My code works perfectly fine. But just when I add the below line:

cvDisplayOverlay("Camera", "Hey", 4000);

I get this error: unresolved external symbol extern C void __cdecl

I am unable to understand how can I remove the error?

Thanks

so in more detail to berak his remark, you need to get the sourcecode of opencv, rebuilt it completely with Qt support and then your function will work perfectly.
