Hello,
In my Qt program 32 bits, I make a connexion to a PostgreSql DB.

On my development computer (W7 64bits), in release mode, it works but when I try on a W7 32 bits computer without Qt installed : "driver not loaded".

Before
Qt Code:
  1. db = QSqlDatabase::addDatabase("QPSQL");
To copy to clipboard, switch view to plain text mode 
I add a trace to display the list of available drivers coming from
Qt Code:
  1. QSqlDatabase::drivers();
To copy to clipboard, switch view to plain text mode 

On the dev computer : "QSQLITE", "QMYSQL", "QMYSQL3", "QODBC", "QODBC3", "QPSQL", "QPSQL7"
on the other computer : nothing !

Something is missing but what ?
