    You don't need to copy any files. Just use the full path to the executable.

        Understood.

        Went ahead and did that and it built the plugins in build_folder which is inside C:\Qt\6.4.3\msvc2019_65\ but not in the main path

        Then I tried to run

        C:\Qt\6.4.3\msvc2019_64\build_folder> cmake --build .
        

        *qt-cmake --build . threw an error

        the output remains

        3f27a5a5-3c8b-4e70-ab22-dbca009353d9-image.png

        While I was waiting for your response (thanks again!) I searched for an answer to those errors and it was suggested that I might need to modify the CMakeLists.txt at ...\src\plugins\sqldrivers . But beyond that i'm stuck,

          I think I was able to get a good build using

            @Thelonious said in (MySQL) qsqlmysql.dll doesn't get created.:

            My project still doesn't load QMYSQL

            Then set QT_DEBUG_PLUGINS to 1 before running your app and check the output to see why the MySQL plug-in was not loaded. Probably the mysql client library could not be found.

              In this case the plugin would at least show up in the available plugins list.
              I would guess it's the wrong Qt directory.

                So I should move my recently created qsqlmysql.dll into the same folder as my project executable? Do I need to move my plugins from C:\Qt\6.4.3\msvc2019_64\build-sqldrivers?

                  I never said this. I just think that C:\Qt\6.4.3\ is not the Qt you're using while running your executable. When you would have followed @jsulm's advise we would have known more.

                      @Thelonious said in (MySQL) qsqlmysql.dll doesn't get created.:

                      qt.core.plugin.factoryloader: "The plugin 'C:/Qt/6.4.3/msvc2019_64/plugins/sqldrivers/qsqlmysql.dll' uses incompatible Qt library. (Cannot mix debug and release libraries.)"
                      not a plugin

                      So you only compiled the release plugin but running a debug app.

                        I apologize; the QT help article on building MySQL drivers doesn't specify how to make a debug version. Can you please point me somewhere that explains the difference or shows me hot to make the debug plugin?

                          Either open the generated solution and build the debug version (can also be done from the command line but I don't remember the commands) or use -G Ninja or -G NMake Makefiles for the cmake generator - they both produce rules to create both plugins directly. Maybe we should add this to the documentation. MSBuild is not meant to be run on the command line and therefore has a lot of strange switches...

                            Interestingly enough after I run qt-cmake the only solution file I get is QSQLiteDriverPlugin.sln. Seems like a lot of people are having problems building the new driver.

                            How would I got about installing ninja for use with cmake? I downloaded CMake separately.

                            -Thanks

                                  @Thelonious You don't need it to set to anything. You have to make sure that the msvc environment is properly set up the same way you did it in your previous attempts.

                                    Still getting the same error.

                                    I might have to use SQLite while I build my code and come back to this. Something about my environment is just not right and the QT help article on building MySQL drivers seems to be missing a lot of explanations and is giving examples for a specific and out-of-date MySQL environment. The help article doesn't specify what directory any of these commands should be run from.

                                      Since you managed to set up your compiler environment before and no no longer I don't know what you're doing wrong. Call the correct vsvars batch file to set up your msvc compiler...

                                        The difference is I'm having to add

                                        -G Ninja
                                        

                                        to qt-cmake.

                                        I can make the plugins without it but when it comes time to --build the driver I get

                                        MSBuild version 17.5.1+f6fdcf537 for .NET Framework

                                          Your system is unclean, there's no reason for the projects to be in the bin folder of your Qt installation.
