It can be fixed:

1. use dll version v. 5.7.17.0

2. The error occurs because the OS version is 64-bit. Replace int variables with long ones in key places (I changed them everywhere in EAX_Mysql.mqh), as well as in calls in my programme

Do you think that a person has not fixed the code for 2.5 years and is waiting for an answer?

Hey man,

I am trying to run a backtest here and I get an error "Cannot call 'mysql_init', 'libmysql.dll' is not loaded".

Apparently he is not being able to load the DLL file but I checked and it is there. Any idea?

PS: I have the Allow DLL checked in the Terminal Options --> Expert Advisor
