Hello,

I am trying to compile the application on an OrangePi Zero Plus since there are no pre-made builds available.

When compiling it fails with a few warnings / errors:

root@dapnet-trx:/opt/dapnet/UniPager#` cargo build --release

Compiling unipager v1.0.3 (/opt/dapnet/UniPager)
error: cannot find macro select! in this scope

109 | select! {

71 | | ( $( $key:ident: $value:expr),* ) => ({
72 | | let mut status = $crate::status::STATUS.write().unwrap();

80 | | }

Then the warning "trait objects without an explicit dyn are deprecated" repeats a number of times, before it fails with:

10 | 0...127 => byte,

error: aborting due to previous error

error: Could not compile unipager.

Is there an "easy" way around this issue, or will it require a code update?

Thanks...
