macOS M1 compiling error

[jianshu93]

Hello Team,

I have compiling error on my M1 MacBook Pro:

warning: unused variable: i --> src/me.rs:41:14	41	for (i, count) in self.quartet_pattern_counts.iter().enumerate() {	^ help: if this is intentional, prefix it with an underscore: _i

= note: #[warn(unused_variables)] on by default

warning: value assigned to target_read_seq is never read --> src/tag.rs:180:17	180	let mut target_read_seq = String::new();	^^^^^^^^^^^^^^^

= help: maybe it is overwritten before being read?
= note: `#[warn(unused_assignments)]` on by default

warning: value assigned to target_ref_seq is never read --> src/tag.rs:181:17	181	let mut target_ref_seq = String::new();	^^^^^^^^^^^^^^

= help: maybe it is overwritten before being read?

warning: metheor (bin "metheor") generated 3 warnings error: could not compile metheor (bin "metheor") due to previous error; 3 warnings emitted

Any idea why, it seems no problems on x86 linux.

Thanks,

Hi! Could you please give me more details about the command used for compilation?

Also it would be great to know your current environment for Rust development. Could you share the results from rustc --version and cargo --version?

Best, Dohoon
