Undefined symbol in IO_Event.so #58

Closed piperswe closed 1 year ago

piperswe commented 1 year ago

I'm looking to try out the Falcon HTTP server, and it uses io-event via async. When I try to launch my server, I receive the following error:

ruby: symbol lookup error: /usr/local/bundle/ruby/3.2.0/gems/io-event-1.2.0/lib/IO_Event.so: undefined symbol: IO_Event_Interrupt_descriptor

IO_Event.so looks reasonable, except that the IO_Event_Interrupt_descriptor symbol is in fact undefined:

It looks like it's supposed to be an inline function (https://github.com/socketry/io-event/blob/main/ext/io/event/interrupt.h#L30). Perhaps adding static in front of inline will fix this? I'm not sure.

This is running inside a Docker dev container, based on Debian Bullseye.

Thanks I will take a look.
