spin build error with wit-bindgen in hello-rust

[layeddie]

Got this error when running through the hello-rust example. Running on Mac Monterey.
Rust newbie.... not sure this is the right place to raise this....

Could you try updating your Rust to a more recent version please? Not sure exactly what our minimum version is but I don't think we can build with 1.56 any more. rustup update should do the trick; let us know if it still doesn't work with Rust 1.65.

(If you need to stay on 1.56 for other reasons, you might need to use the rustup toolchain feature to switch back and forth, sorry.)

Also... since this seems to relate to Spin rather than the Bartholomew CMS, is it okay for us to move it to the Spin repo? (Forgive me if I'm misunderstanding.)

Hi, Yes, whatever makes sense to you. Thanks for your response. Eddie Lay

Hi, is this okay to close?

[layeddie]

Yes, I didn’t get back to trying it out again unfortunately. If no one has reported a similar problem then it’s probably something in my setup. Thanks

Thanks! Please do reopen if you get round to having another go and still hit it.
