I'm experimentally rebuilding rawhide with the not-yet-released GCC 15 to see if anything breaks, and to help write the porting guide. See https://fedoraproject.org/wiki/User:Dmalcolm/gcc-15 My test build with GCC 15 failed: https://copr.fedorainfracloud.org/coprs/dmalcolm/gcc-15-smoketest-3.failed/build/8476078/ whereas my test build with GCC 14 succeeded: https://copr.fedorainfracloud.org/coprs/dmalcolm/gcc-15-smoketest-3.failed.checker/build/8476510/ Looking at the failure logs e.g. https://download.copr.fedorainfracloud.org/results/dmalcolm/gcc-15-smoketest-3.failed/fedora-rawhide-x86_64/08476078-amg4psblas/builder-live.log.gz I see: checking for working installation of PSBLAS... configure_n: error: no. Could not find working version of PSBLAS. I'm trying to reproduce the failure; might be another instance of https://gcc.gnu.org/bugzilla/show_bug.cgi?id=118337 Reproducible: Didn't try
This appears to have been a gcc bug that was fixed. amg4psblas still doesn't build, but that's a different problem: At line 134 of file amg_d_base_onelev_descr.f90 (unit = 6, file = 'stdout') Fortran runtime error: Missing comma between descriptors (a,1xa,1x,f14.2) ^ Error termination.
