connect mysql qt creator 6.8.0

Ola, Meu qt não tem o prompt de comando, instalei todas as versões disponíveis, tudo, e não tem o prompt de comando.

Hello, My qt does not have the command prompt, I installed all available versions, everything, and it does not have the command prompt.

You are using Visual Studio and the Microsoft tool chain. If my memory serves, the Microsoft tools installs a Start menu shortcut to launch a command prompt set up for those tools.

Open the Microsoft VS developer command prompt (Use the Microsoft C++ toolset from the command line)
Run cl.exe (Microsoft's compiler) to test the environment is OK.
Execute {qtdir}\6.8.0\msvc\bin\qtenv2.bat to add Qt-specific elements to the environment
Run qmake -v to check that you have the correct Qt environment

obrigado pela atenção, eu fiz o que me sugeriu o resultado foi esse: QMake version 3.1
Using Qt version 6.8.0 in C:/Qt/6.8.0/msvc2022_64/lib
qual seria o próximo passo?

Quando eu executo esse comondo: C:\Qt\6.8.0\Src\configure.bat -sql-mysql -- -DMySQL_INCLUDE_DIR="C:\Program Files\MySQL\MySQL Connector C 6.1\include" -DMySQL_LIBRARY="C:\Program Files\MySQL\MySQL Connector C 6.1\lib\libmysql.lib"
Ele não reconhece esse arquivo: configure.bat, mas ele existe na pasta.

Sorry. Could someone help me? I don't understand anything about the platform, it's new to me, but I've been a programmer for a few years and I use Windows 64. I have version 6.8.0, I have installed C:\Program Files\MySQL\MySQL Connector C 6.1, I don't know if it helps, and I work as a local server with XAMPP, I also have Visual Studio 2022 Community installed. Thanks.

Hi, I tested some things from the link that was sent to me above, but it returns this error:
-- Configuring incomplete, errors occurred!
CMake Error at C:/Qt/6.7.2/Src/qtbase/cmake/QtProcessConfigureArgs.cmake:1077 (message):
CMake exited with code 1.

This:

C:\Qt\6.8.0\Src\configure.bat -sql-mysql -- -DMySQL_INCLUDE_DIR="C:\Program Files\MySQL\MySQL Connector C 6.1\include" -DMySQL_LIBRARY="C:\Program Files\MySQL\MySQL Connector C 6.1\lib\libmysql.lib"

looks like you are trying to configure to build all of Qt, not just the Mysql/Mariadb driver. The instructions are here and do not look like what you have done.

It only worked partly because it created a path:
C:\Qt\6.7.2\msvc2019_64\plugins\sqldrivers
The drive: qsqlmysql.dll
It is only connecting in release but not in debug.
Could you please continue helping me?

@Jeferson said in connect mysql qt creator 6.8.0:

It is only connecting in release but not in debug.

Because you only built the release plugin.

ChrisW67

Probably just requires this is in a fresh build directory

qt-cmake -DCMAKE_BUILD_TYPE=Debug -G Ninja ...
