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p.s. Helske told me he thought my compiler was out of date. 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.
