Problems with LV2 plugins - Linux-audio-user

26 Jun 2008

Hi,
I'm trying to have LV2 plugins and hosts work but I'm having problems.
The involved packags (compiled from tarballs) : 
- slv2-0.4.5 (because latest 0.5.0 caused zynjacku host to not compile)
- ll-plugins-0.2.0
- lash-0.5.4
- lv2core-2.0
- zyn-1
- zynjacku-1
- lv2dynparam1-1

Running in a Ubuntu 08.04 Linux 2.6.24-19

The problem is that I can't load any ll-plugin with any host (zynjacku
or lv2_jack_host), while zyn-1 does work (only in zynjacku since it
needs specific extensions)

I believe that the clue to the problem is shown in lv2_inspect result
below. Any idea??
