You probably forgot to implement the slot. Maybe you wanted it to be a signal and not a slot? The name seems to suggest so...

rerun qmake and all should be fine. (In the menu clear all etc.)

hi Wysota

ya name seems like a signal

but i have created a process using QProcess object and when it finishes i want to call this slot.
without wriiten anything in public slot:
it works fine but when i write void procFinished(); in public slot:
it is giving error that i mentioned.

But did you implement the slot?

Slots require code in both the .h and .cpp files. Paste the code you placed into the .cpp file.
