Audio-recorder doesn't run under Quantal Ubuntu distribution

[Xavier Farret]

I've just upgrade audio-recorder to 0.9.7 on quantal distrib and i've got trouble to launch it :
Error: Cannot find settings for /apps/audio-recorder/ in GNOME's
registry. Please run "make install" as sudo or root user.

I try on a fresh quantal install, the trouble is the same. All installation are on 64bits.

This bug has been fixed in version 0.9.8.
Audio-recorder failed to find configuration settings in DConf and exited (in version 0.9.7 of audio-recorder).
Some facts:
1) The /apps/audio-recorder/ schema was visible in dconf-editor.
$ dconf-editor

2) Dump of /apps/ did not returned anything for a.r when this bug was present.
$ dconf dump /apps/

3) The schema (template) was correctly installed to /usr/share/glib-2.0/schemas/
$ ls -l /usr/share/glib-2.0/schemas/*audio*
-rw-r--r-- 1 root root 4897 Nov 4 21:43 /usr/share/glib-2.0/schemas/org.gnome.audio-recorder.gschema.xml

4) Gsettings list-schemas correctly reported all keys.
$ gsettings list-schemas | grep -i audio
  org.gnome.audio-recorder
  org.gnome.audio-recorder.track
  org.gnome.audio-recorder.skype
  org.gnome.audio-recorder.players

5) The user's private values for /apps/audio-recorder/ are saved to "$HOME/.config/dconf/user" file. It's a binary file. This file had no entries for a.r because it was never started in the actual Ubuntu-machine (with this bug).
$ ls -l $HOME/.config/dconf/user

The error was located in src/dconf.c, function conf_get_base_settings() where g_settings_schema_source_lookup() failed to find config schema for /apps/audio-recorder/. This schema is configured by data/org.gnome.audio-recorder.gschema.xml that is compiled and installed to the system.

This error was fixed by calling g_settings_schema_source_lookup() and setting its last parameter to TRUE. (recursive=TRUE).
GSettingsSchema *schema = g_settings_schema_source_lookup(source, APPLICATION_SETTINGS_SCHEMA, TRUE);

Now the program correctly finds the /apps/audio-recorder/ in Gsettings (with DConf backend). User's private values (values != default) are saved to $HOME/.config/dconf/user. And all is good.

Thanks to Yéna for making several tests to fix this bug.

I am getting this same error message ("Cannot find settings for /apps/audio-recorder/ in GNOME's registry. Please run "make install" as sudo or root user.") when trying to start audio-recorder, but I used version 0.9.8 to compile the program. Also, I am not using Ubuntu, I am using Arch.

I did a bit of poking around and the schema was visible in dconf-editor. However if I run "gsettings list-schemas | grep -i audio" I get nothing back.

Here is the PKBUILD I used to create my audio-recorder package:

Hello Mark,

1a) Please check if you find the "org.gnome.audio-recorder.gschema.xml".
$ ls -l /usr/share/glib-2.0/schemas/*audio*

I think you already have put the file in /usr/share/glib-2.0/schemas/.

1b) Then re-compile all XML schemas (do as root or sudo). Have you done this? Run:

glib-compile-schemas /usr/share/glib-2.0/schemas/
-----

2) The original code of conf_get_base_settings() in src/dconf.c was this. Can you temporarily replace the function with this code. I modified this function to be able to detect if user has compiled and installed the GSettings-schema file correctly. This older version simply seq-faults if the "settings" object is NULL. Test the code from a terminal window.

GSettings *conf_get_base_settings() {
    // Return GSettings (base) object. This points to /apps/audio-recorder/.

    GSettings *settings = g_settings_new(APPLICATION_SETTINGS_SCHEMA);

    if (!G_IS_SETTINGS(settings)) {
         LOG_ERROR("Cannot find settings for %s\n", APPLICATION_SETTINGS_SCHEMA);
         return NULL;
    }
    return settings;
}
--------

3) Does Arch-Linux use DConf as its Gsettings backend? It propably does. I am not sure how to check this.
Does Arch run GNOME or KDE?

Kindly report your findings.

Thanks for the help

I changed the code of "dconf.c" as you indicated in post 3 [ https://bugs.launchpad.net/audio-recorder/+bug/1074928/comments/3 ] and compiled the package again. That seems to have fixed this issue with audio-recorder failing to start.

I'll leave a note over on Arch User Repository pointing people to this thread.

BTW- Arch can be installed to run about any desktop environment, but I am using Gnome 3/Gnome-Shell

thanks again.

Hello,
Very good Mark.
I will consider rollback to the original code (or find a better solution) so it works in all distros.

Would you please send me the Arch-spesific files for compilation and packaging so I can add then to the source-tree on Launchpad.net. My email: osmoma at gmail punto com

I will add a new directory called "Arch-Linux". Is this name OK?
http://bazaar.launchpad.net/~osmoma/audio-recorder/trunk/ <-- Arch-Linux

BTW: I am preparing a new version for Ubuntu 13.04 (april 2013). Eg. the hard-coded values in src/media-profiles.c can now be removed because GNOME-media has (propably) added new values for Gstreamer 1.0.
Ref: http://bazaar.launchpad.net/~osmoma/audio-recorder/trunk/view/head:/src/media-profiles.c

Sure.

All we really have for audio-recorder in Arch is just a simple script for building the package which I will link to below:

https://aur.archlinux.org/packages/au/audio-recorder/PKGBUILD

Here are direct links for downloading the specified dependencies from the Arch repositories:
hicolor-icon-theme https://www.archlinux.org/packages/extra/any/hicolor-icon-theme/download/
dconf https://www.archlinux.org/packages/extra/i686/dconf/download/
libgnome-media-profiles https://www.archlinux.org/packages/extra/i686/libgnome-media-profiles/download/
gstreamer0.10-good-plugins https://www.archlinux.org/packages/extra/i686/gstreamer0.10-good-plugins/download/
gstreamer0.10-ugly-plugins
gstreamer0.10-bad-plugins

[mark (emailthistomark)]

Missed two:

gstreamer0.10-ugly-plugins https://www.archlinux.org/packages/extra/i686/gstreamer0.10-ugly-plugins/download/
gstreamer0.10-bad-plugins https://www.archlinux.org/packages/extra/i686/gstreamer0.10-bad-plugins/download/

Let me know if that was not what you need. I would be happy to help out.
