Make sure that the project is compiled with the -g compiler option. This ensures that the executable has debug symbols included. Please notice that for other compilers than GCC this might be a different switch.

Menu => Project => Build Options Set Project Build Options


Open The Debugger Watches Window

Open Watch Window


Find the line containing the variable to be watched. Set a breakpoint in a position that will allow you to observe the variable value.

Menu => Debug => Toggle Breakpoint Choose Watch Variable

Run the debugger until the breakpoint is reached. Right click the variable to set a watch in the Watch Window.

Notes:

Breakpoints may also be toggled with a left click in the left editor margin.

Breakpoints do not work in constructors or destructors. They do, however, work in routines called from them. This is a GDB restriction, not a bug.
