Freebob/FFADO for Gentoo

audiodef · Posted: Sun Dec 14, 2008 9:48 pm Post subject: Freebob/FFADO for Gentoo

Is Freebob going to make it into Portage in the near future?

i see this bug:

https://bugs.gentoo.org/show_bug.cgi?id=206001

but i don't see the aforementioned sys-libs/libfreebob

edit: facepalm. but there is an ebuild there. :lol:

Humour in subject lines. Great for releasing steam. :-P

Ok. Trying to get freebob and firewire into jack-audio-connection-kit-0.116.1. I downloaded http://freebob.sourceforge.net/index.php/Main_Page and did a straight-up compile. I can see the libs in /usr/local/lib. I even made symlinks in /usr/lib. But jack-audio-whereisit-kit still says FALSE to compiling with freebob and firewire.

What do I need to do?

Note to self: I'm surely gonna kick myself when someone points out something REALLY obvious. :-P

That's interesting. What's also interesting is that upon sticking it into my local portage tree myself, it says it's masked by the x86 keyword. Put it in my package.keywords and it emerges.

I just posted this: https://forums.gentoo.org/viewtopic-t-718190-highlight-.html

And now I'm thinking perhaps jack-audio-connection-kit should have a "freebob" use flag so that it will pick up freebob/firewire drivers if that flag is enabled.

did you apply the diff to the ebuild from the bug that i posted in your other thread?

I actually just found that using the ebuild and then re-emerging jack-audio-connection-kit lets jack pick it up during configure. Yes!

So if that's done, should I still apply the diff? (and how, do I, btw)?

if it works without, i'm going to say no.

but to patch ebuilds you would do something like this:

This should really go in U.S.

Btw, jackd won't start with realtime. How much do you know about starting jack? I get:

audiodef · Posted: Mon Dec 15, 2008 9:39 pm Post subject: The Gentoo Freebob Thread

I hope I'm not duplicating this effort - I searched and didn't find a thread on these forums dealing with Freebob. It seems like, from those who've gotten it to work, an answer to certain prayers. For the rest of us, those prayers continue to float along where the sun don't shine.

Let's try to change that. I have ONE remaining Windoze workstation in my household, and that's only because my MOTU MIDI patch bay, Mackie Onyx/Firewire mixers and Cakewalk Sonar need it. Sonar I can find suitable subtitutes for in Linux - boy, can I. But until I can use those mixers with their Firewire cards, I'm stuck with Windoze.

I SO want to chuck Windoze.

I'm going to post the things I try, whether it works or not, in the hopes it gives me a single location to keep track of what does and does not work. I hope to find a solution. I hope others will contribute. And I hope this thread will be useful to others.

I also hope to not have to worry about money someday, to have a nice house in the country with no neighbors closer than an acre away, world peace, universal human intelligence, yadda, etc., but those are beyond the scope of this thread.

Here's a thread that inspired this thread. https://forums.gentoo.org/viewtopic-t-718166-highlight-.html. I'm not cross-posting or creating duplicates. In the other thread I only wanted to know whether there were plans to introduce Freebob into portage.

Thus far, I have done this:

From http://freebob.sourceforge.net/index.php/Main_Page you can click on "Building and Installing" and look for a link to the tarball on the Sourceforge page that appears. I didn't have any trouble compiling this, but when I went to compile jack-audio-connection-kit, it didn't see the freebob drivers. I put symlinks from the files in /usr/local
/lib to /usr/lib, but no go.
Then I found an ebuild for Freebob (courtesy of bunder): libfreebob (https://bugs.gentoo.org/show_bug.cgi?id=206001). Hats off to Trinine for creating this ebuild. I created an overlay and this compiled fine. jack-audio-connection-kit then compiles and picks it up.
Qjackctl would not let me start jackd; however, using a command line as root allowed it to start. HOWEVER, this revealed other problems, and this is where I'm now stuck.

Not owning a firewire audio device myself I cannot really help with this. But if you want to try ffado, there is an ebuild in pro-audio overlay.

Thanks for the link, gimpel.

Did I overlook it? I see freebob in the ebuild list, but nothing called "ffado".

Until now there was only a live scm -9999 version, but I just committed libffado-2.0_rc1.ebuild - just sync the overlay.

Feel free to test!

You'll need to unmask sys-libs/libraw1394-1.3.0* from portage, or the 2.0.0 from proaudio.
And of course make sure your device is listed as supported or, well, at least as unknown: http://www.ffado.org/?q=devicesupport/list

Yeah, I'm using Onyx mixers with Firewire - those are listed.

Will check it out in a bit. Thanks again!

I picked up the pro-audio overlay and emerged libffado, then re-emerged jack-audio-connection-kit. But I don't know which driver to use when I start jackd. If I use dfreebob, jackd says it's unknown. Ditto dfirewire. I re-emerged qjackctl, but that didn't changed anything.

What'd I miss?

By the way, I just tried to compile rt-sources. I copied my config over from my working kernel, went into menuconfig, looked around, was satisfied all was well, and got this on make:

Had the same or a similar problem trying to compile rt-sources 2.6.26.3-r3.

I'm just gonna have to pass until I can figure out why these kernels are not compiling. More versions backwards and it's no good for my udev setup.

gimpel · Posted: Wed Dec 17, 2008 9:12 am Post subject:

The problem with rt-sources should go in a different thread. Or, as rt-sources is nothing else but vanilla patched with the -rt patch, you should check the linux-rt-users mailing list. Make sure the problem hasn't been reported yet, and if it hasn't, report it there.
You can find info about -rt in general and links to their list on http://rt.wiki.kernel.org/

Your error with 2.6.25 could be caused by using CONFIG_SLUB=y. See if it works with with good old SLAB.
Be warned that 2.6.25-rt is almost unusable for MIDI work.

--------
As for ffado, the correct way to install it, is to emerge jack-audio-connection-kit with USE="ieee1394" (may it be a patched ebuild from b.g.o. or the one in pro-audio). I could only compile-test it, the jack driver ends up as /usr/lib/jack/jack_firewire.so

For libffado I had problems with USE="mixer" as it refuses to find some dbus/qt python module. Not sure if this is caused by the qt-4.5 snapshots I use, or if it's a problem in the build setup. Reports about success or confirmation of the problem would help.

It looks like jack-audio-connection-kit is already compiled correctly, as jack-firewire is in /usr/lib/jack. So I tried jackd --realtime -d firewire (or even jackd -d firewire) and got

I do have firewire support enabled in kernel. I just read the README word by word, but I'm still getting the same "firewire not found" error.

lmms doesn't have anything to do with it.

It just pulled in libffado, for which I disabled the mixer use flag.

Is there a command similar to lspci and lsusb that scans firewire ports for attached devices? I'd like a way to scan my firewire bus and make sure I can actually see the mixer attached. The firewire card shows up in lspci but doesn't tell me what's plugged into it.

Here's my kernel config, just in case I missed something:
