| <h1>Debug overview</h1> |
| |
| <p>The debugger lets you see what's going on "inside" a program while it |
| executes.</p> |
| <p>In order to debug your application, you must use executables compiled for |
| debugging. These executables contain additional debug information that lets the |
| debugger make direct associations between the source code and the binaries |
| generated from that original source.</p> |
| <p>The CDT debugger uses GDB as the underlying debug engine. It translates each |
| user interface action into a sequence of GDB commands and processes the output from GDB to |
| display the current state of the program being debugged. </p> |
| <p><b>Tip:</b> Editing the source after compiling causes the line numbering to be out of |
| step because the debug information is tied directly to the source. Similarly, |
| debugging optimized binaries can also cause unexpected jumps in the execution |
| trace.</p> |
