I'm building Sage 8.4 from source on my new laptop (Dell XPS 13, latest up-to-date Fedora 28). It goes fine until it get to OpenBLAS, where it dies with the error msg: "libgfortran.spec: No such file or directory."
I know math and computers, but I don't know Sage/OpenBLAS/Fortran at this level. So I need help.
Thanks in advance!
