Windows 10, QMYSQL driver not loaded, MySQL 8.0

SGaist

For some additional information if anything was added.

Are you sure the version of MySQL you installed is built for MinGW ?

One other thing, MySQL 8 might be too recent for Qt 5.11. IIRC, they replaced a custom boolean type they used by the boolean type so it might also be that.

Orcherder

I am not sure the version of MySQL was built for MinGW. How can I check that?

What version of MySQL would you recommend? -I just uninstalled MySQL 8.0 and installed MySQL 5.5

Orcherder

UPDATE: I have installed MySQL 5.5 and the MySQL Connector C 6.1.

MySQL is not detected.

You should NOT run 'mingw32-make install'.
Note that this build cannot be deployed to other machines or devices.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

You should rather install that in a patch without spaces as they are usually trouble.

Orcherder

I used paths without spaces with the same result. MySQL not detected. When I try to follow C:\PROGRA~2\MySQL\MYSQLC~1.1\lib\opt the path does not exist, but the path C:\PROGRA~2\MySQL\MYSQLC~1.1\lib\ does exist. Where am I going wrong?

Use the -v option to see exactly where it fails the tests for MySQL.

Orcherder

Thank you for your continued help!

Here is the output from qmake with -v. None of the sources succeed.

SGaist

Did you start from a clean state ?

Because I'm seeing include from MySQL 5.6.11

Orcherder

How can I ensure that I am starting from a clean state?

Orcherder

@SGaist Thank you for your direction.

Again, I am new to QT and MySQL. I'm not sure why it says MySQL 5.6.11 since I've never had that installed?!

I started with MySQL 8.0 but have changed to MySQL Server 5.5 (32 bit)
I have downloaded and installed MySQL Connector C 6.1.11
I uninstalled Qt and reinstalled. qt-unified-windows-x86-3.0.5-online
I used maintenaince tool to remove mingw32 and the Sources and then added them again

Still no MySQL detected! Is there something I need to do to clean the configuration before I type the command?

Latest from my command:

C:\Qt\5.11.2\Src\qtbase\src\plugins\sqldrivers>qmake -- -v MYSQL_INCDIR=C:\PROGRA~2\MySQL\MYSQLC~1.1\include MYSQL_LIBDIR=C:\PROGRA~2\MySQL\MYSQLC~1.1\lib

Qt is now configured for building. Just run 'mingw32-make'.
Once everything is built, Qt is installed.
You should NOT run 'mingw32-make install'.
Note that this build cannot be deployed to other machines or devices.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

SGaist

The most simple: don't build in the sources. Do it in a folder outside of Qt's source tree, so if you have something that's failing you can just nuke the folder and start anew.

Did you check where sqlcli.h is on your system exactly ?
