sort of a follow-up to https://github.com/Lakelezz/audiopus_sys/issues/1 as that issue is stale,

attempting to cross-compile to arm systems works, until the linking stage where it produces this error:

target/armv7-unknown-linux-gnueabihf/debug/build/audiopus_sys-96ea5a29564c45f6/out/lib/libopus.so: file not recognized: file format not recognized

That error often means it has been compiled for the wrong target. This may be due to the wrong target selection, something I tried fixing but to no luck.

@Lakelezz I suggest to use cmake toolchain instead of hacking with autoconf shit. It is simple as https://github.com/DoumanAsh/opusic-sys/blob/master/build.rs#L44-L85

On side note I'd like serenity to cross-compile with voice enabled :(

But it works just fine in cross
