But on True Blue Debian systems I haven't gotten it to work. Ok, yesterday I installed Devaun 6.12.86 on an old laptop (i5-2450m) and installed mariadb 11.8.6. According to the web that version is compatible with Mysql 8.0. I created the database and table and added terry to the grant table. I then did a fresh compile and tried running it: fpc ImportCars.pas Free Pascal Compiler version 3.2.2+dfsg-46 [2025/02/08] for x86_64 Copyright (c) 1993-2021 by Florian Klaempfl and others Target OS: Linux for x86-64 Compiling ImportCars.pas Linking ImportCars 97 lines compiled, 0.3 sec ./ImportCars An unhandled exception occurred at $00000000004F54E9: EInOutError: Can not load default MySQL library ("libmysqlclient.so.21" or "libmysqlclient.so").
