Hi all,
I'm adding gobject-introspection support to my library. It's working
well for the GObject classes, but I just can't get it to work for
GBoxed objects. I'm sure I'm missing something obvious. Do I need to
write an override to make a class for the type myself?
I've spent some time googling and grepping around and not found a
simple example. Again, I'm probably being stupid.
I'm doing something like this in a header:
/**
* VIPS_TYPE_BLOB:
*
* The %GType for a #VipsBlob.
*/
#define VIPS_TYPE_BLOB (vips_blob_get_type())
GType vips_blob_get_type( void );
typedef ... VipsBlob;
VipsBlob *vips_blob_new( int n );
and this in the .c file:
GType
vips_blob_get_type( void )
{
static GType type = 0;
if( !type )
type = g_boxed_type_register_static( "VipsBlob",
(GBoxedCopyFunc) ...,
(GBoxedFreeFunc) ... );
return( type );
}
/**
* vips_blob_new:
* @n:
*
* Returns: (transfer full): the new #VipsBlob.
*/
VipsBlob *
vips_blob_new( int n )
{
return (...a new VipsBlob);
}
Now when I start up Python I get this:
>>> from gi.repository import Vips
>>> Vips.blob_new
<function blob_new at 0x7ffff7e31de8>
>>> Vips.blob_new(12)
Program received signal SIGSEGV, Segmentation fault.

This is on current Ubuntu, so:
$ pkg-config gobject-introspection-1.0 --modversion
1.30.0
