MSVC toolchain is not supported. Please use GNU toolchain

I was trying to debug Rust in CLion when I was greeted with the aforementioned

I updated my toolchain setting to use the suggested default as such:

How can I fix this issue and get CLion to be able to debug Rust code?

I did some searching but haven't found a simple answer (at at least one I can understand easily).

Solution

  • Error message is related about Rust toolchain, you need to use GNU based toolchain for Rust.

    If you haven't installed it yet, please make sure that you are choosing the valid gnu based toolchain for your environment, if you are not sure please read the Note section. You can install it via:

    > rustup toolchain install stable-x86_64-pc-windows-gnu

    Then the easiest way to solve this problem is setting this toolchain as the default Rust Toolchain:

    > rustup default stable-x86_64-pc-windows-gnu

    Note : Toolchain stable-x86_64-pc-windows is selected as an example; it's a solution for 64-bit Windows via stable channel, another toolchain needs to be used for different architecture(Details: please follow the official jetbrains guide from other answer), also you are free to use nightly or beta.
