OpenBLAS: gfortran 11 ARM-darwin (Apple M1) build failure

We are seeing an openblas build failure (in Homebrew: https://github.com/Homebrew/homebrew-core/pull/74843#issuecomment-832845395) with the latest gcc/gfortran 11.1 port to Apple M1 (ARM-darwin). The failure is:

The compiler appears otherwise functional, so I think it’s specific to OpenBLAS. The problem is the -Wl,-rpath,,loader_path argument that is passed (twice), and I do not understand where it comes from.

The compiler driver itself can, in some circumstances, pass -Wl,-rpath,@loader_path which is a valid option. But somehow it seems that this @ gets mangled into a , making the whole thing invalid.

I haven’t managed, however, to find where in OpenBLAS build machinery, this could be happening. Can someone point me in the right direction.

Heh. So now I have the added superpower of halting compiler deployment ? Hopefully #3223 fixes it without new side effects. ( I realize now that it is basically the same as your proposal, just using a different character for the replacement - too busy with completely unrelated work yesterday)

Try setting MACOSX_DEPLOYMENT_TARGET=11.0 this is probably a bug in xcode

Has this been resolved? Seems to be getting similar error.
