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

Sun May 1 20:48:01 CEST 2022

Are you building with the min macos version flag set to 10.9 or higher? I think that is required to avoid the dialog when loading.

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.

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.
