15 <h1>Debug overview</h1> |
|
16 |
|
17 <p>The debugger lets you see what's going on "inside" a program while it |
|
18 executes.</p> |
|
19 <p>In order to debug your application, you must use executables compiled for |
|
20 debugging. These executables contain additional debug information that lets the |
|
21 debugger make direct associations between the source code and the binaries |
|
22 generated from that original source.</p> |
|
23 <p>The CDT debugger uses GDB as the underlying debug engine. It translates each |
|
24 user interface action into a sequence of GDB commands and processes the output from GDB to |
|
25 display the current state of the program being debugged. </p> |
|
26 <p><b>Tip:</b> Editing the source after compiling causes the line numbering to be out of |
|
27 step because the debug information is tied directly to the source. Similarly, |
|
28 debugging optimized binaries can also cause unexpected jumps in the execution |
|
29 trace.</p> |
