[Linphone-users] minimum gtk requirement

[Liviu Andronic]

Dear all
What is teh minimum GTK requirement for 3.5.0? The README in the sources  
suggests:
        + if you want to gtk/glade interface:
                - gtk>=2.16.0

However, various config files seem to require several more recent version  
of GTK.
$ fgrep requires gtk/*.ui
gtk/about.ui:  <!-- interface-requires gtk+ 2.12 -->
gtk/buddylookup.ui:  <!-- interface-requires gtk+ 2.16 -->
gtk/call_logs.ui:  <requires lib="gtk+" version="2.16"/>
 gtk/chatroom.ui:  <!-- interface-requires gtk+ 2.12 -->
gtk/contact.ui:  <requires lib="gtk+" version="2.16"/>
gtk/log.ui:  <requires lib="gtk+" version="2.16"/>
 gtk/main.ui:  <requires lib="gtk+" version="2.22"/>
gtk/parameters.ui:  <requires lib="gtk+" version="2.22"/>
gtk/password.ui:  <!-- interface-requires gtk+ 2.16 -->
 gtk/sip_account.ui:  <!-- interface-requires gtk+ 2.6 -->
gtk/tunnel_config.ui:  <requires lib="gtk+" version="2.18"/>


The reason I ask is that requiring GTK 2.22 (for main.ui and  
parameters.ui) renders Linphone 3.5.0 incompatible with Ubuntu Lucid LTS,  
which ships GTK 2.20. In default configuration, I get the following error  
at start-up:
address@hidden:~$ linphone

 ** ERROR **: Couldn't load builder file: /usr/share/linphone/main.ui:
 required gtk+ version 2.22, current version is 2.20
 aborting...
 Aborted

If I comment out the relevant line in main.ui and parameters.ui, then  
3.5.0 starts and seems to behave just fine. Since we're publishing the  
Lucid package on the Linphone PPA [1], I wanted to make sure that this is  
safe. Just in case, I report these messages that I get on the console:
address@hidden:~$ linphone
 ALSA lib conf.c:4630:(snd_config_expand) Unknown parameters 0
 ALSA lib control.c:882:(snd_ctl_open_noupdate) Invalid CTL default:0

 (linphone:7802): Gtk-WARNING **: gtk_window_set_wmclass: shouldn't set
 wmclass after window is realized!


 (linphone:7802): GLib-GObject-WARNING **: IA__g_object_notify: object
 class `GtkStatusIcon' has no property named `name'

 (linphone:7802): Gtk-WARNING **: Could not load image 'linphone2.png':
 Failed to open file '/usr/share/linphone/linphone2.png': No such file
 or directory

 (linphone:7802): Gtk-WARNING **: Could not find signal handler
 'linphone_gtk_create_fonics_account'


Please let me know if the above hack (removing requirement for GTK 2.22 in  
main.ui and parameters.ui) is acceptable for most cases. Regards
Liviu
