How to compile on OSX?

[tiltmine]

Trying to compile this on OSX by just typing make, but getting the following:

$ make
c++ -O3 -std=c++11 -Wall -Wpedantic -pthread   -c -o omp/CombinedRange.o omp/CombinedRange.cpp
omp/CombinedRange.cpp:21:47: warning: suggest braces around initialization of subobject [-Wmissing-braces]

Using the following version of c++:

Sorry if this is obvious!

Try -std=c++14 or even c++17

[jdoerrie]

Try marking XoroShiro128Plus::max() and ::min() in omp/Random.h as constexpr.
