Qt compile-time error

Qt version: 4.5.2.

I am writing an open source program, however it doesn't compile (QObject::connect() call doesn't compile).

May anyone tell me why?


The source code is available here:

Thank you a lot.

your class PortScannerEngine should be derived from QObject. change

Code:

---

class PortScannerEngine

---

to

Code:

---

class PortScannerEngine : public QObject

---

P.S. by the way, do not attach small code. just insert it in your post

Thank you for your reply.

Although I had checked the QObject derivation, somehow I missed it.
