gupnp-binding-tool

[Michael Rumpf <michael rumpf gmail com>]

Hi,

I'm very new to gupnp and I might still have some issues understanding the concepts behind it. Here is what I'm trying to do. I use the gupnp-binding-tool in order to generate the server side stub code for 3 service description.xml files.

1. when I #include all the 3 generated files in my code (each one generated with a different prefix) I get a linker error that the function _free_cb_data() has been defined 3 times.

I see 3 possible solutions:

a) Use the --prefix also for the function  _free_cb_data() 

b) Move the function  _free_cb_data() into the gupnp library

c) Use a #ifndef #define #endif sequence in order to define the method only once

Currently I help myself with the following script

../../base/bin/gupnp-binding-tool --prefix renderingcontrol --mode server RenderingControl/description.xml > audio-renderer-renderingcontrol.c1

cat audio-renderer-renderingcontrol.c1 | sed -e 's/_free_cb_data/_renderingcontrol_free_cb_data/g' > audio-renderer-renderingcontrol.c

rm audio-renderer-renderingcontrol.c1

2. The generated code contains methods for connecting the action callback handlers and for the state variable handlers. But the code does not provide a method where all action callback and state variable handlers get connected. I still need to add calls like this

<PREFIX>_<ACTIONNAME>_action_connect(GUPNP_SERVICE (myServiceInfo), G_CALLBACK(<PREFIX>_<ACTIONNAME>_action_set), NULL);

<PREFIX>_<ACTIONNAME>_action_connect(GUPNP_SERVICE (myServiceInfo), G_CALLBACK(<PREFIX>_<ACTIONNAME>_action_get), NULL);

It would be no problem for the gupnp-binding-tool to generate one function like this

action_connect_all (GUPnPService *service)

This would be a dummy implementation where no individual userdata can be passed to the different action_connect functions, but it would save a lot of typing/scripting in order to get a service up and running.
