    Hi,

    how did you run macdeployqt??

    Have you checked everything is ok according to this (http://doc.qt.io/qt-5/osx-deployment.html)??

      Yes, i've checked everything.
      I simply run this:
      macdeployqt myapp.app

      i got this:
      ERROR: no file at "/opt/local/lib/mysql55/mysql/libmysqlclient.18.dylib"
      ERROR: no file at "/usr/local/lib/libpq.5.dylib"

        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

          @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.

                                  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/
