[R-pkg-devel] Problems with devtools::build() in R

[Simon Urbanek]

This thread went way off the rails and was cross-posted so the solution is on R-SIG-Mac.

It was simply wrong Fortran with wrong R - installing latest R and Fortran (from CRAN or https://mac.r-project.org/tools/) is the easiest way to solve the problem.

Note that R binaries and tools go together so if in doubt, just go to CRAN and follow the instructions.

Cheers,
Simon
