You do not have OmniMidi registered afaik

@yurivict OmniMIDI/KDMAPI does not support FreeBSD. So inherently Wasabi cannot be compiled on operating systems other than Windows, macOS and Linux. I will keep this issue open to possibly remove KDMAPI completely when compiling for other OSes.

[yurivict]

1.0.1 still has this breakage. The FreeBSD port remains to be marked BROKEN.

That's because we have yet to add support for FreeBSD

[Kaydax]

@MyBlackMIDIScore Removing KDMAPI doesn't even solve the issue, XSynth itself does not support FreeBSD due to alsa-sys not being able to be compiled on FreeBSD. So even supporting FreeBSD will basically be removing two of the core features of Wasabi just to make it work, and that's assuming there isn't other stuff that isn't supported

[...] alsa-sys not being able to be compiled on freebsd [...]

Do you have a bug report for this? What is the reason?

FreeBSD does not support ALSA, it uses OSS. You can get some parts of ALSA working on FreeBSD, but thats with mapping it to OSS devices and isn't actually full ALSA

[yurivict]

FreeBSD does not support ALSA, it uses OSS.

No, both are supported.

Can you give sources on where it says ALSA is supported on FreeBSD? Because from all the searching I could find nothing on it actually working native on FreeBSD as the main sound driver and also found a lot of topics on it being really bad or broken

[yurivict]

Many projects work through ALSA. For example, audio/qtractor works through the ALSA backend, among others. I don't know what would qualify as "sources".

Sources as on websites or forums threads that say its possible to compile ALSA on FreeBSD. Of course ALSA programs can work on FreeBSD, as FreeBSD has a shim for them to work. But ALSA itself does not work on FreeBSD, and the alsa-sys library depends on the ALSA library as a hard dependent, meaning you need ALSA on the system to compile alsa-sys.

[yurivict]

I don't understand. For example, qBittorrent works on FreeBSD. Are there "sources" that are saying that yes, qBittorrent works on FreeBSD? There is the port and package net-p2p/qbittorrent that just works. Same with ALSA: here is the functional port for ALSA lib: https://cgit.freebsd.org/ports/tree/audio/alsa-lib It is API compatible with Linux libalsa.so that all apps use. There is also a kernel ALSA API that is naturally not supported on FreeBSD, but only libalsa uses it, and for all practical purposes libalsa should be sufficient.

[Kaydax]

Ok if you can get XSynth compiled and working on FreeBSD then I can easily fix the KDMAPI issue

[yurivict]

XSynth compiles fine on FreeBSD: https://cgit.freebsd.org/ports/tree/audio/xsynth

[yurivict]

Any chance to get this resolved and to make a new release with the fix?

Thanks, Yuri

[MyBlackMIDIScore]

Sure, sorry for the delay.

@arduano can you take a quick look at the PR for this so we can merge?

[MyBlackMIDIScore]

@yurivict Try the latest commit, it should compile under FreeBSD now with XSynth support. I won't make a new tag for it since there are no changes for the supported operating systems.
