It looks like this might be the upstream bug?

Yes, that looks like the bug. A common problem with many ports on Big Sur and later. (Any software using libtool and relying on undefined symbols.) Looks like gcc went a slightly different direction with the fix from the one that we usually apply, which is the one I described in the upstream libtool bug report which the developers of libtool have yet to acknowledge.

Ah, very interesting. Thanks. Is this something that'll be blocked indefinitely until it's done upstream, or is it something that can be patched in the port files?

comment:4 Changed 5 months ago by ryandesign (Ryan Schmidt)

We should update arm-none-eabi-gcc to the latest version, which is 10.3.0. Maybe that already incorporates the fix. If not, or if updating is too difficult, we can apply a patch.

Note that "we" means any interested volunteer. This port has no maintainer.

Ok, I can give it a shot. Just so long as you don't mind me asking questions on this bug if I get stuck

comment:6 Changed 5 months ago by hpux735 (William Dillon)

So I see your patch, and that makes sense. Where I'm a little stuck is that the portfiles for the cross tools are all made with that tcl script, and I'm not really familiar with how to "hook" into it. Do you have any advice?

Bumping this because I'd like to use it, but I'm just not smart enough about how compilers work to know where to begin on patching it as was discussed above. I'll put a bounty of US$20 out there for anyone that can get this installable on the M1 before the end of May 2021.
