OpenBLAS: some recent change in Macports broken finding OpenBLAS with Clang builds for some ports

[barracuda156]

Something very recently has broken OpenBLAS finding with clang builds for some port(s). See: ​https://github.com/macports/macports-ports/pull/20901

I tried to upgrade madness, which worked fine locally for me and worked on every system earlier for months: ​https://ports.macports.org/port/madness/details (well, okay, 10.6 Intel failed, it seems). Upgrade failed with:

Initially I attributed that to a recent commit to upstream: ​https://github.com/m-a-d-n-e-s-s/madness/issues/504

However, when I tried revbumping our existing version of madness, it failed identically. It also fails now on Sonoma for me locally. Building with GCC on 10.6 PowerPC works fine.

I have no idea what goes wrong. Could someone help here?

madness @2023.09.20 builds fine for me on Monterey x86_64.

Do your cmake logs say anything about why it failed for you?

Replying to ryandesign:

madness @2023.09.20 builds fine for me on Monterey x86_64.

Do your cmake logs say anything about why it failed for you?

The failure looks identical to what we saw on CI now.

I think this is due to libopenblas having /opt/local/lib/libgcc listed twice as an RPATH.

I guess this would have to be fixed in the openblas build but I have no idea how hard that would be, or you can pass -Wl,-ld_classic to the link.

(Or you can hand edit the library and change one of the references but I was in a hurry..)
