How to access Postgresql using QT in Windows

Question

Hi to all,

 I am developing an application using QtRuby and postgresql. I sucessfully developed and running sucessfully in Linux. Now i want to run the same application in windows. But i am failing to connect to database(Postgresql). I am getting the following errors:

 QSqlDatabase: QPSQL driver not loaded
 QSqlDatabase: available drivers: QSQLITE QODBC3 QODBC

Can any one help how to resolve my problem. I am waiting for your replies.

Answer 1

As the error message says, the QPSQL driver is not available for Qt to talk to Postgres with. Probably the plugin has not been compiled yet.

As this how-to indicates, you need to install the PostgreSQL developer libraries, and then manually build the Qt driver plugin. See the how-to for the exact commands.
