MySQL version mismatched (SOLVED) lazarus / 16-Databases ---------------------------------------------------------------------- Middlecope · 2015-11-19 15:26 I had to reinstall fpc and lazarus. This time for my program I used TMySQL55conn Unfortunately while connecting I got the exception: expected client 5.5 got 10.0.21 I got rid of this error with the solution described in: http://forum.lazarus.freepascal.org/index.php/topic,16290.msg88163.htm l#msg88163 Now the program runs fine! I still do not know what the consequences are. How can this be solved in a eligant way? Is there a MySQL wizzard on the forum that can give a comment Thanks Teunis ---------------------------------------------------------------------- LacaK · 2015-11-19 19:45 You did it correctly  FYI: upcoming FPC 3.0 has already implemented support for MariaDB client library (10.0 is alias to 5.6) Of course next releases will cause problems again as far as MySQL often changes binary compatibility at ABI level.
