    You have to give more details. "Doesn't work" doesn't give enough information to help you. Do you have any error message ?

      seems that macqtdeploy has some hardcoded PATH for MySQL and PostgreSQL.

        @mcosta not it doesn't, macdeployqt parses the output of otool to get the dependencies of the libraries/plugins of Qt. AFAICT, the plugins are built with dependencies coming from MacPorts hence the libmysqlclient.18.dylib in /opt/local/lib/

            Then you have to do

            install_name_tool -change /opt/local/lib/mysql55/mysql/libmysqlclient.18.dylib /usr/local/mysql/PATH_TO_libmysqlclient.X.dylib PATH_TO_libqsqlmysql.dylib
            

            In any case, if you are not using it in your application, you can also ignore the message and remove the plugin from the bundle.

              Which version of OS X and Qt are you using ?

              I've corrected the example line

                      Now i got only Postgre error

                      ERROR: no file at "/usr/local/lib/libpq.5.dylib"

                      Does it mean that i have working mysql plugin?

                        You should, unless the libmysqlclient is very different from the one Qt was built with.

                          I have now mysql working, but i still can't have working app because of this:
                          ERROR: no file at "/usr/local/lib/libpq.5.dylib"

                          This is not very good approach: include all plug-ins w/out need of them.

                            That's the PostgreSQL plugin. Like I suggested before, just remove the plugins you don't need from your bundle.

                              As i answered before when removing all other plugins from the bundle, the app doesn't open!

                                I didn't suggest to remove all other plugins, just the SQL related plugins you don't use

                                      @SGaist Strangely the ERROR disappear and working app bundle was created w/out changing anything.Unfortunately the app created database.db in the path i set (in this case in the program.app/contents/MacOS but can't write inside!

                                      Starting the app from QT can write in to the db, but starting it outside Qt doesn't write, but creates it.

                                        You need to use a writable path (look at QStandardPaths) Writing in the bundle itself is not something to do and it's even prohibited if you use the App Store to distribute your application.
