    I have qt installed on osx and I have postgresql installed. Unfortunately, when trying to run executable, I get the following error:

    QSqlDatabase: QPSQL driver not loaded
    QSqlDatabase: available drivers: QSQLITE QODBC3 QODBC

    It seems like the qpsql plugin for qt is not installed or available.

    $ qmake -query | grep plugins
    QT_INSTALL_PLUGINS:/usr/local/Cellar/qt/4.8.3/plugins
    cd /usr/local/Cellar/qt/4.8.3/plugins/sqldrivers
    $ ls
    libqsqlite.dylib libqsqlodbc.dylib libqsqlpsql.dylib

    How do I get the psql plugin installed?

        It returns the following:

        $ otool -L libqsqlpsql.dylib
        libqsqlpsql.dylib:
        libqsqlpsql.dylib (compatibility version 0.0.0, current version 0.0.0)

          Looks right, but one thing that I find strange is that it's not listed in the available plugins.

          Can you do the same on the other two plugins ?

            @SGaist, this is the output for the other two plugins:

            $ otool -L libqsqlite.dylib

            otool -L libqsqlodbc.dylib

              Ok, still looking good.

              What does lastError return ?
