on a broad range of versions of OSX. This works for me, but I would like to distribute precompiled binaries to my users. My program is open source, but not GPL. When I specify -fopenmp, the program is dynamically linked to libgomp.1.dylib. I read that -static is not supported on OSX, as the Apple system libraries are not provided with static variants. So, is there a way to statically link libgomp in this situation? Or, will I need to distribute libgomp.1.dylib with my program? Does the license allow this? Being a good citizen, where should I put the file? I would prefer my users not to have to use sudo to install if they don't absolutely have to. My program is currently not a Package, it is just an executable and some data files distributed in a *.zip. I would rather not force my users to install MacPorts, would using the hpc.sourceforge.net built GCC provide an easier path? Thanks for any advice, Rob
