Incompatibility io_uring backend with Linux 6.x and musl libc #107

Closed floriandejonckheere closed 1 year ago

floriandejonckheere commented 1 year ago

Polyphony raises the following error on require when using a Linux 6.x host and a musl libc-based Docker image (Alpine Linux). This doesn't happen when either using Linux 5.15 host or a glibc-based Docker image.

Seems to be an incompatibility within the io_uring backend. The libev backend works fine.

Should be fixed. I'll try to get a release out this weekend.
