您的控制台视图是否打开？
Window-> Show View-> Console

I'm trying to debug a C program using Eclipse CDT-s debugger and gdb on a Windows7 system, and everything seems fine, except for the console not showing up, which is bad, because my program needs input at some points from the keyboard.
So how should I make Eclipse's debugger work properly?

Thank you.
