build on Mac

[youngung]

Thanks for the great work. I'd like to test run some cases using neper so I just started trying to build it on my Mac. And I encountered below error messages over the course of "cmake -DHAVE_OPENMP=OFF .. && make"

Could you please guide me to help resolve this issue?

There is at least one issue, which is that CMake uses both Neper's built-in muparser (src/contrib/muparser) and a system muparser (/usr/local/include/muParser*). Did you install muparser on your system?

[youngung]

Yes, I did install muparser separately. Do you recommend removing it?

[youngung]

Thanks! Removing muparser (installed earlier using homebrew) resolved the issue. I had to have scotch installed on my system (using again homebrew). Do I have any chance to build neper with openMP on MacOS?

[rquey]

Great.

I don't know for sure about building with openMP on MacOS. @mkasemer can probably tell you this...

[mkasemer]

The default compilers on Mac have many issues, not least of which is there is no native support for OpenMP (frustrating, as this has been a known issue for awhile). The easiest solution (that I have found, after iterating a few times) is to install llvm compilers via homebrew, and make sure that (using default symlink locations):

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

[youngung]

Thanks! I was able to build with openMP on my Mac.
