Static compile and SQL

Hi all. I have problem with my application. I built static application like in this video-tutorial, but suddenly SQL support in my application stopped working. I don't have any ideas what happened bad. Maybe I must compile that again with another parameters? If so, then what?

My *.pro file, is this good?

Code:

---

QT       += core gui sql
 
CONFIG += libqsqlmysql4
CONFIG += libqsqlmysqld4
CONFIG += static
 
TARGET = game-launcher
TEMPLATE = app
 
 
SOURCES += main.cpp\
        mainwindow.cpp \
    login.cpp
 
HEADERS  += mainwindow.h \
    login.h
 
FORMS    += mainwindow.ui \
    login.ui
 
RESOURCES += \
    zasoby.qrc
 
RC_FILE = settings.cfg

Sorry for my bad english. :rolleyes:

Qt SQL functionality is implemented using plugins. Statically linked Qt cannot use dynamically loaded plugins so any require plugins must be built-in and explicitly loaded.
Static Plugins

Lines 3 and 4 of your PRO file don't make much sense.
You are missing the QTPLUGIN variable
You are probably missing the Q_IMPORT_PLUGIN() macro in your code

You will still need to deploy any database engine library your SQL support requires.
