    Re: QMYSQL I've got this problem, I'm trying everything I found online, someone said that you should build the driver by yourself, I found the documentation but I didn't understand what to do. Does someone knows how to solve this problem? I've been stuck on it for three days

    Hi and welcome to devnet,

    What exactly did you try ?
    What issues do you have ?
    Which platform are you on ?
    Which documentation did you follow ?

    @SGaist I'm currently trying to build the driver, I'm following the qt official documentation, I tried to copy the dll into the folder where all the sql libraries are(I'm working on windows 11). When I try to connect a mysql database it just says that QMYSQL driver isn't loaded

    (modiified) I'm trying to build the driver, now I am trying to build it using this line: mkdir build-sqldrivers
    cd build-sqldrivers

    qt-cmake -G Ninja <qt_installation_path>\Src\qtbase\src\plugins\sqldrivers -DCMAKE_INSTALL_PREFIX=<qt_installation_path><platform> -DMySQL_INCLUDE_DIR="C:\mysql-8.0.22-winx64\include" -DMySQL_LIBRARY="C:\mysql-8.0.22-winx64\lib\libmysql.lib"
    cmake --build .
    cmake --install .

    obviously I changed it with my personal paths, now the only error I get is:

    @cpplegend said in QMYSQL driver not found Qt 6.5.1, I've tried all I found online, without success:

    Version 6.7.0 of package Qt6

    ?? Where did this come from?

    @mzimmers from the prompt, I've tried what the official documentation says, you can find it here:https://doc.qt.io/qt-6/sql-driver.html, the title is "how to build the driver in Windows".

    @cpplegend
    @mzimmers is expressing surprise: you have downloaded/are trying to build for Qt 6.5.1 but the message indicates it is wanting "Version 6.7.0 of package Qt6". Qt 6.7 has not even been released.

    @JonB that's right, so I tried to put this line:-DQT_NO_PACKAGE_VERSION_CHECK=TRUE (not cheking the version of the package)
    resulting in this: C:\Qt\6.5.1\build-sqldrivers>qt-cmake -G Ninja C:\Qt\6.5.1\qtbase-dev\src\plugins\sqldrivers -DCMAKE_INSTALL_PREFIX=C:\Qt\win64 -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" -DQT_NO_PACKAGE_VERSION_CHECK=TRUE

    this are my paths.

    then I get this output:

    [9/22] Automatic MOC for target QMYSQLDriverPlugin
    ninja: build stopped: subcommand failed.

    obviously when I run "cmake --install ." it says:
    -- Install configuration: "Release"
    -- Installing: C:/Qt/win64/lib/cmake/Qt6Sql/Qt6QMYSQLDriverPluginConfig.cmake
    -- Installing: C:/Qt/win64/lib/cmake/Qt6Sql/Qt6QMYSQLDriverPluginConfigVersion.cmake
    -- Installing: C:/Qt/win64/lib/cmake/Qt6Sql/Qt6QMYSQLDriverPluginConfigVersionImpl.cmake
    CMake Error at mysql/cmake_install.cmake:49 (file):
    file INSTALL cannot find
    "C:/Qt/6.5.1/build-sqldrivers/plugins/sqldrivers/qsqlmysql.dll": No error.
    Call Stack (most recent call first):
    cmake_install.cmake:42 (include)

    I feel so stressed :(, I followed all the steps correctly, setted all the enviroment variables in order to run cmake, ninja, and the c and c++ compiler (gcc compiler) but the qsqlmysql.dll is not generated...

    I also asked chatgpt, it says that maybe I didn't configure corectly the qt package to support the mysql driver, should I delete my current package and install it again?

    @cpplegend
    Your compiler is MinGW while all the options are for MSVC.

    Sort out which compiler you are going to use. Maybe the QMYSQL driver builds only with one or the other, I don't know. My hunch is actually that you are intending/intended to use MSVC compiler.

    OTOH if you intended to use MinGW (Windows gcc) then

    qt-cmake -G Ninja <qt_installation_path>\Src\qtbase\src\plugins\sqldrivers -DCMAKE_INSTALL_PREFIX=<qt_installation_path><platform> -DMySQL_INCLUDE_DIR="C:\mysql-8.0.22-winx64\include" -DMySQL_LIBRARY="C:\mysql-8.0.22-winx64\lib\libmysql.lib"

    won't be right, where did you get that from?

