There was a problem hiding this comment.
It is not related to this PR, but I think we can do some micro optimization here:
- Let's change the list to a set for fast check
- Initialize the set before for loop

Indeed, that makes sense. I'll take that up in a new PR!

Description
These arguments are inserted by Meson when compiling on a macOS machine on a few occasions; see numpy/numpy#28642 for greater discussion. This PR filters them out, as
wasm-ldraises errors if it sees them.This PR does not address the original issue, i.e., as to why Meson adds these arguments. The apparent cause is the use of shared libraries,
libopenblas.soin this case + the fact that we are "mocking" cross compilation in a way through pywasmcross and therefore Meson isn't smart enough to not add them. This PR is not strictly required; however, this PR is useful in its own right, as it helps compilation succeed on macOS on some occasions.Reference
