[PD-dev] [PD] how to compile externals for apple silicon?

Sun May 1 18:14:36 CEST 2022

Thanks Dan. I have a developers account, that's how I got XCode 12.4 - you
taught me that a couple of years ago ;) - and I linked to an apple site
that said it'd be able to compile for arm but it failed. One way or
another, I think I can give this up as I'm not sure my solution is
finding a system older than monterey to build for mojave to monterey and
offer a fat binary for intel and arm.

Regarding building a 64 bit intel external that works in OSes from at least
mojave to monterey, this is already possible when building in mojave, but
newer versions of macOS will complain it ain't safe and it's a hassle to
allow it to load (I mentioned this in the other "building fluidsynth~"
thread). It seems better to just solve this issue, but even so, I have
other issues I need to figure out as I also mentioned in the other thread.

Thanks again!
