And there are no related changes on db_mysql AFAICT I would say you are missing dev libraries

[miconda]

I guess it was used with mysql 8.0.1, where my_bool type was removed -- patch above should be the fix, but it would require C99 compatible compiler. If master gets compiled/packaged without issues on the systems we build, then it should be ok.

[sergey-safarov]

@limitall could you test commit 1736723 or current master
if now master builds correctly, then please close ticket.

[miconda]

I am closing it, if something new appears and still a problem, reopen.

Just for reference: the fix referenced above caused a similar issue for MariaDB, it is now fixed in commit 9f459dc in master.
