Build failure on aarch64

The build on F37 / 36 went fine for x86_64 but fail for aarch64 on F37:

I'm afraid, aarch64 is not supported, right now. Sorry :(

The problem shown in your log might be easily fixable. I'll try in a couple of days. And very basic GUI and editing/playback functionality should work, then.

But any audio effects or synthesizers and other cooler features depend critically on my integrated JIT compiler for plugins. Currently, this can only produce x86_64/32 machine code. Some years ago, I started adding a compiler backend for ARM processors (32 bit). It's not complete and I never worked on aarch64.

Since I always wanted raspberry pi support, I might look into it again. But no promises, right now.

Ah, OK, thanks for this news. I will disable the aarch64 build then :)

It actually happened. Tsunami now has proper support for aarch64. The basic c++ program builds AND also the plugin JIT compiler now has an aarch64 backend.

Successfully tested on an M1 MacBook, and Raspberry Pi 3 (64bit) - although I would not call it usable on the Raspberry Pi.
