error: could not compile `librespot`.

On https://github.com/rust-lang/rust/issues/47493 I found that enabling lto might fix the problem so I tried that - the output is the same though. What could I try next?

exit status error: aborting due to previous error error: could not compile `librespot`. ``` On https://github.com/rust-lang/rust/issues/47493 I found that enabling lto might fix the problem so I tried that - the output is the same though. What could I try next?

Why are you building directly with rustc?

I am not directly building with rustc but with cargo instead. As suggested in #555 I supplied --locked but that did not change the behavior:

 cargo build --locked --release

Edit clarifying the language:

this was attempted to be built with 414383db18 and 06f5aa9c90. Both yield the same result as described above

Sorry, I don't follow - are you saying with a fresh checkout and --locked, github.com/librespot-org/librespot@414383db18 build fine, but github.com/librespot-org/librespot@06f5aa9c90 doesn't?
If so, then probably in all the version bumping b/w the commits, some Cargo.lock gremlins crept it..

the error message appears no matter whether --locked is specified or not. So the project does not build.

This is indeed a dupe of #555, please move discussion there.
