lv2 plugin not found in ardour / qtractor + jalv error

[ko-phy]

I'm trying to install Fabla. "make" and "make install" run just fine, but then I cannot find the plugin in either ardour or qtractor. Furthermore, running run.sh with jalv installed leads to the following error:

Error opening file /home/stefanos/.lv2/fabla.so/manifest.ttl (Not a directory) lilv_world_load_bundle(): error: Error reading file:///home/stefanos/.lv2/fabla.so/manifest.ttl Error opening file /home/stefanos/.lv2/fabla_ui.so/manifest.ttl (Not a directory) lilv_world_load_bundle(): error: Error reading file:///home/stefanos/.lv2/fabla_ui.so/manifest.ttl Error opening file /home/stefanos/.lv2/fabla.ttl/manifest.ttl (Not a directory) lilv_world_load_bundle(): error: Error reading file:///home/stefanos/.lv2/fabla.ttl/manifest.ttl Error opening file /home/stefanos/.lv2/manifest.ttl/manifest.ttl (Not a directory) lilv_world_load_bundle(): error: Error reading file:///home/stefanos/.lv2/manifest.ttl/manifest.ttl Plugin: http://www.openavproductions.com/fabla Failed to find plugin http://www.openavproductions.com/fabla.

Any suggestions on what to do?

Hi @delete000,

Running '''lv2ls''' lists all LV2 plugins installed on the system: this should list Fabla.

There's certainly an error: check the file paths: '''/home/stefanos/.lv2/fabla.so/manifest.ttl''' that /fabla.so/ is not correct.

Please remove all fabla related folders in ~/.lv2/ and then do a make install from fresh (without existing files there).

Hope that works, please report back :) Cheers, -Harry

I think I found what was wrong: the installer copies the preset folders into ~/.lv2, but does not copy fabla.so and fabla_ui.so into the folders. Doing this manually fixes the problem. I can now use fabla in ardour. Unfortunately, my qtractor crashes frequently with plugins and zynjacku doesn't even launch (see https://bugs.launchpad.net/ubuntu/+source/zynjacku/+bug/1185815). Using the provided run.sh leads to error & segfault:

stefanos@lappy:~/Downloads/samplers/openAV-Fabla-master$ ./run.sh Plugin: http://www.openavproductions.com/fabla UI: http://www.openavproductions.com/fabla/gui JACK Name: Fabla

./run.sh: line 3: 5237 Segmentation fault (core dumped) jalv.gtk http://www.openavproductions.com/fabla

For now I can make do with ardour as a host, but ultimately it would be nice to be able to use fabla as standalone. Thanks for the help :-)

EDIT :: sorry, was using old version of jalv, updated to the current one and everything works like a charm.

Hey,

Please report QTractor crashes to Rui: www.sourceforge.net/p/qtractor/tickets/ ZynJackU is not maintained, and a dead project: please don't use it (see http://nedko.arnaudov.name/ )

Ah glad Jalv is working fine there: I use Jalv to test the plugins here, so it should work 100%. Cheers, I'll mark this bug as closed: I checked the '''makefile''', and it installs the files properly. -Harry
