    HI,

    have you installed QT with installer or building from sources??
    What happens if you run macdeploy with verbose setting

    macdeployqt -verbose=3 myapp.app 
    

    Once your problem is solved don't forget to:

    • Mark the thread as SOLVED using the Topic Tool menu
    • Vote up the answer(s) that helped you to solve the issue

      @mcosta said:

      -verbose=3

      i got this (no errors on the syntax!!!):
      Usage: macdeployqt app-bundle [options]

      Options:
      -verbose=<0-3> : 0 = no output, 1 = error/warning (default), 2 = normal, 3 = debug
      -no-plugins : Skip plugin deployment
      -dmg : Create a .dmg disk image
      -no-strip : Don't run 'strip' on the binaries
      -use-debug-libs : Deploy with debug versions of frameworks and plugins (implies -no-strip)
      -executable=<path> : Let the given executable use the deployed frameworks too
      -qmldir=<path> : Deploy imports used by .qml files in the given path
      -always-overwrite : Copy files even if the target file exists
      -codesign=<ident> : Run codesign with the given identity on all executables

      macdeployqt takes an application bundle as input and makes it
      self-contained by copying in the Qt frameworks and plugins that
      the application uses.

      Plugins related to a framework are copied in with the
      framework. The accessibilty, image formats, and text codec
      plugins are always copied, unless "-no-plugins" is specified.

      See the "Deploying an Application on Qt/Mac" topic in the
      documentation for more information about deployment on Mac OS X.

        Sorry,

        the right syntax is

        macdeployqt myapp.app -verbose=3

            I got the same error.

            BTW I think the application works (by default all sqldrivers plugins are copied)

            The installer installs sqlite, mysql, odbc and postgresql also if you don't have the libraries installed

            UPDATE Qt drivers are loaded at runtime so there's no way to understand which drivers are used; for this reason macdeplyqt copy all drivers

                Hi,

                Do you have the MySQL libraries installed in /opt ? (i.e. using macports) If not then the error message is normal.

                    Then you probably have the MySQL libraries in a path like /usr/local/mysql/. Right ?

                        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.

                            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/

                                      Which version of OS X and Qt are you using ?

                                      I've corrected the example line
