Fix appears to be commenting out that include line, replacing it with #include <sys/event.h>

[ksss]

Thank you for using this library.

Sorry, I don't have FreeBSD environment. alloca seems function from libc in FreeBSD. https://www.freebsd.org/cgi/man.cgi?query=alloca&apropos=0&sektion=0&manpath=FreeBSD+13.0-RELEASE+and+Ports&arch=default&format=html

Can you please try the following modification? Please let me know if this works for you. Or PR is welcome.

I tried your fix and it gives me another error:

$ gem install kqueue.gemspec ERROR: Could not find a valid gem 'kqueue.gemspec' (>= 0) in any repository ERROR: Possible alternatives: hoe-gemspec, parse_gemspec

$ ls kqueue.gemspec kqueue.gemspec

[ksss]

Could you try $ bundle exec rake install ?

[hasandiwan]

Sure...

Hmm..., some constants seem to be undefined. I am not familiar with FreeBSD and do not have the time to work on it. Feel free to open a PR.

I'm now getting these undeclared identifiers -- help?
