Topic: lv2 plugin problem in linux

There seems to be a problem with the lv2 manifest.ttl file in recent Pianoteq versions.    When I start the Ardour DAW I see this message in the terminal:

lilv_world_load_file(): error: Error loading file `file:///usr/lib/lv2/Pianoteq 5.lv2/manifest.ttl'
lilv_world_load_bundle(): error: Error reading file:///usr/lib/lv2/Pianoteq 5.lv2/manifest.ttl

This file exists and is readable so I think there is either a format problem in the file, possibly due to lilv version issue.  I have seen this problem in 2 systems, kxstudio 14.04 using lilv 0.16, and AVLinux 6.0.4 using lilv 0.20 (latest version).   The problem is not specific to Ardour.   Qtractor and carla cannot use the Pianoteq lv2 either.

Because of this problem the lv2 plugin does not work.

Re: lv2 plugin problem in linux

Apparently it does not like anymore to have whitespaces in the plugin name.

If you edit the manifest.ttl file to replace 'Pianoteq 5.so' by 'Pianoteq_5.so' and 'Pianoteq 5.ttl' with 'Pianoteq_5.ttl' , and rename the corresponding files accordingly , the plugin works again.

Re: lv2 plugin problem in linux

Thanks for the information.   I also changed the name of Pianoteq 5 (5 channels).ttl to remove the spaces and that works too.
