Hi

Using latest git, I get 2 very weird errors

The first line of fts-xapian-plugin.h is

#include "lib.h" (nothing else before)

Your help welcome

Thank you so muich

I guess you fixed your xapian plugin also against main, instead of release-2.4.0. It probably needs some changes, if you did that.

This is what I get after doing autoreconf -vi and configure.
