Crash on running Go-SDL2 app through Rosetta

[SolarLune]

Hello!

Just wanted to see if anybody knew anything about this particular issue - I'm the creator of a productivity and organization app known as MasterPlan. It's written with go-sdl2, and has been working pretty well. Normally, I build on GitHub Actions through Mac OS 10.15 - you can see the setup script for the action here.

However, some M1 Mac users have reported that the app crashes on initial startup for them - looks like it's due to sdl_ttf; this is the result that a user got on attempting to run the program through the terminal.

MasterPlan.app/Contents/MacOS/MasterPlan ; exit;

I've done some research on what this issue could be, but I'm not 100% on the cause. Clearly, it's crashing during the ttf.Init() function call, but I'm not really sure what to make of that. It should be that Rosetta can handle all Intel code and translate it to ARM code on program first run, right?

I could use some direction in case somebody else has run into something similar before?

Hi @SolarLune, thanks for reporting the issue! I will check if I can reproduce this and fix it. Really cool to see an actual application that uses go-sdl2!

Hi @SolarLune, would it be possible for you to test the building for darwin/arm64 in the latest v0.4.x branch? I have added static compilation support for darwin/arm64. It seems to work on my Linux machine to cross-compile to the macOS and it runs on my Macbook Air M1 laptop. If it works for you too, I will add the tag for v0.4.26!

Hi @SolarLune, I have included static libraries for darwin/arm64 in the new v0.4.26 release. Let me know if it works for you!

Hello! Sorry for not getting back to you about this; other things have been going on. I'm looking to have somebody test this for me, but nobody's gotten back to me yet. Once they have, I'll let you know if the issue's resolved. Thank you for your patience!

Hello, so another M1 user tested and said it still isn't working. Just wanted to ask if I should need to do anything apart from static compiling on Mac?

Hi @SolarLune, was the executable statically compiled for darwin/arm64 and that wasn't working for the user?
