Runtime Error on 32bits...
-
I'm getting this error on rutime:
@
(InoveSATBEV:7109): GConf-WARNING **: Client failed to connect to the D-BUS daemon:
Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
GConf Error: No D-BUS daemon running(InoveSATBEV:7109): GConf-WARNING **: Client failed to connect to the D-BUS daemon:
Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.** (InoveSATBEV:7109): WARNING **: gst_gconf_get_string: error: No D-BUS daemon running
@The application don't close, still running, but some events install on the QWebView is not executed:
Appears to be a something with Webkit... I'm not sure!The code that insert Qwebview events:
@
ui->webView->page()->mainFrame()->addToJavaScriptWindowObject("sender", this);
@The JavaScript inside the SVG File loaded in "webview":
@
sender.clicked( 1 );
@On 64bits, works everything fine.
What's the problem? -
This prolem occours when I run with Root!
If I use the sudo ./MyApplication, this error appears to me:
@
WARNING: Phonon needs QCoreApplication::applicationName to be set to export audio output names through the DBUS interface
@I don't use any kind od "audio"... not in my code!
-
the "documentation":http://qt-project.org/doc/qt-4.8/qcoreapplication.html#applicationName-prop is your friend, use it.

KA510... I don't change anything between Compilations...
The problems is all showed above, the errors still the same!I change the main.cpp, now is:
@
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
a.setApplicationName( "Balança Embarcada Veicular - Sistema Assistência Técnica" );
a.setApplicationVersion( "1.0" );
a.setOrganizationDomain( "none" );
a.setOrganizationName( "Inove Tecnologia" );
setlocale( QApplication::UnicodeUTF8, "C" );
MainWindow w;
w.show();
return a.exec();
}

QApplication::setOrganizationName( orgName );
QApplication::setOrganizationDomain( orgDomain );
QCoreApplication::setApplicationName( appName );
QCoreApplication::setApplicationVersion( appVersion );
QCoreApplication::setOrganizationDomain( orgDomain );
QCoreApplication::setOrganizationName( orgName );
QApplication a(argc, argv);
a.setApplicationName( appName );

@Still got problems...
This problems could be from lib's?
The 64bits I using OpenSuse to Compile, And 32bits I'm using Ubuntu 32bits (VMware)! -
Well, I install OpenSuse 32bits (with KDE)
Install QT, Compile on then and run...
The errors appears, but the application works as needed:@
klauncher(26995) kdemain: No DBUS session-bus found. Check if you have started the DBUS server.
kdeinit4: Communication error with launcher. Exiting!
Balança Embarcada Veicular - Sistema Assistência Técnica(26948): No ksycoca4 database available!Balança Embarcada Veicular - Sistema Assistência Técnica(26948)/kdecore (trader) KServiceTypeTrader::defaultOffers: KServiceTypeTrader: serviceType "PhononBackend" not found
@Appears to be something with Ubuntu or maybe the gnome 32bits.
