librdf fatal - Cannot add statement to model

vz1 · February 23, 2009, 12:02pm

Hi all,

I’ve an issue. I haven’t errors when ardour compiling.

I get the following when I start Ardour:

Loading ui configuration file /etc/ardour2/ardour2_ui_dark.rc
theme_init() called from internal clearlooks engine
ardour: [INFO]: Ardour will be limited to 8192 open files
loading system configuration file /etc/ardour2/ardour_system.rc
loading user configuration file /home/studio/.ardour2/ardour.rc
ardour: [INFO]: Using SSE optimized routines
librdf fatal - Cannot add statement to model
librdf fatal - Cannot add statement to model
ardour: [INFO]: looking for control protocols in /home/studio/.ardour2/surfaces/:/usr/lib/ardour2/surfaces/

ardour: [INFO]: Control surface protocol discovered: “Mackie”
powermate: Opening of powermate failed - Aucun fichier ou rÃ©pertoire de ce type
ardour: [INFO]: Control protocol powermate not usable
ardour: [INFO]: Control protocol Tranzport not usable

What’s wrong with librdf?

I’m running under gentoo/proaudio overlay.

Here, the dependencies I use for ardour-2.7.1:

liblo-0.24
aubio-0.3.2-r1
liblrdf-0.4.0
raptor-1.4.17

Thanks for your help.

Yes, this is harmless. It’s properly fixed in redland svn already and will be included in the next release (Note you probably don’t want to try upgrading to svn redland at this time though).

I’m getting really tired of hearing about it so maybe I’ll look into what’s holding back that release. Later. Maybe.

The answer from irc:

14:37 vz what means: “librdf fatal - Cannot add statement to model” when ardour starts
14:37 hollunder_ vz, known bug, nothing serious, afaik
14:38 hollunder_ librdf bug
14:38 vz Ok.
14:38 vz So I can forget this?
14:38 peppo vz, yes. your messages appear twice for some reason.
14:39 vz Exact. Thanks.
14:39 cannam should check that rdf error with drobilla, I think it’s his trees storage module returning a fatal error for the case where the statement is already in the module (e.g. because two sources contain the same statement) - which is not considered an error for the other storage modules
14:39 cannam …no doubt he knows, though
14:40 cannam (I meant “statement is already in the model”)
14:40 hollunder_ I heard it’s fixed, just not yet released
14:40 cannam right-o then
14:40 cannam it’s benign, anyway (and also only a one-liner to fix I think)
