Scope is a graphical GDB front-end with the normal functions you would expect (stepping, breakpoints, etc.), and a few notable features: * The comminication between Scope and gdb is asynchronous. * You can enter any gdb command, at any time. * All gdb I/O (along with some other messages) is displayed in a terminal-like "Debug Console". Whenever you find the GUI lacking, simply switch to that console and work directly with gdb. * 7-bit/Locale/UTF-8 support for values.

Geany is a small and lightweight integrated development environment using the GTK+ toolkit.
