QMYSQL driver not found Qt 6.5.1, I've tried all I found online, without success

@thecodemonkey sqldrivers from plugin folder in src from qtbase folder, right? and then as you Said the Application folder of the Project I am creating, is it right?
@cpplegend by application folder I mean the folder, where the compiler creates the .exe file of your project, like this:
the sqldrivers folder can be either a subdirectory of the application folder (like this:
) ,or in the installation binary folder of Qt. On my system that would be for
MSVC: C:\Qt\6.5.1\msvc2019_64\plugins\sqldrivers (and for MinGW: C:\Qt\6.5.1\mingw_64\plugins\sqldrivers)both options (application folder and installation folder) should work

@thecodemonkey ok when I return home I will try

If I am not mistaken::-1: error: CMakeFiles/untitled1.dir/widget.cpp.obj:widget.cpp:(.text+0x3b): undefined reference to __imp__ZN12QSqlDatabaseD1Ev'widget.cpp.objindicates this has been compiled with MSVC (MSVC does.objfiles, MinGW does.o) and__imp__ZN12QSqlDatabaseD1Evleading__imp_also indicates MSVC rather than MinGW. [Also if you really have a file namedwidget.cpp.objsomewhere per the error message that is wrong, MSVC should be generatingwidget.objfromwidget.cpp, but that's another matter.]:-1: error: collect2.exe: error: ld returned 1 exit statuscollect2/ldindicates MinGW linker.(Assuming I am right) You really need to sort out whether you are using MSVC or MinGW once and for all, and make it consistent....

@JonB I am using mingw, I know that because its the only package I have installed between mingw and msvc
@cpplegend Then what about as @thecodemonkey said?
-
@cpplegend Did you link the Sql module in CMakeLists ?
-
@thecodemonkey @JonB how do I make it?
@cpplegend maybe it gets us further if you post your project here first, incl CMakeLists.txt