    @cpplegend said in QMYSQL driver not found Qt 6.5.1, I've tried all I found online, without success:

    @JonB I got this line from the official qt documentation

    Does it say that line, which has -DMySQL_LIBRARY="C:\mysql-8.0.22-winx64\lib\libmysql.lib" can be used with the MinGW compiler?

    All your -Z... and other complaining options are for MSVC. .obj files are for MSVC. Your compiler is C:\PROGRA~1\CODEBL~1\MinGW\bin\C__~1.EXE. Where did you select to use a MinGW compiler with MSVC options for generating code?

    @JonB i don't know it just says:
    How to Build the QMYSQL Plugin on Windows
    You need to get the MySQL installation files (e.g. mysql-installer-web-community-8.0.22.0.msi or mariadb-connector-c-3.1.11-win64.msi). Run the installer, select custom installation and install the MySQL C Connector which matches your Qt installation (x86 or x64). After installation check that the needed files are there:

    <MySQL dir>/lib/libmysql.lib
    <MySQL dir>/lib/libmysql.dll
    <MySQL dir>/include/mysql.h
    and for MariaDB

    <MariaDB dir>/lib/libmariadb.lib
    <MariaDB dir>/lib/libmariadb.dll
    <MariaDB dir>/include/mysql.h
    Note: As of MySQL 8.0.19, the C Connector is no longer offered as a standalone installable component. Instead, you can get mysql.h and libmysql.* by installing the full MySQL Server (x64 only) or the MariaDB C Connector.

    Build the plugin as follows (here it is assumed that <MySQL dir> is C:\mysql-8.0.22-winx64):

    mkdir build-sqldrivers
    cd build-sqldrivers

    qt-cmake -G Ninja <qt_installation_path>\Src\qtbase\src\plugins\sqldrivers -DCMAKE_INSTALL_PREFIX=<qt_installation_path><platform> -DMySQL_INCLUDE_DIR="C:\mysql-8.0.22-winx64\include" -DMySQL_LIBRARY="C:\mysql-8.0.22-winx64\lib\libmysql.lib"
    cmake --build .
    cmake --install .

    When you distribute your application, remember to include libmysql.dll / libmariadb.dll in your installation package. It must be placed in the same folder as the application executable. libmysql.dll additionally needs the MSVC runtime libraries which can be installed with vcredist.exe

    this is the link: https://doc.qt.io/qt-6/sql-driver.html

    if I set the msvc compiler as an environment variable, will it work? so when I run that command it should take the msvc compiler, isn't it right?

    @cpplegend in addition to what @JonB said, I'd still like to know where that 6.7 is sneaking in. Can you show us the file C:/Qt/6.5.1/msvc2019_64/lib/cmake/Qt6/Qt6ConfigVersion.cmake, around line 53?

    @mzimmers I had a problem with the libraries and now I had to remove everything, some files were a problem for the qt framework (for exaple qt design didn't run) and I have deleted all, I am downloading the open source files again from qt, when I am done I will retry, if the error persists I will show you the problem

    MimerConfig.cmake
    mimer-config.cmake

    You mix Qt6.5.1 and Qt6 from current git - this can not work...

    @Christian-Ehrlicher could you tell more about it? I didn't understand, by the way I am installing it again, the open source Version of qt

    What should I say more ? You've two Qt versions on your system. The binary one is 6.5.1 and the source version 6.x from git obvoiusly. This can not work.

    @cpplegend somewhere along the line, you got multiple versions of Qt installed. You're doing the right thing by reinstalling. Other right things would be:

    • use the Qt online installer instead of just cloning the repo
    • use the Qt maintenance tool to add whatever components you need
    • use Qt Creator for your build
    • ditch all the MSVC stuff altogether.

    @mzimmers okok I am doing everything right for the moment, now I am not at home but when I return I will make you know how it is doing.
    @Christian-Ehrlicher @JonB @mzimmers @SGaist
    thanks to everyone, I am new in this ambient (I made only one Application to practice), so every response has been helpful
