I think at the moment most people who tried cannot build Sage on MacOS 10.15 with Xcode 11.1 (the latest one). Regarding gfortran, perhaps one can try installing Homebrew and use gfortram from there.
If you just need a working Sage, your best bet on MacOS 10.15 might be the one from conda-forge. https://anaconda.org/conda-forge/sage On Wed, Oct 30, 2019 at 10:57 PM Rob Gross <robert.gross.1...@gmail.com> wrote: > > Hi, > > I tried both upgrading to sage-8.9 and compiling from scratch, and both times > gfortran would not compile.
