@tissatussa

Probably the author pushed a commit that broke the build or something similar. I've just pulled the main branch (tagged 1.4.0) and it cleanly compiled and built on Debian 11 Bullseye, on Rust 1.55 (installed directly from the Rust-Lang website).

I forced pushed a fix to the 1.4 release. Strange that it would compile on windows but not on linux, might be an issue with the cargo version because the CI also runs ubuntu-latest and it seemed to pass.

Let me know if it works for you

[tissatussa]

now it compiles and runs OK ! only thing is the version number : it still has 1.4.0 ..

[MitchelPaulin]

I decided to just update the 1.4.0 release directly rather than make a 1.4.1 since the change was so small. Happy it's working!
