    You called the wrong qmake so the wrong headers are picked up. Call the qmake from your Qt version you're trying to compile the plugin for (I would guess it's 5.15 and not 5.12).
    Same problem here: https://forum.qt.io/topic/121095/issues-connecting-qt-to-mysql/9

      tried to do so
      '~/Qt/5.15.2/gcc_64/bin/qmake -- PSQL_INCDIR=/usr/include/pgsql'
      Ok

      anton@home:~/Qt/5.15.2/Src/qtbase/src/plugins/sqldrivers$ ~/Qt/5.15.2/gcc_64/bin/qmake -- PSQL_INCDIR=/usr/include/pgsql
      
      Running configuration tests...
      Done running configuration tests.

      Qt is now configured for building. Just run 'make'.
      Once everything is built, you must run 'make install'.
      Qt will be installed into '/home/anton/Qt/5.15.2/gcc_64'.
      
      Prior to reconfiguration, make sure you remove any leftovers from
      the previous build.
      

      Ok, do it 'make sub-psql'
      And...

      anton@home:~/Qt/5.15.2/Src/qtbase/src/plugins/sqldrivers$ make sub-psql

        @Anton1978 said in Unable to compile SQL plugin:

        /usr/include/x86_64-linux-gnu/qt5/QtCore/5.12.8

        Still using the wrong include paths. Make sure to start with a clean source dir.

          I really don't understand why this is happening? I am explicitly specifying which qmake to use - '~/Qt/5.15.2/gcc_64/bin/qmake'
          Even if I write like this
          ~/Qt/5.15.2/gcc_64/bin/qmake -- PSQL_INCDIR=~/Qt/5.15.2/Src/qtbase/src/plugins/sqldrivers
          the result does not change
          why is the file used
          /usr/include/x86_64-linux-gnu/qt5/QtSql/5.12.8/QtSql/private/qsqldriver_p.h

          I think me need some rest

            Another interesting point, if you open the SQLPlagin project in QTCreator, you can see that the sources with errors
            /home/anton/Qt/5.15.2/Src/qtbase/src/plugins/sqldrivers/sqldrivers.pro
            have 3 errors

            /home/anton/Qt/5.15.2/Src/qtbase/src/plugins/sqldrivers/psql/qsql_psql.cpp:152: error: no matching constructor for initialization of 'QSqlDriverPrivate' 
            
            :-1: error: [Makefile:845: .obj/qsql_sqlite.o] Error 1
            
            /home/anton/Qt/5.15.2/Src/qtbase/src/plugins/sqldrivers/psql/qsql_psql.cpp:152: error: no matching function for call to ‘QSqlDriverPrivate::QSqlDriverPrivate(QSqlDriver::DbmsType)’
            /home/anton/Qt/5.15.2/Src/qtbase/src/plugins/sqldrivers/psql/qsql_psql.cpp:152:68: error: no matching function for call to ‘QSqlDriverPrivate::QSqlDriverPrivate(QSqlDriver::DbmsType)’
              152 |     QPSQLDriverPrivate() : QSqlDriverPrivate(QSqlDriver::PostgreSQL) {}
            

            He writes to me about these errors when using make.
            But for others it compiles.
            Some kind of mysticism.

              Again: start with a clean source dir and call the correct qmake.

                It is not necessary to compile the plugin but it is only necessary to install the client, in the case of Ubuntu it is enough with:

                sudo apt-get install libpq-dev
                

                If you want me to help you develop some work then you can write to my email: e.yllanescucho@gmal.com.

                    Hi,

                    As @Christian-Ehrlicher wrote, you have to clean the sources before starting fresh. There are also hidden files in the folder that you need to remove (you can find that here).

                    If you want to be on the safe side, you can even to an out of source build.

                      @Anton1978 It is very strange since I have tested an example in GH actions and it works correctly for me, on the other hand if you want to compile it recommends you delete the files generated by your incorrect execution. You can also follow my answer in SO:https://stackoverflow.com/a/65568190/6622587

                        This my question too)). The second day I am at war with this plugin.
                        Thanks for prompting me to git this plugin, it really helped, now it remains to figure out how to connect the compiled plugin to my QtCreator.

                          You only need to call "make install" after make, then it should work.

                          It would be interesting to know why the preinstalled plug-in doesn't work. To do so set QT_DEBUG_PLUGINS=1 before starting your app. Then you should see what is happening.
