Compile error - unsupported option '-fopenmp'

[george-githinji]

I ran into the following error on Macos

cd mkmh && /Applications/Xcode.app/Contents/Developer/usr/bin/make
g++ -O3 -std=c++11 -fopenmp -mtune=native -ggdb -c HASHTCounter.cpp -Lmurmur3 -L. -I. -Imurmur3
clang: error: unsupported option '-fopenmp'
make[1]: *** [HASHTCounter.o] Error 1
make: *** [mkmh/libmkmh.a] Error 2

Hi @george-githinji ,

Clang doesn't support openmp in MacOS by default, and rkmh uses it extensively for threading. IF you install gcc (either with MacPorts or HomeBrew) then run make, it should work. You'll also need xcode installed. Sorry it is such a pain on Mac OS! I'm hoping to make it easier by putting things in homebrew or conda over the next few months.

Thanks for the response! I will compile it with gcc. It compile on our linux hpc but I ran on to a different issue
