Hi Federico,

to use your generated config.h file you have to wrap it in a vapi file
and the compile it with your project.

E.g. you have to write a config.vapi file like this:

[CCode (cprefix = "", lower_case_cprefix = "", cheader_filename =
"config.h")]
namespace Config {
        public const string VERSION;
        public const string PACKAGE_VERSION;
        public const string PACKAGE_STRING;
        public const string PACKAGE_DATA_DIR;
        public const string GETTEXT_PACKAGE;

        .... etc etc ....
}

and then compile it with your sources.

eg.

valac <your source files> --vapidir ./ --pkg config

or

valac <your source files> config.vapi

Cheers,
Andrea
