I am trying to produce a n R environment on clean new Catalina installation (in a VM). The R binary installer and RStudio work. Then, I installed clang7, and that seems to work also. gfortran, however, is a problem. The 4.2.3 version (still in the tools folder on CRAN) is 32bit only, so it does not work on Catalina. 6.1 from https://github.com/fxcoudert/gfortran-for-macOS/ cannot be installed, the installer tells that it is incompatible with this version of macOS.
Is there a workaround? Can I find a version of gfortran which will compile packages containing Fortran code? (I stumbled on classInt). I also tried gcc@7 from homebrew, but could not get it to run either. _______________________________________________ R-SIG-Mac mailing list R-SIG-Mac@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-mac
