osxcross VS cross

If you actually have MacOS device and can install Xcode and so on then you can proceed here and read the instructions.

Have you considered using a dockerized osxcross cross compiler toolchain in your CI? Granted it is a bit clunky to setup...

Technically it's possible, but possibly not legal:

> Please ensure you have read and understood the Xcode license terms before continuing.

According to the EULA you may only use the SDK on Apple-branded computers. But you can use Linux to cross compile to Apple.

is there a way to cross compile without vms? something similar to https://github.com/tpoechtrager/osxcross?

If you figure out how to get SDL working, one possibility is to develop on Linux, then use mingw-w64 to cross compile from Linux to windows, then use osxcross to cross-compile from Windows to OSX.

Thank you osxcross for creating the path forward

This is actually a solved problem, using osxcross[0]. The experience is honestly very smooth, and we don't require any apple proprietary binaries. The only thing apple-proprietary is their SDK (containing the header files for compiling, and tbd files for linking), which can be downloaded from apple's website (at least if you have a developer account), or from various GitHub projects archiving them.

To compile a program with musl on a glibc system you can use cross-rs!

I cross compile to Mac, bsd, windows, etc cross ... Works great for me with either docker or podman.

If docker is available for you, https://github.com/cross-rs/cross is another and reliable way to solve this kind of problem. I do use it regularly.

We are using https://github.com/cross-rs/cross.

There is some built-in support in rustc for cross-compiling, but getting the build to actually work can be tricky due to the need for an appropriate linker. Instead, we’re going to use the Cross crate, which used to be maintained by the Rust Embedded Working Group Tools group.

I have used cross before to cross compile from Linux to other Linux. It has a section on it's wiki about this. Maybe that could be of help.

You can use cross to build your application and copy the artifacts into an alpine armv7 container. It would also build faster due to using cross compilation rather than QEMU.

Looks like cross is the easiest way to get something cross-compiled but its Mac support is blocked behind building your own build image. Even that repo says that it might be broken.

Bonus: if you’re working with Rust and doing a lot of cross platform stuff, check out cross. It runs QEMU in docker so you can run tests on a bunch of different emulated targets easily- literally a one line setup, it’s kind of magical.

It's also not as naturally cross-compilable as Go, though that's partly a side-effect of not accepting being a semi-closed ecosystem to achieve that and cross exists as a stop-gap while things like cargo-zigbuild explore less drastic options.
