This is very likely to be a regression with gtk-doc 1.3x (1.30 I think?), and will affect upstream builds equally. gtk-doc stopped generating files that would previously have been generated empty. This is a deliberate change by upstream (https://gitlab.gnome.org/GNOME/gtk-doc/issues/103) so it is unlikely to be reverted. The GNOME team tried to file bugs for this while gtk-doc 1.32 was only in experimental, but the mass-rebuild must have missed libpsl. Library maintainers can either solve this class of bug by not attempting to include the object tree at all, which for example is appropriate if the library does not include any GObject subclasses: https://gitlab.freedesktop.org/gstreamer/gst-libav/merge_requests/40 or by adding an empty <xi:fallback/> inside the <xi:include> element for ../xml/tree_index.sgml (meaning "if you can't, substitute the empty string instead") to return to the previous behaviour, similar to this in GTK's documentation: <index id="api-index-3-24" role="3.24"> <title>Index of new symbols in 3.24</title> <xi:include href="xml/api-index-3.24.xml"><xi:fallback /></xi:include> </index> Regards, smcv
