[dbus-cplusplus-devel] dbusxx-xml2cpp bug (gitorious branch)

[David K. <zu...@li...>]

Hi,

I grabbed dbus-c++ from the gitorious branch and started playing with the 
examples. I actually stopped right at the simplest example - 
examples/echo.

Invoking the Hello method as mentioned in README results in an empty 
string. When I looked into the issue, it seems to be a bug in the server 
glue (generated by dbusxx-xml2cpp), specifically, the marshaller:

     ::DBus::Message _Hello_stub(const ::DBus::CallMessage &call)
     {
         ::DBus::MessageIter ri = call.reader();

         std::string argin1;
         ri >> argin1;
         std::string argout1;
         Hello(argin1);
         ::DBus::ReturnMessage reply(call);
         ::DBus::MessageIter wi = reply.writer();
         wi << argout1;
         return reply;
     }

changing the Hello() invocation into "argout1 = Hello(argin1)" fixes the 
issue.

Looking at the stub (and at the generator), this is a general problem. 
Being all new to this... I see where in generator is this code output, but 
I don't really know how to fix this.

Best regards,
