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

Versão do XcodeSistema operacional mínimo necessárioSDKArquiteturaDestinos
de implantaçãoSimuladorSwift

Xcode 12.4 macOS Catalina 10.15.4 (Mac com processador Intel)

macOS Big Sur 11
(Mac com Apple Silicon) iOS 14.4
macOS 11.1
tvOS 14.3
watchOS 7.2
DriverKit 20.2 x86_64
armv7
armv7s
armv7k
arm64
arm64e
arm64_32 iOS 9-14.4
iPadOS 13-14.4
macOS 10.9-11.1
tvOS 9-14.3
watchOS 2-7.2
DriverKit 19-20.2

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
