I run a few tests regarding clang and omp after installing OSX 10.11 and Xcode 7.3.1.
It seems that clang-omp-3.5 from libs can’t compile using OSX 10.11 SDK. So, I downloaded clang 3.7.0 and 3.8.0 darwin binaries from official page and both compile blender ok after a minor modification on cmake. diff --git a/build_files/cmake/platform/platform_apple.cmake b/build_files/cmake/platform/platform_apple.cmake index b28b748..ec40400 100644 --- a/build_files/cmake/platform/platform_apple.cmake +++ b/build_files/cmake/platform/platform_apple.cmake @@ -376,8 +376,13 @@ if(WITH_OPENMP) message(STATUS "Using special OpenMP enabled compiler !") # letting find_package(OpenMP) module work for gcc if(CMAKE_C_COMPILER_ID MATCHES "Clang") # clang-omp in darwin libs set(OPENMP_FOUND ON) - set(OpenMP_C_FLAGS "-fopenmp" CACHE STRING "C compiler flags for OpenMP parallization" FORCE) - set(OpenMP_CXX_FLAGS "-fopenmp" CACHE STRING "C++ compiler flags for OpenMP parallization" FORCE) + if(CMAKE_CXX_COMPILER_VERSION VERSION_LESS 3.7) + set(OpenMP_C_FLAGS "-fopenmp" CACHE STRING "C compiler flags for OpenMP parallization" FORCE) + set(OpenMP_CXX_FLAGS "-fopenmp" CACHE STRING "C++ compiler flags for OpenMP parallization" FORCE) + else() + set(OpenMP_C_FLAGS "-fopenmp=libiomp5" CACHE STRING "C compiler flags for OpenMP parallization" FORCE) + set(OpenMP_CXX_FLAGS "-fopenmp=libiomp5" CACHE STRING "C++ compiler flags for OpenMP parallization" FORCE) + endif() include_directories(${LIBDIR}/openmp/include) link_directories(${LIBDIR}/openmp/lib) # This is a workaround for our helperbinaries ( datatoc, masgfmt, ... ), After the tests I have not found any issues with cuda 7.5 and xcode 7.3.1 or clang 3.7/3.8 but I guess it’s because I am using the latest version and is seems to have fixed incompatible compiler issues but as I don’t know what the cuda-hack does, I am not sure. Any comment on what the cuda-hack does/solves is very welcome.
