The list of blockers there implicates, * gcc * eclib * singular * ntl * gfortran * libgd * ecl * lcalc * fplll * giac all of which are available on Fedora 34, and pretty much everywhere. lcalc and fplll have the smallest number of entries in build/pkgs/$pkg/distros, with seven. While they may not all have been patched upstream (lcalc upstream was gone), I'm fairly sure they were all patched in Gentoo or sage-on- gentoo before they were patched in sage itself -- especially if I change that wording to "patched in a release." I'd also bet that Conda, Nix, and friends had it all sorted out before sage did. And all without wasting sage developers' time (except for those of us who maintain the distro packages, too, and who got to do everything twice). We are only concerned about gcc-11 support in any of those packages because we're supporting their SPKGs. But, for a while, the SPKGs have had superior alternatives. Delete the SPKGs and you might run into some other corner cases, but you certainly aren't going to hit gcc-11 build failures if you aren't building. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
