Support Apple M1

[odaki]

Hello, Olav Sørensen.

First of all, I want to thank you for your continuous development. I admire you and your project.

I recently bought a development machine with an Apple M1 processor. The macOS version you are distributing is working fine. I built it natively on arm64 so that it would run more optimally, and I tried to make it a Universal binary.

• Add a script to create a universal binary.
• Delete ".gitignore" that was left under the App folder
• Generate a dmg file for distribution.

You don't need to merge it, but I will tell you the work I did in the form of a pull request for your reference.

I have made the built binaries available in my repository. https://github.com/odaki/ft2-clone/releases/tag/v1.42-private

Thanks.

Pretty sure the .gitignore is needed in the MacOS folder, or else you won't get that folder when you do a pull of the whole branch (because it's empty), and thus the compiler can't output its binaries there.

[odaki]

Thanks for the explanation. I was thinking there must be a reason for this, but now I understand.

I'll try to create it in the build script with mkdir -p if it doesn't exist, what do you think?

[8bitbubsy]

That's a better solution than having the .gitignore file, thanks.

Will the universal binary compile on macOS Catalina on an x86_64 mac? I don't have an M1 Mac, and I don't want to merge stuff without testing it first.

Yes.

The build log is attached for your reference. build.log

I don't have an M1 Mac, and I don't want to merge stuff without testing it first.

I agree with your thoughts and want to respect them. If you are able to build on the M1 Mac, please support Universal binaries.

Please keep up the great work.

Thank you.

I will of course make a universal binary and support M1 if this works. =) So all I need is MacOSX11.1.SDK? I assume that SDL2.framework (latest version) is universal as well and works on M1 too?

It it very nice to hear that!

You will also need arm64 compatible clang, but if you are using Xcode 12.3, then you are ready for the MacOS11.1 SDK and clang.

Xcode 12.3
Build version 12C33

I assume that SDL2.framework (latest version) is universal as well and works on M1 too?

Yes, it works fine on M1 too.

As you wrote, SDL2 has been a universal binary since it was released late last year.

Alright, cool. I'll look into this later, maybe in a few days. Btw, I don't really want to merge your pull request, as I want to have different filenames, and I want to update the old macos script to fetch version number and make a DMG like your new one.

[alexmyczko]

odaki you going to create brew formulas?

[odaki]

@8bitbubsy You don't need to merge my works. Please follow your own rules, and keep it concise and consistent. I like your simple and clean programs and methods.

[odaki]

@alexmyczko I have no plans to make brew formulas. I'm a brew user and I like brew, but I don't understand how to write formulas.

[8bitbubsy]

I can't get it to compile on my MacBook Pro w/ Catalina using make-macos-universal.sh. It gives many errors about not finding include headers. Do I really need those SDK files? And where can I get them?

EDIT: I changed the x86_64 build to use MacOSX.sdk, and now it compiles.

[odaki]

You can get the old sdk by XcodeLegacy. https://github.com/devernay/xcodelegacy

I have now added the new make-script to the new v1.43 version of the FT2 clone released just now, and I also added the universal binary on 16-bits.org.

I also gave the pt2-clone the same treatment.
