I deleted all plugins , left only libqsqlite.dylib
The app doesn't work! -
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/

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.dylibIn any case, if you are not using it in your application, you can also ignore the message and remove the plugin from the bundle.

Which version of OS X and Qt are you using ?
I've corrected the example line

You're missing a slash before Users
-
You should, unless the libmysqlclient is very different from the one Qt was built with.

I have now mysql working, but i still can't have working app because of this:
ERROR: no file at "/usr/local/lib/libpq.5.dylib"This is not very good approach: include all plug-ins w/out need of them.
-
That's the PostgreSQL plugin. Like I suggested before, just remove the plugins you don't need from your bundle.

I didn't suggest to remove all other plugins, just the SQL related plugins you don't use
-
Start it from the command line, what does it tell you ?

@SGaist Strangely the ERROR disappear and working app bundle was created w/out changing anything.Unfortunately the app created database.db in the path i set (in this case in the program.app/contents/MacOS but can't write inside!
Starting the app from QT can write in to the db, but starting it outside Qt doesn't write, but creates it.

You need to use a writable path (look at QStandardPaths) Writing in the bundle itself is not something to do and it's even prohibited if you use the App Store to distribute your application.
