How can I debug a program using scanf with ddd?

Question

When ddd encounters a scanf statement, it displays "Waiting until GDB gets ready" message. The debugging activity stops here. Please guide me of overcoming this bug.

I'm using an amd64 athlon processor.

I am surprised that so much time has elapsed on this, so although I know little about ddd, it seems very likely that the problem is simply that gdb is waiting for the program which is blocked on a read waiting for input on stdin. If you were running gdb directly, you could direct input to the program by using:

run < input-file

You need to give your program some input.
