Problems binding a struct that's not a GObject

[Emmanuel Rodriguez <emmanuel rodriguez gmail com>]

Hi,

I'm writing the bindings for libunique (http://live.gnome.org/LibUnique) so far everything works fine except for the marshaling of the struct "UniqueMessageData". This type is a normal struct and not a GObject documented as follows:
 typedef struct _UniqueMessageData UniqueMessageData;


I added a typemap file to the project with the following lines:
 TYPEMAP
 
 UniqueMessageData* T_GPERL_GENERIC_WRAPPER
 UniqueMessageData_ornull* T_GPERL_GENERIC_WRAPPER

And created newSVUniqueMessageData() and SvUniqueMessageData() in the corresponding XS file. The idea is to convert the struct into a perl hash and vice-versa.

So far the XS module compiles and can be loaded, but when I run the example application (from 2 different shells):

shell1$ perl -Mblib examples/sample.pl "Hello world"
shell2$ perl -Mblib examples/sample.pl "It works"

I get in the first shell:
GType UniqueMessageData (138666312) is not registered with gperl at examples/sample.pl line 40.

This bug only happens if I connect the signal 'message-received' and if the main application receives a message. If the signal handler is not connected and a message is sent there will be no crash. This leads me to suppose that the marshaling of the struct UniqueMessageData to a Perl hash ref is not done properly. I seem to know what's the issue but I don't know how to fix it.

The module is hosted here:Â http://github.com/potyl/gtk2-unique/tree/master
