Hi @rochacbruno ☕ 👋

When I run cargo install marmite on my Ubuntu 24.04 LTS version is fails with

   Compiling marmite v0.2.4

For more information about this error, try `rustc --explain E0716`.
error: could not compile `marmite` (bin "marmite") due to previous error
error: failed to compile `marmite v0.2.4`, intermediate artifacts can be found at `/tmp/cargo-install0k2SBf`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

Do you have any idea about how to resolve this?

Hi @rochacbruno ☕ 👋

I've got an older version of cargo (though its the default one shipped by apt-get with 24.04.1 LTS):

# cargo --version
cargo 1.75.0

# cat /etc/issue
Ubuntu 24.04.1 LTS

# apt list -a cargo
Listing... Done
cargo/noble-updates,now 1.75.0+dfsg0ubuntu1-0ubuntu7.1 amd64 [installed]
cargo/noble 1.75.0+dfsg0ubuntu1-0ubuntu7 amd64

I pushed a fix 43544d1

will be part of the next release.

For now you can try:

cargo install --git https://github.com/rochacbruno/marmite/

To check if issue has gone.
