rtp v0.1.0 compilation?

[ghost]

Hello and sorry if i'm posting this in the wrong repo. I'm trying to compile this with:

OS - Ubuntu 18.04.5 LTS Cargo - 1.49.0 (d00d64df9 2020-12-05) rustc - 1.49.0 (e1884a8e3 2020-12-29)

and command: cargo build --release with these packages installed already (and up to date system):

• libnice-dev
• libssl-dev
• clang

When I run that command to build, I get the following error:

error[E0282]: type annotations needed
   --> /root/.cargo/git/checkouts/rtp-23e67d7854ed482f/1444b3c/src/rfc3711.rs:476:19

Any idea how i can go about solving this? Thank you very much

Huh. Could you try with an older version of Rust? Maybe there was some subtle change to type inference in one of the more recent releases which inadvertently broke that piece of code. iirc 1.39.x is what I tested with, so that one should definitely work.

That worked perfectly! Thank you very much for the quick response. I suppose for anyone else who runs into this, simply run:

rustup default 1.39.0

then re-run the build. Works flawlessly. Thanks again!

rust 1.48 works too
