Anyone out there using ambix on Linux?
I'm seeing various instabilities, for example trying out the converter
standalone I get a segfault when connecting output ports, and it looks
like the Jack JUCE component is doing some unaligned memory copies.
Any hint on how to fix this?
I get Ardour crashes if I try to use the converter LV2 plugin as well.
See below for a trace of the standalone binary...
Thanks for any help!

I have compiled the git-version and tested with the converter standalone.
The attached patch should fix this problem.

That seems to have fixed that problem. But I'm still having other
problems :-(
On a different machine I see this problem when I try to bring up the LV2
GUI for the encoder plugin in, say, ardour3:
[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has
not been called
[xcb] Aborting, sorry about that.
xcb_io.c: 179: dequeue_pending_request: Assertion

And then ardour3 crashes.

definitely caused by use of X / GUI toolkit calls from the wrong thread.
Not legal.

Ok, thanks, staring at code - no idea what to look for (Ambix uses the
JUCE LV2 wrapper) ...
On my laptop (Fedora 21 instead of Fedora 20, different video chipset)
the GUI starts fine but it can randomly crash with the same message.
Race condition that is sometimes triggered?
Anyone our there running the Ambix LV2 plugins successfully? (in, for
example, Ardour3?)

Not sure if this works, but can Ardour be built with native linux VST
support and ambix built as a native linux VST?
Cheers,

Hi Fernando and list,
thanks for the bugfix of the converter I will look into that.
As you probably already found out the Linux version is not very stable yet.
Part of it is probably in my code, but also in the JUCE framework which
I think needs more care. As more people are working on JUCE now there
might be ressources to look into the JUCE related problems. (If somebody
is at Musikmesse Frankfurt you could walk over to the guys at ROLI and
give them a wishlist.)
However I currently don't have the time to improve the software under
Linux, I make sure it works for OSX and Windows.
Especially the encoder GUI does make trouble with the OpenGL drawing.
Therefore if somebody wants to invest some time to improve things for
Linux you are very much welcome, I will support it as much as I can.
Best, Matthias
