本文介绍了解决QtSql中“No such file or directory”错误的方法。提供了两种解决方案：一是通过编辑profile文件并添加QT变量定义；二是修改qmake配置文件，加入相应的QT变量定义。
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
