Hi John,
I didn't have either Mysql-8.0 or Mariadb-10.3 installed, either client or
server at the time. Another user Mark
reported having built 4.1 from the maint branch without any problem. I also
tried going back and rebuilding 3.905 and
3.10 and had the same problem. I am trying installing bot
Thanks John
That was indeed the problem. Downgrading libmysqlclient21 from
8.0.21ubuntu0.20.04.3 to 8.0.19-0ubuntu5 (sudo aptitude
install libmysqlclient21=8.0.19-0ubuntu5) did the trick as per this bug report
on Ubuntu re the opencv package,
