You cannot build for i386. Support for that arch was famously removed in macOS 10.15 and those versions of Xcode which use its SDK, probably version 10 or so. Modern fat libs arm64 and x86_64.

I have a fork of pd-lib-builder which supports arm64 & universal builds on macOS. The PR has been sitting for some time but we have been using it successfully for a few projects for some time now:


To build for arm64, you need a new enough Xcode (12.2 I believe) and that's it. You can cross-compile on an x86_64 machine for arm64 and vice-versa.

So, I now have a partition with Catalina (10.15.7) and Xcode 12.4, which is the last version catalina accepts. 

According to https://developer.apple.com/pt/support/xcode/ I believe 12.1 could have been possible already. 12.5 needs Big Sur. Here's a table from the link

It says it can build for 'arm64' alright, but I tried creating a fat binary for both intel and M1 as I was doing in my monterey partition and didn't succeed. I'm using pd-lib-builder, verdsion 6.0, so I did:

make install objectsdir=../ arch="i386 x86_64" extension=d_fat and that works just fine


but...


make install objectsdir=../ arch="arm64 x86_64" extension=d_fat fails miserably, this is what I get



/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include/sys/cdefs.h:807:2: error: Unsupported architecture

#error Unsupported architecture


What should I do?

My attempt here is to be able to build a binary for fluidsynth~ that works for a wide range of OSes

thanks
cheers

I guess I can install catalina on a partition, but I was hoping to use
pdlibbuilder in an easy way, is it possible?
