Describe your issue

The build fails with ModuleNotFoundError: No module named 'setuptools' error, even though it appears that setuptools module is available with chaquopy package repository? I already tried it with different python versions, but the build fails with the same error.

Maturin is a build system for Rust. Since you won't actually be building any Rust code on an Android device, there's no useful purpose in adding it to your app.

Are you doing this because you actually want some other package? If so, please let me know which one.

[adi-shankara]

Indeed, I want to use the gl-client package. Had it there until it complained about maturin not found, and then setuptools not found. I removed gl-client package to narrow down on the culprit, but it seems you're suggesting that it is actually maturin that is causing this issue? What is the solution in that case? Please advise. Thanks for your prompt response.

[mhsmith]

gl-client contains Rust code, so it would have to be built into a wheel file.

If you'd like to try doing this yourself, the instructions are here. However, our package build tool doesn't currently have working support for Rust – see #1030 for details.

Or maybe you could use something else instead of gl-client, but since I don't see any documentation explaining what this package is or what it's for, I can't advise you on that.

If anyone else wants this package too, let us know by clicking the thumbs-up button above.
