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

cpplegend

@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?

thecodemonkey

@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

@thecodemonkey now when I include the QSqlDatabase header file these errors occures: :-1: error: CMakeFiles/untitled1.dir/widget.cpp.obj:widget.cpp:(.text+0x3b): undefined reference to __imp__ZN12QSqlDatabaseD1Ev' :-1: error: CMakeFiles/untitled1.dir/widget.cpp.obj:widget.cpp:(.text+0x8b): undefined reference to __imp__ZN12QSqlDatabaseD1Ev'

@cpplegend Did you link the Sql module in CMakeLists ?

@cpplegend
If I am not mistaken:

:-1: error: CMakeFiles/untitled1.dir/widget.cpp.obj:widget.cpp:(.text+0x3b): undefined reference to __imp__ZN12QSqlDatabaseD1Ev'

widget.cpp.obj indicates this has been compiled with MSVC (MSVC does .obj files, MinGW does .o) and __imp__ZN12QSqlDatabaseD1Ev leading __imp_ also indicates MSVC rather than MinGW. [Also if you really have a file named widget.cpp.obj somewhere per the error message that is wrong, MSVC should be generating widget.obj from widget.cpp, but that's another matter.]

:-1: error: collect2.exe: error: ld returned 1 exit status

collect2/ld indicates 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

JonB

@cpplegend Then what about as @thecodemonkey said?

cpplegend

@thecodemonkey @JonB how do I make it?

thecodemonkey

@cpplegend maybe it gets us further if you post your project here first, incl CMakeLists.txt
