[R-SIG-Mac] gfortran: command not found

[Simon Urbanek]

AFACT he didn't say so, there was no response, just double-posting of the same question after is was answered.

The installer says:

The resulting compiler will live in /opt/gfortran and can be called with
/opt/gfortran/bin/gfortran

so it's advisable to have /opt/gfortran/bin on the PATH.

(Side note: the arm64 build of R uses the full path, but some people have been objecting to that since they wanted to use other compilers for the legacy Intel builds, but as I suspected that causes other issues, so I'll change that for the next release).

Cheers,
Simon
