Error c1083 QtSql

jsulm

@123456789 There is no such header file, it is called Qsql, http://doc.qt.io/qt-5/qsql.html
Edit: it is QtSql
C/C++ is case sensitive you know

@jsulm
Note: it's named QSql, not Qsql, which will at least matter under Linux if not Windoze....

To add to @JonB: the casing on the screenshot is wrong and yes it's important. It's QtSql.

@123456789 Show us Screenshot of .pro file.

QT += sql //Case-Sensitive

@123456789 After adding sql in your pro file: did you rerun qmake?
You should try following:

Delete build directory
Run qmake
Build
Also: why did you install 2 MinGW versions?

@123456789
Separate the code, put in next line QT += sql in .pro file,
Save all,
Close the qt project,
go to project file location,
delete ex3.pro.user,
open ex3 project,
Choose appropriate kit when configure project,
rebuild the project.
