Ahhhh! Fortunately I have never used the Qt installer, so hopefully I can breathe a sigh of relief over this :) I sit in Ubuntu, I can't even recall what I did to install Qt under Windoze :) -

hi, I try to follow the step of the link your showed. But there is no "Libs & Include Files" Module in mysql "Custom Install", and no file end with the /lib/opt in any my sql file.I tried the following code on cmd, but nothing work.
cd C:\Qt\5.12.6\mingw73_32\bin\ (where qmake is )
qmake -- MYSQL_INCDIR=E:/mysql-8.0.18-winx64/include "MYSQL_LIBDIR=C:/Program Files/MySQL/MySQL Server 8.0/lib"there is nothing happened.

I put the libmysql.dll in QT bin before the posted, but not work. thank you for you help.

@hehedaozuiteng said in QMYSQL driver not loaded, how to get the qsqlmysql.dll for qt5.12.6 ?:
I tried the following code on cmd, but nothing work.
I'm giving up - you simply don't care about the instructions and don't show us what we need to show and what we suggest you to do... why do you think anything will work inside C:\Qt\5.12.6\mingw73_32\bin\ when you want to compile the sql driver? Did you make sure the incdir and libdir are containing the files mentioned in my (second) instruction link?

Do not be mad man. I just not realize how to build sql-driver.
the cmd does not running the qmake, I do not install qmake before I used it so I though I have to move to the where qmake.exe is.
Now I am install the qmake, perhep this time work and reinstall the mysql. Mysql is combine into differents programs, I cannot find the include and "/lib/opt" folder in it. -
Can you tell me what is the file that include in the "incdir" and "libdir" folder ?
I reinstalled the mysql, but cannot find the folder such as your described in instruction. Thank you very much. -
in the hope i can help someone: I provide various versions of qsqlmysql.dll here on Github

Thank for you help anyway.
I solved it two days ago. BTW, I do not think 32 bit vision is useful, ( if I am wrong please point out.) Mysql's serves is only offer 64 bit, so the libmysql.dll is also 64 bits. That is why I cannot build the drive at first 2 days lol.If someone like me do not know this, he will kill his two days beautiful life XD.

When I run this "qmake -- MYSQL_INCDIR="%Mysql%/MySQL Server 8.0/include" MYSQL_LIBDIR="%Mysql%/MySQL Server 8.0/lib" " it's show me the message " QMake has two modes, one mode for generating project files based on some heuristics, and the other for generating makefiles. Normally you shouldn't need to specify a mode, as makefile generation is the default mode for qmake, but you may use this to test qmake on an existing project " How can i solve this?

@thecodemonkey Thank you so much. Your files solved my problem.
