Description Don Scorgie 2006-03-23 05:58:01 UTC 
I feel like I'm doing something stupid, but can't see what it is.  Apologies if
it is stupid.

When compiling a simple test program (which I'll attach in a minute) using g++,
a whole slew of errors are the result:

/opt/gnome2/include/dbus-1.0/dbus/dbus-glib-bindings.h: In function ‘void
org_freedesktop_DBus_Introspectable_introspect_async_callback(DBusGProxy*,
DBusGProxyCall*, void*)’:
/opt/gnome2/include/dbus-1.0/dbus/dbus-glib-bindings.h:28: error: invalid
conversion from ‘void*’ to ‘DBusGAsyncData*’
/opt/gnome2/include/dbus-1.0/dbus/dbus-glib-bindings.h: In function ‘void
org_freedesktop_DBus_request_name_async_callback(DBusGProxy*, DBusGProxyCall*,
void*)’:
/opt/gnome2/include/dbus-1.0/dbus/dbus-glib-bindings.h:71: error: invalid
conversion from ‘void*’ to ‘DBusGAsyncData*’
/opt/gnome2/include/dbus-1.0/dbus/dbus-glib-bindings.h: In function ‘void
org_freedesktop_DBus_release_name_async_callback(DBusGProxy*, DBusGProxyCall*,
void*)’
...
This continues for a 15 errors.  The same program as a C program works as expected.

A simple program that demonstrates the problem

Save file as silly.cpp
compile with
g++ -o silly silly.cpp `pkg-config --cflags --libs dbus-glib-1`
Watch errors appear

Rename silly.cpp to silly.c and  recompile with:
gcc-o silly silly.c `pkg-config --cflags --libs dbus-glib-1`
watch it compile cleanly.

fix

This fixes dbus-binding-tool to generate C++ compatible bindings.
