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!

Oops, my bad! Turns out I didn't have gfortran installed correctly, re-install fixed the problem ...

Could you please provide more details for those of us having the same problem? How do you install gfortran incorrectly? It's installed via the package manager 'dnf' in Fedora.

Using built-in specs.
COLLECT_GCC=gfortran
COLLECT_LTO_WRAPPER=/usr/libexec/gcc/x86_64-redhat-linux/8/lto-wrapper
OFFLOAD_TARGET_NAMES=nvptx-none
OFFLOAD_TARGET_DEFAULT=1
Target: x86_64-redhat-linux

Thread model: posix
gcc version 8.2.1 20181105 (Red Hat 8.2.1-5) (GCC)

Thanks!

In my case I had gcc installed but not gcc-fortran. I think either you should go with SAGE_INSTALL_GCC=yes and ask sage to completely install gcc or go with SAGE_INSTALL_GCC=no you install all gcc component yourself. Because I only relied no SAGE to install gfortran, I think that is how it failed.
