The format of MYSQL_VERSION_ID seems to be Mmmss (“M” == “major”, “mm” == “minor version”, “ss” == “sub-version”). According to the doc page <https://dev.mysql.com/doc/c-api/8.4/en/mysql-ssl-set.html> I linked, the preferred API was introduced in v8.0.35. It might be more hygienic to define a macro symbol like MYSQL_TLS_NEW_OPTIONS_API_VERSION, whose value is 80035. Of course that would have to be done in the PostFix source, but it might make clear what the #if test is dependent on. > Wietse > _______________________________________________ > Postfix-users mailing list -- postfix-users@postfix.org > To unsubscribe send an email to postfix-users-le...@postfix.org Cheers, - Bob
