Hi, It seems it depends on which version of dbus you are using. If you are using very old version like 0.23 then these symbols are not there. But if you are using new version 0.61 onward then it should be ok. In my system I have both 0.23 version and 1.0.2 version. I am unable to find these symbols in old version but in new version I do find these and in fact I uses them also. So if you have newer version then it should be ok. -Br Naveen <div>On 10/30/07, Aashish Raina <<a href="mailto:aashish_raina@persistent.co.in">aashish_raina@persistent.co.in</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi all           dbus_connection_read_write()          dbus_message_iter_get_basic()          I am using            libdbus-1.so   These 2 api say undefined refrence to it ,do i need to have some different .so file.If so do i need to update   D-Bus 1.0.2. please share this information. thanks in advance aashish DISCLAIMER ========== This e-mail may contain privileged and confidential information which is the property of Persistent Systems Ltd.
