Description Chris Pritchard 2023-12-11 23:14:13 UTC

lapack fails to build when testing for fortran during the configure phase with bfd as a linker.

Resolved by turning off LTO.

main.c:(.text.main+0x15): undefined reference to `VerifyFortran' seems to be the main culprit!

note wrt linker: We have to use bfd here because clang->gfortran (we don't have flang yet). with lld, we get the standard 'undefined reference to main' thing because lld doesn't support gcc lto.
