macOS: Generated template not building (opaque type declaration)

[KenjutsuGH]

Hi,

I ran

cargo generate ch32-rs/ch32-hal-template

and went through the prompts to create a project for a ch32v203f6p6.:

cargo generate ch32-rs/ch32-hal-template 
⚠️   Favorite `ch32-rs/ch32-hal-template` not found in config, using it as a git repository: https://github.com/ch32-rs/ch32-hal-template.git

🔧   Initializing a fresh Git repository
✨   Done! New project created /Users/ZZZ/Downloads/ch32-rs/v203blink

I then build the project, and get the following errors:

cargo build --release

error: could not compile `v203blink` (bin "v203blink") due to 2 previous errors

I am new to rust so I am at a total loss on what is wrong and how to resolve it.

My setup:

• macos Sonoma 14.5
• cargo -V: cargo 1.81.0-nightly (a1f47ec3f 2024-06-15)
• rustc -V: rustc 1.81.0-nightly (8fcd4dd08 2024-06-18)

Thanks for your report.
This error is not MacOS specific.
On Linux, I was on Nightly 1.79 and it was building, but after an update to 1.81, I now have the same error.
This is a ch32-hal error that should be reported there.

[romainreignier]

This is actually already reported: ch32-rs/ch32-hal#29

[romainreignier]

This should be fixed by using a fixed version of the nightly toolchain.
