The change of "Extern C" suggested by Timo actually solved the situation
Now, further question :
I put a "i_warning" at each of my functions, and I see in the log :

The error comes from the fact taht the "get_last_uid" is called without
selecting a mailbox first, and therefore there is of course no uid.
How come ?

Your help very welcome
PENDING QUESTIONS
1 - WHat does represent "subargs" in mail_search_args
2 - for rescan : who is responsible for passing again the new email ? Is
the Dovecot core sending again all the emails to index ? or the fts
shall somehow access the mailbox and read all emails ? Wouldn't just be
saying "delete all index and get_last_uid is now 0" the easy way ? or
the fts must process all emails (and block the current thread as a
mailbx maybe quite large)
3 - for get_last_uid : this uncertainity is very unclear. "If there is a
gap, then indexer first indexes all the missing" -> this mean at a
certain point, indexer maybe rebuilding a previous email, so *last* uid
is something different than max. And how indexer does know whther there
is a gap wihtout callong the fts backend (whch it does not as there are
no function for that) ?
Thank you
