Hi ,
i've a problem in mysql driver
the steps i make:
open Qt 5.15.1 (MinGW 8.1.0 32-bit)
then
cd plugins
cd sqldrivers
then
I runqmake -- MYSQL_INCDIR="D:\Connector C++ 8.0\include" MYSQL_LIBDIR="D:\Connector C++ 8.0\lib"i get this , should i change the path of compiler of windows to qt-mingw32 ? (i think no as long as i opened it)
D:\Qt\5.15.1\mingw81_32\plugins>qmake -- MYSQL_INCDIR="C:/Program Files/MySQL/My SQL Connector C 6.1/include" MYSQL_LIBDIR="C:/Program Files/MySQL/MySQL Connecto r C 6.1/lib" Usage: qmake [mode] [options] [files] 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 projectMode: -project Put qmake into project file generation mode In this mode qmake interprets [files] as files to be added to the .pro file. By default, all files with known source extensions are added. Note: The created .pro file probably will need to be edited. For example add the QT variable to specify what modules are required. -makefile Put qmake into makefile generation mode (default) In this mode qmake interprets files as project files to be processed, if skipped qmake will try to find a project file in your current working directorythen i used
qmake -project MYSQL_INCDIR="D:\Connector C++ 8.0\include" MYSQL_LIBDIR="D:\Connector C++ 8.0\lib"
made only sqldrivers.pro file but didn't install qmysql.dll file or other files

You don't follow the documentation. You have to use a clean source dir an go to the directory src\qtbase\src\plugins\sqldriver ...
-
i'm using Qt 5.15.1 and there is no such directory
these all dirs that contains sqldrivers Folder
-
You have to install the qt sources for a qt source dir...
-
Ah i see , i'm downloading it right now and try again if it worked i'll delete the post or mark it solved
Thanks
-
for sorry it didn't work either
the stpes i made open Qt 5.15.1 (MinGW 8.1.0 32-bit) ( ididnt use cmd at all )
because here is using cmd :https://forum.qt.io/topic/92626/cant-connect-to-mysql-database-qmysql-driver-not-loaded/17D:\Qt\5.15.1\Src\qtbase\src\plugins\sqldrivers>qmake -- MYSQL_INCDIR="D:\Connect or C++ 8.0\include" MYSQL_LIBDIR="D:\Connector C++ 8.0\lib" Running configuration tests...

Just run 'mingw32-make'. Once everything is built, you must run 'mingw32-make install'. Qt will be installed into 'D:\Qt\5.15.1\mingw81_32'. Prior to reconfiguration, make sure you remove any leftovers from the previous build.and this is output of the software

, but i downloaded mingw utilities and extract it in mingw81-32/bin -

MySql .................................. no
The third time: Please follow the documentation!
As you can see mysql was not configured, so take a look at config.log why this is the case. It's all written in the documentation.

i changed to mariadb because mysql client has alot of missing files
so i used
D:\Qt\5.15.1\Src\qtbase\src\plugins\sqldrivers>qmake -- MYSQL_INCDIR="C:\Program Files (x86)\MariaDB 10.0\include\mysql" MYSQL_LIBDIR="C:\Program Files (x86)\MariaDB 10.0\lib" and MYSql detected then mingw32-make sub-mysql then mingw32-make installand everything went very well
and i copied
qsqlmysql4.dll
qsqlmysql.dl
libqsqlmysql.ato dir D:\Qt\5.15.1\mingw81_32\bin
i test the software get
QSqlDatabase: available drivers: QSQLITE QMARIADB QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7 QSqlDatabasePrivate::addDatabase: duplicate connection name 'SecConnection', old connection removed. Donnne "Driver not loaded Driver not loaded"i have these files in D:\Qt\5.15.1\Src\qtbase\src\plugins\sqldrivers\plugins\sqldrivers
in this piece of code
Databas = QSqlDatabase::addDatabase("QMYSQL", "SecConnection");or this
Databas = QSqlDatabase::addDatabase("QMARIADB", "SecConnection");it gives me "Driver not loaded Driver not loaded"
when i use QODBC or QSQLITE
it loads successfully
so where is the problem i just want the diver to load and how to make it recognize Mariadb only
Thanks in advance

@MostafaEzzat
If you are having a "Driver not loaded" and don't know why, run your executable with environment variableQT_DEBUG_PLUGINS=1for diagnostic information. -
Sorry where should i put this variable QT_DEBUG_PLUGINS=1
do you mean by the environment .pro file ? or Options in qtcreator
-
@MostafaEzzat If you start from QtCreator then set it under "Projects/Build & Run/Run/Run Environment"
-
ok i went to Build Enviroment and added it , this output it seems it doesn't search for any sql plugins even he didn't search in

@MostafaEzzat I don't see it trying to load any SQL drivers. Do you have anything in plugins/sqldrivers directory of your Qt installation?
By the way: it should NOT search in qtbase/src/plugins/sqldrivers as that is source code directory, it should search in D:/Qt/5.15.1/mingw81_32/plugins/sqldrivers

@MostafaEzzat It still looks like you DO not follow the documentation (https://doc.qt.io/qt-5/sql-driver.html#building-the-drivers): after building you need to do "make install", that will copy the DLLs to your Qt installation.
Also, are you sure you used the correct qmake to build the plug-ins? I'm asking because you used qmake without absolute path.
