I am using QT Creator 1.2.1 based on QT4.5.3
Upon compiling the project i was working on, I had this
C:/Documents and Settings/L311c07/My Documents/TagIT/../../../../Qt/2009.04/qt/include/QtCore/../../src/corelib/kernel/qobjectdefs.h:52: error: `QtValidLicenseForCoreModule' does not name a type
I tried tracing the problem, and found that probably by including the file "connection.h" [which can be retrieve from qt demos] inside any cpp/header files will spring this error.
Would appreciate any help to resolve this!
