Re: [sage-devel] #32532 - removing gcc and gfortran spkgs

I have at least one close user/tester that builds sage-on-gentoo on a gentoo prefix (on a debian machine I think). Pretty much every beta/rc release get built and tested. I used to work on gentoo-prefix on OS X for a while. I should try it again someday but I don’t feel like my little macbook

Re: [sage-devel] #32532 - removing gcc and gfortran spkgs

Hi Matthias, Since Fortran is pretty central to this discussion, any chance you could give a quick overview of the extent to which Sage depends on Fortran in 2021? I was reading about pyodide [1] recently and they had to work very hard to build scipy for webassembly without using Fortran. I

Re: [sage-devel] #32532 - removing gcc and gfortran spkgs

I think my only concern with this is (g)fortran. The C/C++ compiler situation seems pretty stable, but doesn’t the fortran problem still exist? I do not use any package managers on my systems, so home-brew and the like aren’t useful to me. > On Sep 23, 2021, at 15:17 , Dima Pasechnik

Re: [sage-devel] #32532 - removing gcc and gfortran spkgs

I presume that this is not an issue for linux, but maybe I'm wrong about that. In any case, I'm concerned about OS X. - How well tested are the various standalone Fortran options for OS X? I mean, how well tested are they for building Sage? Gfortran coming from homebrew is already included in

Re: [sage-devel] #32532 - removing gcc and gfortran spkgs

As someone who contributed to those (and literally created the gfortran package when I pushed for enabling clang support on OS X) I welcome their demise. I’ll review their removal with pleasure if you need it. François > On 24/09/2021, at 10:17, Dima Pasechnik wrote: > >

https://trac.sagemath.org/ticket/32532 proposes to remove these packages as not needed, and a huge time sink for everyone involved. Rationale: nowadays every platform that Sage supports has said tools (or their equivalents - e.g. clang/clang++
