<h1>Debugging a program</h1>
<p>You must create a debug launch configuration the first time you debug your
program.</p>
<p>To create a debug configuration:</p>
<ol>
<li>In C/C++ Projects view, select a project.
</li>
<li>Click <b>Run > Debug</b>.</li>
<li>In the Debug dialog box, select a debug configuration type from the <b>Configurations</b>
list.</li>
<li><p>Click <b>New</b>.</p></li>
<li>In the <b>Name</b> box, type a descriptive name for this debug configuration.</li>
<li>In the <b>Project</b> box, type the name of the project containing
the application you want to debug.</li>
<li>In the <b>C/C++ Application</b> box, type the name of the executable
that you want to run.</li>
<li>Click the <b>Debugger</b> tab.</li>
<li>Select <b>Run program in debugger</b>.</li>
<li>Select the <b>Stop at main() on startup</b> checkbox.</li>
<li>Click <b>Debug</b>.</li>
<p>The debug perspective is opened and the application window opens on
top. The C/C++ editor window is repositioned in the perspective.</p>
</ol>
<p>For more information:</p>
<ul><li>To specify the
execution arguments an application uses and the working directory for a run
configuration, see <a href="cdt_t_run_arg.htm">Specifying execution arguments</a>.</li><li>To set the environment variables
and values to use when an application runs, see <a href="cdt_t_run_env.htm">
Setting environment variables</a></li>
<li>To select a debugger to use when debugging an application, see
<a href="cdt_t_run_dbg.htm">Selecting a debugger</a></li>
<li>To specify the location of source files used when debugging a C or C++
application, see <a href="cdt_t_run_source.htm">Specifying the location of
source files</a></li>
<li>To specify where the run configuration is stored, how you access it and
what perspective to open when running an application, see
<a href="cdt_t_run_com.htm">Specifying the location of the run configuration</a></li></ul>
<p>To use a debug configuration:</p>
<p>You can reuse a previously created debug launch configuration to debug your
program.</p>
<ol>
<li>Click <b>Run > Debug</b>.</li>
<li>In the Debug dialog box, select a debug configuration from the Configurations
list.</li>
<li>Click <b>Debug</b>. </li>
