<h1>Debugging a project</h1>
|
|
|
|
<p>The debugger lets you control the execution of your program by setting
|
|
breakpoints, suspending executed programs, stepping through your code, and
|
|
examining the contents of variables.</p>
|
|
<p>To debug a project:</p>
|
|
<ol>
|
|
<li>Click <strong>Run > Debug Configurations...</strong>.<p>The Debug Configurations dialog opens.</li>
|
|
<li>Double-click <strong>C/C++ Application</strong>.</li>
|
|
<li>In the <strong>Name</strong> field, type <strong>Hello World</strong>.</li>
|
|
<p>You can now select this debug launch configuration by name the next time
|
|
that you debug this project.</p>
|
|
<li>In the <strong>Project</strong> box, type or choose your project, e.g. <strong>HelloWorld</strong>.
|
|
<br>
|
|
Your executable should be selected under "C/C++ Application."
|
|
<br>If not, the <strong>Search Project</strong> button should find the executable in the project.
|
|
<p> </p>
|
|
</li>
|
|
<ul>
|
|
<li>If you see the error "[Debugger]: No debugger available", select the Debugger tab
|
|
and choose a valid debugger for your platform (e.g. gdb/mi).
|
|
</li>
|
|
</ul>
|
|
<li>Click <strong>Debug</strong>.</li>
|
|
<p>You will be prompted to switch to the Debug Perspective. Click <strong>Yes</strong></p>
|
|
<p>You will now see the debug perspective with the hello.exe application window open.
|
|
The C/C++ editor repositions in the perspective.</p>
|
|
<ul>
|
|
<li>If you see an error in the editor "Can't find source file" you can use the buttons provided
|
|
to point to your source file, e.g. "Locate File."
|
|
</li>
|
|
</ul>
|
|
<li>In the left margin of the main.cpp window, double-click to set a
|
|
breakpoint on:<br>
|
|
cout << "You just entered"
|
|
<br>You'll see an icon there indicating the breakpoint is set.</br>
|
|
</li>
|
|
<li>Click <strong>Run > Resume</strong>.
|
|
<br>Or, you can use the <strong>Resume</strong> button (green arrow) on the toolbar <em>of the Debug View</em>
|
|
</li>
|
|
<li>When prompted, in the Console view, type a value other than 'm', and hit Enter/Return.<br>
|
|
The breakpoint will be hit.</li>
|
|
<li>In the <strong>Variables</strong> view, verify that the variable is not 'm'.</li>
|
|
<li>Click <strong>Run > Resume</strong>.</li>
|
|
<li>When prompted, again type a value other than 'm' in the Console view, and press Enter/Return.</li>
|
|
<p>The breakpoint will be hit.</p>
|
|
<li>In the <strong>Variables</strong> view, verify that the variable is not 'm'.</li>
|
|
<li>In the <strong>Variables</strong> view, right-click the input variable, and select <strong>Change Value...</strong>
|
|
and type <strong>'m'</strong> <em>between the single quotes</em> and hit <strong>OK</strong>.</li>
|
|
<li>Click <strong>Run > Resume</strong>.</li>
|
|
<p>The output in the hello.exe application window is:<br>
|
|
"You just entered m, you need to enter m to exit."
|
|
<li>The application terminates and the debug session ends. The debug
|
|
perspective remains open.</li>
|
|
</ol>
