FreeBSD 13.2

hmmm this is very linux-specific code (it's only used for ALSA backend), I don't know why it would even go through this in freebsd..

[jcelerier]

is there a timerfd alternative there?

[yurivict]

Setting LIBREMIDI_NO_ALSA=ON gets rid of this compilation failure. It must be working through Jack.

---

The timerfd functions aren't available on FreeBSD because they are Linux-only functions.

[yurivict]

FYI: ALSA is supported on FreeBSD.

But libremidi now uses linusixms like timerfd in the ALSA code so I had to disable ALSA in the FreeBSD port.

FYI: ALSA is supported on FreeBSD.

oh, okay I did not know (or expect this) at all. And there isn't any timerfd shim for BSD?

[jcelerier]

I disabled it for now if timerfd is not available. Instead I'd like to consider using the native BSD MIDI APIs, I read about /dev/umidi and OSS but could not find much docs...

[jcelerier]

should be good on 4.1.0, please reopen if you still encounter issues!
