Compile fails with error[E0596]: cannot borrow data in a & reference as mutable

Cargo normally only has compatibility with the current stable version of Rust. ( And vice versa, Cargo only knows how to run the current nightly version of Rust ) Why do you want to build Cargo 0.52 with Rust 1.47? I would love to understand your use case better? |

Thanks for the report but as mentioned you'll need to use the latest stable to guarantee being able to build the latest stable version of Cargo. |

@Eh2406 - I got it working, I used the latest downloadable, then compiled the version I needed. Bit of a round about way, but result was a-ok. As a completely different question - is there / should there be a way of building cargo/rust from bootstrap? |

There are many people who bootstrap rust. I believe the recommended method
is to start with https://github.com/thepowersgang/mrustc then use x.py to
build one version at a time.

I faced the bug with ubuntu 20.04 package, what would be the best option I have to install rust on a deb based distro ? |
|
Had to download a current rust and use that as a bootstrap. I haven’t done a full bootstrap yet with LibreELEC - on my list |
|
do we know what version we need as a minimum to avoid this bug ? |
|
It is the current or previous version |
|
you mean 1.52.0 and not before ? |
Using ubuntu 20.04, the build was failing with version cargo 0.47 / rustc 1.47. Following this discussion: rust-lang/cargo#9340 it appears that rustc 1.52 is the minimum version.
Hi Team,
Hoping you can help provide direction on enabling me to compile cargo on Ubuntu?
