This isn’t a new feature, but it’s really useful when you’re debugging in eclipse, especially if you’re using the more advance or obscure features in GDB.
Basically, when you are debugging any program, there is a way to talk directly to GDB without using the point-and-click interface of Eclipse.
It’s called the GDB console.
It’s also really easy to find. When you are next running a debug session, just click on the console icon that is displayed in the console tab. The console usually shows your program output, but there is more than just one console!
