I've been following the installation guide from https://www.azerothcore.org/wiki/digital-ocean-video-tutorial
During the compiling process, an my_bool error has occured and stopped the process. https://i.sstatic.net/YlK74.jpg
From the github issues, I could only find that this could be related to incorrect MySQL, and the solution is to use MariaBD but I already use MariaDB.
Apparently the issue was using an outdated version of mysql/mariadb.
It's better to either use mysql 5.7 or 8.0 or latest mariadb version.
