error:QtSql:Nosuchfileordirectory

I wrote a program to test that how to connect to mysql with qt4,but I got the error message as follows when I compile it:

error: QtSql: No such file or directory

There are two method to solve this problem.

 

1.After execute qmake -project ,edit .pro file and add QT variable definition.

QT += sql

 

2.edit qmake configuration file,append QT variable definition

Just find the line like this:

QT += core gui network

change it :

QT += core gui network sql
