Build script throwing subprocess "Exec format error"

[ghost]

Hello! There's a bit of an issue with the build process, and the way the bundled cargo is called from aero.py seems to disagree with subprocess on my system for some reason.

Results of ./aero.py --test:

• python3 --version: Python 3.9.6
• Host Operating System: macOS Ventura 13.0
• Host Architecture: aarch64-darwin

note: I'm well aware aarch64-darwin isn't officially supported, but it's one of the few (if not the only) mainstream consumer platform using the aarch64 architecture, and at least the only aarch64-based device I have access to for testing.

update: aero.py build system is not functional on aarch64 - PR #81 will likely fix architecture support, upon which this issue can be closed.

the issue here is that the prebuilt rust/cargo is compiled for x86_64-linux, you will have to figure out a way to compile all of that yourself if you want to use it on aarch64-darwin

[jwpjrdev]

why does aero need a seperate rust/cargo installation in place of the system default?

[48cf]

it's for cross compiling iirc

@jwpjrdev I'm not super familiar with the architecture of this project, but I think the whole unpacking a remote version of cargo from a Google Drive archive is just a band-aid fix implemented at some point that needs to be replaced (but again take this with a grain of salt).
