Honestly, I don't know. I've not looked into specific versions of which Xcode can compile what. I basically just follow the normal upgrade cycle of keeping Xcode up to date with whatever macOS version I currently have. I don't care to spend much more headspace on it than that!

At some point, I couldn't build for i386 (I think some version of Xcode 10) so I removed building for x86_64. The same happened when I upgraded to some version of Xcode 12, I think, which included the SDK which includes compiler support for arm64.

I assumed I couldn't build i386 some time when I was on macOS 10.15 but I didn't write it down. If you want to spend the time for an answer, probably read through the Xcode release notes: https://developer.apple.com/documentation/xcode-release-notes. 

If you want to download and try different Xcode version, there is a handy site to the downloads provided by the Apple Developer portal:

https://xcodereleases.com

You will need a developer account to access them.

Damn, double checked and tested. Using XCode 12.4 on Catalina, I was able to compile else with a fat binary for both 32/64 bits, see --> https://github.com/porres/pd-else/issues/1241#issuecomment-1114263525

Back on Mojave, I downloaded 0.52-2 32 bits and tested the externals, it worked!

I can see it shouldn't, it really makes sense it should build or work, I should have known better and expected a failure and be amazed when it first compiled because it doesn't make sense, but it's happening.

Also, I can't build for arm64...

Anyone can help me solve the mistery?

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?
