Looks like you're using clang, which is not supported, please try gcc.

When using gcc, I get:

g++ -fopenmp -msse -mfpmath=sse -O3 -DNDEBUG -c -o o/alignresult.o alignresult.cpp clang: error: unsupported option '-fopenmp' make: *** [o/alignresult.o] Error 1

I am on OSX, using the OSX make file.

Ah, ok. I haven't tested on OSX. The Makefile_osx is generated by an automatic conversion of the Visual Studio project file; it's worked for me with other projects but apparently not this one. So I guess I should not have implied that OSX is supported and I should delete the OSX makefile unless you can contribute a fix. My apologies for the mistake.

Installing llvm via Homebrew, installing macOS SDK headers to /usr/include, and directing CPP in the make file to /usr/local/opt/llvm/bin/clang fixes the issue. See: https://stackoverflow.com/questions/43555410/enable-openmp-support-in-clang-in-mac-os-x-sierra-mojave

However, a new issue occurs on compile:

myutils.cpp:928:2: error: 'va_start' cannot be used in a captured statement
        va_start(ArgList, Format);

Still clang-specific problems 😁, note the stdarg.h path. I think this should work if you use regular gcc, but regardless this is still a Mac-specific problem and regrettably I don't have time to commit to supporting urmap on Mac, not enough time vs. not enough users.
