[Bf-committers] Error compiling blender on Mac

[Arto Kitula]

There has been problem with many brewed libraries clashing with lib/darwin libraries.

BTW if you want to build OMP enabled build of master on your macOS, you can use brew llvm clang with setting first env variables:

CC=/usr/local/opt/llvm/bin/clang
CXX=/usr/local/opt/llvm/bin/clang++
LDFLAGS=-L/usr/local/opt/llvm/lib
CPPFLAGS=-I/usr/local/opt/llvm/include

and then run cmake.

Keep in mind that binary is then using runtime libs libc++.1.dylib and libomp.dylib from /usr/local/opt/llvm/lib/ so the binary won’t run on systems that don’t have them. You can bundle them yourself to blender.app/Contents/Resources and set blender.app/Contents/MacOS/blender to load them from @loader_path relative. We’ll do automated build for that later on, probably when updating LLVM from the lib/darwin.
