Using Vamp Plugins and Hosts > Host Forum: Sonic Visualiser

"Segmentation fault" on Ubuntu 10.04 ?

(1/1)

jean-louis:
Hi everyone !

I have been developing a plug-in, lately, for sonic-visualiser (SV). I tested it with SV, under Ubuntu 10.04, using a command line like the following:

--- Code: ---VAMP_PATH=. sonic-visualiser
--- End code ---

When I try to load a file with the option in the menu (or equivalently with the button on the menubar), SV crashes with a "Segmentation fault" error message. I can however load a file by drag-n-dropping it over the window. I can then run my plug-in, which seems, on my few tests, to work without errors. When I try to open the plug-in dialog before the file is entirely loaded (I'm the impatient type of person), it again crashes with a segfault.

The weird thing is that, since it crashes even before I tell him to load the plug-in (and even when the plug-in is nowhere for SV to be found), I tried to launch it the "normal" way, from the ubuntu menu. It then seems to work OK.

If I run it from the terminal, though, I get the same behaviour. Here is the output I get:

--- Code: ---$ sonic-visualiser

Finished setting up OSC interface
Comparing current version "1.7.2" with latest version "1.7.1"
Segmentation fault

--- End code ---
The last line only appears when I try to open the "open file" dialog. On this log, the plug-ins were not found, because I removed them from the ~/vamp folder (I guess).

Well, I m not sure what exactly goes wrong there... Could the plug-ins I used (especially the one I develop) have "broken" my current installation of SV? Or is this something related to a build problem within SV?

Best regards,

Jean-Louis

added 1/12/2010: I ran the plugin-tester with the following command line:

--- Code: ---$ VAMP_PATH=. ~/PATH/TO/vamp-plugin-tester -a

--- End code ---
and obtained:

--- Code: ---... <a lot of debugging "printf" stuff > ...
vamp-plugin-tester: All tests succeeded for this plugin

vamp-plugin-tester: All tests succeeded
Segmentation fault

--- End code ---
What should I think of that?...
