What is required to run GMainLoop inside GThread with Dbus functionality.

[Mukesh Savaliya]

Hello, please reply to this, I am helpless.

   I am suspecting on GThread functionality and its dependency on other
libraries. As, I have tried all the way, but still its not working. The same
thing is working on PC very well. This means PC library has all the requires
files, where as something is missing on ARM board.

 Can anybody provide me the dependency files required for running GMainLoop
and GThread with Dbus?

Dear, Alban Crequy,

I have used strace ,and observed that DBusGProxy *Proxy =0. And error
message shows "Connection is closed". 

But,I am wondering why this is happening only on ARM board. It gets
DbusGConnection connection=(int)xyz. But proxy is 0. And this happens only
when I use g_main_loop_run(mainloop),inside a thread.

What is missing than?

Thanks for replying.

Can you use strace on the thread which is supposed to receive the
D-Bus signal? You will know whether or not your thread receives the
D-Bus signal on the socket.

1. If it is received, dbus_g_proxy_connect_signal is not done correctly.
  Is there any error on stderr or syslog?

2. If it is not received:

  2.1. Is your thread blocked on select() or poll()? You can check if
  the file descriptor for D-Bus is correctly specified in select/poll.

  2.2. You can also check with dbus-monitor whether the D-Bus method
  call "AddMatch" is done correctly on the right object with the right
  match rule when you create the proxy and when you connect to the D-Bus
  signal.

BR,
Alban
