I'm not super familiar with what libraries look like on SUSE, but this probably means you need to do something like:

zypper install gfortran

gfortran is a system dependency that you seem to be missing. I think it's usually necessary for R, though, so surprising that you're missing it!

Hi Cole,

Thanks for your reply.

I've noticed that there are a few variations of gfortran like gcc48-gfortran, libdfortran3, libgfortran4, etc. Do I install all of these packages?

You probably just need the basic gfortran, I would guess. I would try just the one and see if that resolves :smile: On an Ubuntu server where I did a sanity check, there were about 600 different libraries that matched a search for "gfortran." I definitely don't think you need to (or want to) go through that whole list :smile:
