[Bug 1993183] Re: rustc linux kernel requirements

[Dimitri John Ledkov]

will it be available soon, at least from any ppa?

We are already packaging 6.1 kernel in PPAs as an unstable kernel, and
would like to enable rust examples in it.

Could we please have 1.62 anywhere please?

Title:
  rustc linux kernel requirements

Status in rustc package in Ubuntu:
  Incomplete

Bug description:
  linux kernel is adding rustc requirements.

  ideally we need a compatible version of rustc in $devel release, and
  last $lts, due to backporting of $devel kernels to latest $lts at
  point releases.

  Attempting the rust build in jammy today results in the following
  checks failing:

  
  sh ./scripts/rust_is_available.sh -v
  ***
  *** Rust compiler '/usr/bin/rustc' is too old.
  ***   Your version:    1.61.0
  ***   Minimum version: 1.62.0
  ***
  ***
  *** Rust bindings generator 'bindgen' is too new. This may or may not work.
  ***   Your version:     0.59.1
  ***   Expected version: 0.56.0
  ***

  Please update rustc to 1.62.0 in LL devel release and Jammy.

  Separately I will look if upstream kernel can upgrade to a newer
  bindgen, or if we need to request a historical bindgen packaging as
  bindgen-0.56 or some such.
