The July stage 4 tarball is now available and has some nice additions:

jack-audio-connection-kit was upgraded from 1.9999 to 2.9999 with the dbus and mixed use flags.

Qjackctl now uses jackdbus by default.

Cadence binaries were installed. You can now use either Qjackctl or Cadence to control JACK state and connections.

Renoise demo was installed.

Acrobat Reader was installed (documention for various programs sometimes come in PDF).

I'm thinking of using genkernel in the stage 4 tarball for Gentoo Studio, with the goal of completely automating the install process. I'm ambivalent because what I really like about Gentoo (and Gentoo Studio) is the ability to exactly match kernel with actual hardware used. This is Gentoo Studio's "schtick" that differentiates it from other Linux audio distros. That, and the fact that Gentoo is a source-based distro that can tweak compile options to match users' exact wants/needs.

So what are your thoughts on genkernel in Gentoo Studio?

audiofef, just for the educational experience for my first time I didn't use your stage4 but actually went from scratch instead (mostly all fine so far).
I'm trying to use the Cadence binary though and I get this when I try to launch it:

Code:
Cadence self-contained executable 1.0, based on UnZipSFX.
unzipsfx:  cannot find myself! [Cadence]
Using Tray Engine 'Qt'
Traceback (most recent call last):
  File "/usr/share/cx-freeze-common/initscripts/Console3.py", line 27, in <module>
  File "./build/opt/cadence/share/cadence/src/cadence.py", line 37, in <module>
  File "./build/opt/cadence/share/cadence/src/shared_canvasjack.py", line 28, in <module>
  File "./build/opt/cadence/share/cadence/src/patchcanvas.py", line 28, in <module>
  File "ExtensionLoader_PyQt4_QtSvg.py", line 11, in <module>
ImportError: libQtSvg.so.4: cannot open shared object file: No such file or directory


Do you have any idea what I am missing? I spoke to the creator of it and he said it is libqt4-svg which should be part of "default qt" but I can't pin down which package I need to make this work.

I have the same problem with it in the stage 4 tarball. I moved the binaries to /usr/local/bin so they can be launched from any dir in a terminal and from the main menu and launcher bar. Opening a terminal and running /usr/local/bin/Cadence "fixes" this.

I just noticed that I have to do this every time I turn on my DAW. I'll keep this on my to-do list and hopefully have a permanent solution at some point.

Let me know if using the full path to the executable doesn't help.

Looks like a missing qt lib. Do you have dev-python/PyQt4 installed? If so, which version?

I have dev-python/PyQt4-4.11.1-r1000

Code:
[~]$ Cadence

unzipsfx:  cannot find myself! [Cadence]
sh: line 0: cd: /tmp/cadence: No such file or directory
sh: ./cadence: No such file or directory


It must have created the directory anyway because it was there when I checked, the message didn't come up the following time I tried:

OK. I have PyQt4-4.10.3-r2. If you're willing to try this, see if downgrading helps and let me know whether it does.

I'm really hoping you can keep the kernel seeds going/mirroring upstream. Other than that, I don't really care; though it'd be cool to automate using genkernel with the seed. Hmm I'd prefer just using the seed and automating the kernel make oldconfig && make && make modules install cycle, perhaps with make nconfig in there after oldconfig for interactive installs.)

Personally I wish kernel-seeds were still Pappy's baby, too; but it could make a nice focus for collaboration with funtoo.

Kernel seeds aren't still Pappy's baby? I think I missed something there.

I migrated my server recently. I need to restore my kernel seeds mirror. I noticed that the latest seed is 3.9. I'm going to go look for Pappy.

EDIT: OK, I guess Pappy sold the site. I hope the new owner keeps it going!

Heh nice one, audiodef; the school section is cool. Reminds me of stuff I used to do.

Keep up the good work. :)

I hate to say this, but I'm about to go on a family visit, so I'll be unable to look into this for a week and a half. I'll try to remember to check it out, though!

This line
Code:
ImportError: /tmp/cadence/PyQt4.QtGui.so: undefined symbol: _ZNK7QWidget14accessibleNameEv
means the bundled PyQt4.QtGui.so can't find a specific Qt symbol, in this case:
Code:
$ c++filt  _ZNK7QWidget14accessibleNameEv
QWidget::accessibleName() const

So find out where that's meant to come from: it may have been removed in the version of whatever lib.
Code:
ldd /tmp/cadence/PyQt4.QtGui.so
will tell you what the shared object links to, so you can chase the list down.

If it is version-specific (seems a bit unlikely from the name, but who knows), you could try installing the exact same versions (with emerge, perhaps in a ROOT), and then moving them in place; perhaps by rebuilding the zip if this is done as part of install, or in the ebuild, which would have an = dep on the relevant packages. The latter is cleaner, but then there's not much point in an ebuild that ties the user to a specific version of a system library, so really just documenting how to rebuild the zip would be a Good Enough Thing(TM).

In passing this is why bundled system libs are a pita; it's not the lib it needs so much, it's the fact that they've been linked to specific version of other libs, and that freezes everything. In any event, make sure you keep it confined to its own dir under /opt.

Gentoo Studio looks like it's just what I've been looking for for months! Just curious though, is anyone aware of a similar guide for Arch? As only an intermediate user, I'd probably have an easier time with that distro if only there were a comprehensive step-by-step tutorial like audiodef's.

Also, the kernel seed links in the manual installation and front page should be updated to kernel-seeds.org instead of kernel-seeds.gentoostudio.org.

Arc

I'm glad you find it useful!

I haven't heard of a guide for Arch, but I'm sure the manual install guide for GS is transferrable to other distros.

I updated the kernel seeds link recently, after hearing from Pappy that the site now belongs to a Gentoo bigwig (maybe they'll be integrated into gentoo-sources, which would rock).

Ah go on: tell us what's so nice about one of those then, as you've obviously just bought one ;-)

Why did you buy it, and what does it enable you to do, that you couldn't do before?

I took advantage of a half-off sale. The XT-BC is a bass character plugin. It has two controls: body and clarity. Each of those controls has a Q value. The plugin has some kind of tracking algorithm that follows the frequency of the audio track so your settings sound natural as the audio frequency changes. The XT-VC in the same plugin bundle is for vocals and works in a similar fashion. I've tried both and they both sound very nice. They're now part of my indispensible favorites in my Ardour "favorites" plugins.

Has anyone managed to get pure data installed? I know there is an overlay for it but the install fails for me.

Also, audiodef (or anyone else?) could you take a look at the radium ebuild if you get a chance? The one in the pro-audio overlay and on the gentoostudio website is very old now and, from looking at the changelogs, dates back to before before Pd was added to it. I was going to create my own updated ebuild but then I realized it seems like more of a job than just changing the version number. Also I have no idea if it needs the qt stuff in that old ebuild or not, qt3 support still needed?
