Ich habe Qt mit integriertem dbus für Windows neu kompiliert.QtService-Anwendung kann keine Verbindung zum Systembus herstellen, wenn sie als Dienst ausgeführt wird
Ferner ich eine QtService Anwendung implementiert haben, die einen Dienst und ein Objekt auf dem Systembus Register wie folgt:
QDBusConnection::systemBus().registerService("com.mycompany.Configuration");
QDBusConnection::systemBus().registerObject("/com/mycompany/Configuration/MySetting", myObject);
Nun, wenn ich die Dienstanwendung leite mit dem -e Parameter (läuft als regelmäßige Anwendung) es funktioniert gut und sowohl dbus-monitor als auch qdbus --system zeigen Sie mir den registrierten Service und Objekt.
Wenn ich jedoch die Anwendung als Windows-Dienst ausführt, registriert es nichts am Systembus.
den Dienst Debuggen gibt mir die Fehlermeldung
verbunden Nicht zu D-Bus-Server
wenn registerService(...) und registerObject(...) aufrufen.
ich die Umgebungsvariablen gesetzt haben:
DBUS_SYSTEM_BUS_ADDRESS = autolaunch:
DBUS_SYSTEM_BUS_DEFAULT_ADDRESS = autolaunch:
Meine system.conf Datei:
<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-Bus Bus Configuration 1.0//EN"

Zusätzlich habe ich eine com.mycompany.Configuration.conf Datei im Ordner system.d:
<!DOCTYPE busconfig PUBLIC
"-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN"

<allow receive_sender="com.mycompany.Configuration"/>
</policy>
</busconfig>
Der Windows-Dienst selbst heißt com.mycompany.Configuration und wird als Local Syst ausgeführt EM-Konto.
Außerdem dbus ausführliche Ausgabe zeigt, dass etwas auf, wenn mein Windows-Dienst wird gestartet wird:

Ich weiß wirklich nicht, was das Problem sein könnte und jede mögliche Hilfe schätzen würde.
Edit: Dies scheint das gleiche Problem zu haben: http://comments.gmane.org/gmane.comp.freedesktop.dbus/14895
