I'm getting this error from doing cargo install c2rust, as it says in the README, or cargo install --locked c2rust.

The error is of course related to third-party libraries.

error[E0282]: type annotations needed for `Box<_>`
  --> /home/me/.cargo/registry/src/index.crates.io-6f17d22bba15001f/time-0.3.18/src/format_description/parse/mod.rs:83:9
   |
83 |     let items = format_items
   |         ^^^^^
...
86 |     Ok(items.into())
   |              ---- type must be known at this point
   |
   = note: this is an inference error on crate `time` caused by an API change in Rust 1.80.0; update `time` to version `>=0.3.35` by calling `cargo update`

For more information about this error, try `rustc --explain E0282`.
error: could not compile `time` (lib) due to 1 previous error
warning: build failed, waiting for other jobs to finish...
error: failed to compile `c2rust v0.18.0`, intermediate artifacts can be found at `/tmp/cargo-installFxdDcD`.

It is worth noting that v 0.19.0 builds from source just fine, so I propose that the fix could be as simple as releasing this to crates.io, which is still on v 0.18.0.

Maybe it's related to issue #1196

Me too. Tried also installing using --git but that also fails with another error.

At this point I changed my mind on switch to rust. This language has a long way to go for its entire ecosystem to become stable.

Please note that c2rust uses unstable Rust, don't throw the baby out with the bathwater. Stable Rust is way more stable, as it says on the tin.

Ok. This is the last time I bother you. Sorry but this is the way rust shows error messages. Always a little bit more detail and some hint on how to beg for a little bit more!
Here the version of error with RUST_BACKTRACE=full

$ RUST_BACKTRACE=full cargo install --git https://github.com/immunant/c2rust.git c2rust

Ah I ran into this issue last week as well, the fix for me involved the following:

Changing my previous:
ENV LLVM_LIB_DIR=/usr/lib/llvm-11/lib ->
ENV LLVM_LIB_DIR=/usr/lib/llvm-10/lib

I found this solution after looking through the part of c2rust-build-paths that failed, and it seemed like it wasn't finding llvm properly. I where'd llvm and found that the version had changed it seems.
