Qt QPSQL Driver Issue

Question

I am trying to connect postgresql with a Qt SQL module. I successfully compiled the psql driver (src \ plugins \ sqldrivers \ psql). But when I try to connect postgresql, I get this message;

QSqlDatabase: QPSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL3 QMYSQL QODBC3 QODBC QPSQL7 QPSQL

I am using PostgreSQL 8.3, Qt 4.7.1 and Visual Studio 2008 on Windows XP SP3. (I also try this , but didn 't help)
