Error updating bindgen

[amanuel2]

Based on the "rust" branch I get a string of errors. First error I got was exactly this issue, and I applied the patch myself exactly as specified in the lore.

Now I come onto this error trying to update bindgen after changing it to 0.65.1 as per one of the changes in the lore:

> cargo install --locked --version $(scripts/min-tool-version.sh bindgen) bindgen
    Updating crates.io index
warning: no Cargo.lock file published in bindgen v0.65.1
error: there is nothing to install in `bindgen v0.65.1`, because it has no binaries
`cargo install` is only for installing programs, and can't be used with libraries.
To use a library crate, add it as a dependency to a Cargo project with `cargo add`.

I even tried to hack it around as per so, but then got the error

>  cargo add bindgen                               ✔  1997  00:03:21
error: failed to parse manifest at `/home/aman/Documents/rust-linux/Cargo.toml`

Caused by:
  virtual manifests must be configured with [workspace]

Am I missing something entirely here?

Thanks for the report. There are a few things to note:

• The rust branch is archived, please see https://rust-for-linux.com/branches#rust.
• In mainline Linux we use newer versions of bindgen. Mainline or something close to it is generally what you want for Rust development.
• In newer versions of bindgen, bindgen-cli is the name of the crate that contains the CLI tool. Please see https://github.com/rust-lang/rust-bindgen/blob/main/CHANGELOG.md#changed-9 and https://docs.kernel.org/next/rust/quick-start.html#bindgen.
• I am not sure what were you trying to do with cargo add, but we do not compile the kernel using Cargo.
