Currently, MySQL is the only supported database.

Therefore I had a look into gparts-database.h and line > 34 is It is in gparts-login-ctrl.c on line 425. Currently, database support modules are loaded in gparts-login-ctrl.c in the function gparts_login_ctrl_instance_init(). > typedef struct _GPartsDatabase GPartsDatabase; > > but there is no "struct _GPartsDatabase" in the entire source code. - does > this compile? > I think at least when the compiler tries to resolve a function call > containing "GPartsDatabase" > the bomb should blow up. GPartsDatabase is an interface in the GObject framework, so it is never instantiated. Both GPartsMySQLDatabase and GPartsPostgreSQLDatabase implement the interface. However, PostgreSQL support has not been implemented. These classes and interface make up the database abstraction layer. Other implementations could be created later, like SQLite, which has been requested. > Is there a special support for databases in glib/GDK/GTK? > If not, why (the fucking bloody hell) is 'database' (declared in > gparts-login-ctrl.c#416) > initialized with g_object_new() - remember, it's a pointer to a structure, > that's type is not defined? The call to g_object_new() would create GPartsMySQLDatabase (or GPartsPostgreSQLDatabase, but it is not implemented yet.)
