fatal error: QtGui/QApplication: No such file or directory

Question

I\'m using Qt Creator, and this line is generated automatically by the Qt Creator:

#include

But, why am I getting this me

Answer 1

I had got same problem. From visual studio using Command Prompt(2010), I changed the path of prompt to where my Qt resides i.e. C:\Qt. There I set QTDIR environment variable.

c:\Qt> setx QTDIR C:\Qt

Then message was displayed:

SUCCESS: Specified value was saved.

Make sure VS is closed during this. When you reopen it, all headers will be detected.

I hope my solution will help anyone someday. Cheers :)
