Hello, All:
I'm getting "clang: error: unsupported option '-fopenmp'" when
trying to build "https://github.com/helske/bssm"; under macOS 10.14.14
with R 3.6.0; see below.
What do you suggest?
Thanks,
Spencer Graves
p.s. I assume I have to install compiler(s). However, I've so far been
unable to find instructions that are sufficiently current to convince me
I might not do more harm than good following them.
