Hi

I decided to try out Rust for ESP development.

As first action I installed Rust on my Windows 11 computer using rustup.

After that I created a new project using cargo and a template from ESP-RS.

Running this template I got the option to use VsCode Devcontainer which was what I aimed for.

The create process went well and I started VsCode in the newly created folder.

VsCode recognized the Devcontainer configuration ant started up a container.

It took a while but finally I was up and running.

So, my problem:
- The rust analyzer shows a error:

Code: Select all

cargo check failed to start: Cargo watcher failed, the command produced no valid metadata (exit code: ExitStatus(unix_wait_status(256))):

error: 'cargo-clippy' is not installed for the custom toolchain '/home/esp/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu'.

note: this is a custom toolchain, which cannot use `rustup component add`

help: if you built this toolchain from source, and used `rustup toolchain link`, then you may be able to build the component with `x.py`

VsCode footer also indicates this error.

There is another small but irritation error also.
The VsCode footer have a small "build" button. Press the button and you will be promted about you would like to build for "release" or "debug".
Whatever you select you will get this error:

Code: Select all

Executing task: scripts/build.sh release 

/bin/bash: line 1: scripts/build.sh: cannot execute: required file not found

 *  The terminal process "/bin/bash '-c', 'scripts/build.sh release'" failed to launch (exit code: 127). 
 *  Terminal will be reused by tasks, press any key to close it.

Any good advice how to correct this errors??
My Devcontainer is below.

Code: Select all
