Issue with Qt Application Connecting to MySQL Database - "Drivers Not Loaded"

[Veltroniv]

Hello everyone,

I hope you're doing well. I'm facing a problem with my Qt application, and I'm seeking some guidance to resolve it.

Description:
I have developed a Qt application that successfully connects to a MySQL database and performs various operations. During the development phase, I used the "windeploy" tool to deploy the application, and it worked flawlessly on my computer. However, when I shared it with others, they encountered an issue. The program fails to connect to the database and displays an error message stating, "drivers not loaded."

Possible Cause:
After some investigation, it seems that the problem might be related to missing or incorrect database drivers on the users' machines. When deploying the application, I probably didn't include all the necessary dependencies, which are crucial for establishing the connection to the MySQL database.

Request for Assistance:
I am seeking your help in identifying the exact steps I need to take to ensure the application can successfully connect to the MySQL database on any machine. What additional files or configurations do I need to include during deployment to address this issue?

Please guide me through the process of deploying a Qt application that uses a MySQL database correctly. Your expertise and advice would be immensely appreciated.

Thank you all for your time and support.

Use Dependency Walker or it's successor Dependencies to find out what dlls the Qt mysql plugin needs. Most likely it's libmysql.dll and it's dependent dlls (openssl libs)
