Could not compile esp-wifi (lib)

[liyang8246]

Hello, I encountered some problems during the compilation process and I don’t know how to solve this，and I haven’t found any related issues. My English is not good,forgive me.

cargo build

My operation process：

first I set up environment follow rust-on-esp-book

cargo generate esp-rs/esp-idf-template cargo

add to 'cargo.toml'

esp-wifi = { git = "https://github.com/esp-rs/esp-wifi", rev = "1b3c3fc", features = ["esp32c6","ble"]}

edit .cargo/config.toml and cargo.toml

Then run "cargo build" and an error will be reported.

I'm a newbie in embedded rust,I don't know how to solve it, thank you

Hi, @liyang8246! You are mixing std crates with no_std ones.

We have support for both directions. For std we have crates with names like esp-idf-XXX (the idf in the middle is important here). For no_std it's esp-XXX. For more information, please look at Overview of Development Approaches.

In your case, you've created an std project via esp-idf-template and you are trying to use it together with esp-wifi, which is no_std. If you want to experiment with esp-wifi, use esp-template instead.

If you are a beginner in embedded rust, starting with repository examples might be a better way.
For no_std you could try these examples esp-wifi or esp-hal.
For std esp-idf-hal or the all-in-one beast rust-esp32-std-demo.

wokwi might be another source of examples (both no_std and std).

Thank you so much. I already know where I went wrong. Thank you again, otherwise I would never understand it.
