undefined reference to `ImageViewer::applyEffect()'

You have declared a slot called ImageViewer::applyEffect() but not implemented it.

how do u find compile error ?

IDEs can find error messages for you. Since errors are printed on the stderr, you can use "make > NUL" to filter out non-error messages.

what is this long list before the error message?

The lines starting with "mingw32-make" are from make which tells you what it's doing at the moment and the lines starting with "g++" are the actual commands that were used to compile your application.

what toold do you use to debug and to find error?

If your program compiles, but it doesn't work, you can use a debugger (for example gdb), but it's useful only if you don't know what your program does.
