Only include metadata for non-dynamic libraries in rustc-dev #105609

bjorn3 · 2022-12-12T12:54:48Z

The actual object code should be linked from librustc_driver.so, which is still included in rustc-dev. This saves on download time and disk usage.

Fixes #103538

For anyone landing here with an error like this:

  = help: try adding `extern crate rustc_driver;` at the top level of this crate

If you add extern crate rustc_driver and then get an error like this:

then you need to do rustup component add llvm-tools.

Only include metadata for non-dynamic libraries in rustc-dev The actual object code should be linked from librustc_driver.so, which is still included in rustc-dev. This saves on download time and disk usage. Fixes rust-lang#103538

Reading this [rust-issue] it seems that we have to link against rustc_driver. The [clippy.nix] expression already does something similar Of the 4 executables found in the result of building rustfmt only rustfmt and git-rustfmt needed to be linked. The other worked without linking to rustc_driver.
