<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>
