Re: devel/gobject-introspection on Darwin

Hi Brook,

Patrick Welche has already contacted upstream about that but he has not received any reply [1].
I'm going to do the same thing today or in the worst case tomorrow…
About their windows port…I'm making an environment to build glib2 on windows but I meet some problems with meson and the building of subprojects of glib2. Ironically making windows working for macos…:-).

Cheers,
Clément.
