Globally defined: DEFAULT_VERSIONS+=3D fortran=3Dflang will break all ports using gfortran-specific FFLAGS (e.g.-ffixed-line-length-none) and not using flang's replacements (e.g. -Mextend). In case of a math/lapack there are also incompatibilities with e.g. ETIME function:=20 gfortran requires it to be INTERNAL (default make.inc), flang - EXTERNAL (requires make.inc patch) etc. A suggested patch makes math/lapack to build using flang on amd64 only and passes all tests after that (see attached poudriere log). Other platforms should be unaffected and will continue to use gfortran. > devel/flang-clang has been marked broken hm, thanks, I've missed that somehow... I've just commited a patch for it (= see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D222254#c12). gfortran's FreeBSD issue is really annoying and affects virtually all scientific packages (e.g. Python's Keras, or recently added math/mlpack). With FreeBSD's movement from gcc to clang, flang is the only right choice i= n a long-term perspective. To avoid even more issues and incompatibilities in the future I'm encouragi= ng FreeBSD's ports maintainers to make this switch ASAP. Thanks! --=20 You are receiving this mail because: You are the assignee for the bug.=
