[Rcpp-devel] Getting different build commands on Linux vs. Mac OS

[Evan Biederstedt]

Maybe my Mac OS needs updating...possibly something with XCode, but it's
not clear how...

--- mac OS Sierra 10.12.6
--- CRAN R 3.4.3
---clang & gfortran

$ clang --version

Apple LLVM version 9.0.0 (clang-900.0.39.2)

Target: x86_64-apple-darwin16.7.0

Thread model: posix

InstalledDir: /Library/Developer/CommandLineTools/usr/bin


$ gfortran --version

GNU Fortran (GCC) 7.1.0

I will update once I have access to and try this on several other mac boxes
with different specs..

Thank you to everyone for the help.
