    @Eternus said in Mysql can't connect on MacBook:

    path-to-your-executable-to-run-it

    You do realize that this is a placeholder text that you have to replace with the actual path to the executable you are trying to run ?

    On the other side, you can also define QT_DEBUG_PLUGINS environment variable in the Run part of the Project panel and start your application as usual.

            You do realize that is indicated precisely where you should do it in Qt Creator ?

                    I never said it would be the solution, the goal is to gather information about why the plugin is not loading in order to fix it. And be careful, the name of the variable is all in upper case.

                        The application output shows one thing: you are misusing the QSqlDatabase class. It also does not show the plugin loading debug data.

                        Did you add the QT_DEBUG_PLUGINS variable in Qt Creator like I suggested ? If so, did you set it to 1 ?

                                Due to a change of licence by Oracle, the MySQL prebuilt plugin cannot be provided. You have to build it yourself.

                                    Did you even try to read the related Qt's documentation ?

                                    It's explained there.
                                    There are also numerous thread on this forum about that subject.

                                        And what about following the documentation I linked ?

                                        Are you sure you are using the correct qmake executable ?
                                        Did you check the qmake output ?
                                        Did you check the make output ?

                                          https://doc.qt.io/qt-5/sql-driver.html

                                          cd $QTDIR/qtbase/src/plugins/sqldrivers -- i need write full path
                                          qmake -- MYSQL_PREFIX=/usr/local - this working..
                                          i stopped on this step : make sub-mysql
