Problem with gfortran macOS Ventura

[silviacolumbu]

Hi,

I have updated my mac to Ventura 13.2 and I'm not able to run Rcpp. When I try to compile a cpp file through sourceCpp I get the following errors:

ld: warning: directory not found for option '-L/opt/R/arm64/gfortran/lib/gcc/aarch64-apple-darwin20.6.0/12.0.1'
ld: warning: directory not found for option '-L/opt/R/arm64/gfortran/lib'
ld: library not found for -lgfortran
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [sourceCpp_2.so] Error 1

I tried to install gcc to provide a new version of gfortran but without fixing the problem. Do you have some suggestions?

Thank you

I can only point you to the R on macOS documentation, I am not a macOS user myself. However, there are numerous macOS users among the Rcpp users so maybe someone else can pipe in. At a minimum it looks like you need to install (or update) the Fortran compiler and them possible the R setup in your ~/.R/Makevars file.

I am closing this as it is not really an Rcpp issue -- Rcpp does not use Fortran. I do feel sorry for the macOS users though; it was good when we had concise and up-to-date information by @coatless because apparently neither a two-trillion dollar company nor the R Core team member can do so in a way that normal humans understand.
