Could not understand the exact error.
But the class which used is already tested. But when integrated into project faced such errors.

It could be just a path issue or cleaning up your project and rebuilding it.
Since you're on Windows, did you properly export your classes symbols ?
The technique is described here.
There is no dependency for the class used. And its already tested in my sample code(single class). But when it is moved into my project (i mean its with multiple classes), those errors are shown.
What do you mean by move ? How exactly is your project constructed ?
But when integrated into project faced such errors.
Maybe you have to run
qmaketo solve that problem.
i have deleted build folder and made qmake. But same error while building (In Debug mode).
But when its changed to release mode, there is no such error.
@yuvaram You can always provide some code so we can see what is going on.
