Mysterious Lazarus/MySQL problem

[JRBleau]

Hello, I have a mysterious problem.

My project raised exception class EInOutError with message:
"Can not load default MySQL library ("libmysql.dll" or "libmysql.dll"). Check your installation"

However, there's no problem with the connection at design time: I even see the data, but at run time, I get the message even when I don't explicitly load the library (I also get the message when I do explicitly load it.)

Has anyone else had this experience and does anyone know what to do about it?

Lazarus ver. 3.8; FPC ver: 3.2.2 x86_64-win64-win32/win64
Connection: TMySQL80Connection
MySQL 32/64-bit
libmysql.dll product version 8.0.42.0 (saved in the project directory)

TIA,

John Bleau

Are the IDE and the application both 64-bit ? if not, they require different DLLs

Thank you. I downloaded the latest version of Lazarus and it now works.
