Issue compiling udpt onto a raspberrypi

[Kahloyx]

This is maybe a dumb issue or a mistake I made but I get this error code while trying to compile it via cargo build --release: cargo build --release Compiling tokio v1.1.0 Compiling serde v1.0.120 Compiling pin-project v0.4.27 Compiling pin-project v1.0.4 Compiling tracing-futures v0.2.4 error: unexpected selfparameter in function --> /home/oops/.cargo/registry/src/github.com-1ecc6299db9ec823/tokio-1.1.0/src/net/tcp/stream.rs:624:40 | 624 | pub fn try_read_buf<B: BufMut>(&self, buf: &mut B) -> io::Result<usize> { | ^^^^^ not valid as function parameter | = note:self` is only valid as the first parameter of an associated function

It seems that your compiler doesn't like something in tokio, which Rust version is being used? Try upgrading the compiler.

[Kahloyx]

I tried to install the latest version of the compiler but without success (no version found by the installer for an armv7l platform), the version of the compiler into the raspberrypi OS repo is 1.41.1, I tried reinstalling it but no success.

Tokio's current MSRV is 1.45, I would suggest cross compiling if the toolchain isn't available for Raspberry Pi.

[Kahloyx]

I'll see about cross compiling it asap, thanks for your time Le dim. 9 mai 2021 à 16:19, Naim A. ***@***.***> a écrit :
