I intend to make gir2pas the standard way to interface Gtk-X libs with Free Pascal compiler. So, feel free to mention it there. gir2pas code is located here: https://gitlab.com/freepascal.org/lazarus/lazarus/-/tree/main/tools/gir2pascal Code generated (with still some manual tweaks for now): https://gitlab.com/freepascal.org/lazarus/lazarus/-/tree/main/lcl/interfaces/gtk3/gtk3bindings > > > The reason I'm write to debian-devel is to know if we want to enforce the > > fact that typelib files shall be able to regenerate gir files for Bookworm. > > If this is the case, shall I raise severity to be release critical? > > What's the impact of the inability to generate the XML gir files for > gir1.2-harfbuzz on other packages? Not sure there is any impact if we can get gir file from -dev packages as Simon stated in his answer. > > Thanks, > James > > [1] - > https://gitlab.gnome.org/GNOME/gobject-introspection/-/blob/37bde613a7cb77e7399dafb25731e13208f0ae0b/girepository/gitypes.h#L410 > > [2] - > https://gitlab.gnome.org/GNOME/gobject-introspection/-/blob/37bde613a7cb77e7399dafb25731e13208f0ae0b/girepository/girwriter.c#L784 > Thank you for these pointers. It helps understanding the issue. -- Cheers, Abou Al Montacir
