<p>Building projects consists of a new sbs-based build system (Raptor) that wraps build functionality around existing SDK build tools which invoke <span class="code">makmake</span> commands (e.g. <span class="code">bldmake bldfiles</span> and <span class="code">sbs build</span>).</p>

<p> The plug-ins provide extra functionality to set up suitable build configurations for Symbian OS C++ projects.  The initial selection of a build configuration is done when you create a project, as described in <a href="../CreatingNewProjects.html">Creating New Projects</a>. You can later <a href="prj_set_build_tgt.htm">change</a> the Active Build Configuration. A command is available (<b>Project &gt; <a href="../../reference/menus/build_all_targets.htm">Build All Configurations</a></b>) to build all the selected build configurations in a batch.</p>

  generate object code. The compiler flags syntax errors in the source files. Use the  <a href="../../reference/ProjectPreferences.html">Properties for &lt;project_name&gt;</a> dialog to control how the project is built. The following methods build a project:</p>

<ul>

    <li><b>Build All Configurations</b> (<span class="code">CTRL+ALT+A</span>) &#8212;builds all build configurations for a project</li>

  <li><b>Build Project</b> (<span class="code">CTRL+B</span>) &#8212;  builds the entire project if it has never been built before or on subsequent builds only those files that have changed since the last build operation</li>

    <li>Choose one of the following to build a project:</li>

        <table width="800" border="0" cellpadding="2" cellspacing="0">

            <tr valign="top">

                <th width="30%" class="Cell"><div align="left">From the ...</div></th>

                    <th width="70%" class="Cell"><div align="left">Do the following...</div></th>

                </tr>

                    <td class="Cell">Click the <b>Build</b> icon (<img src="../../projects/images/icon_build_project.png" alt="Build project icon" width="17" height="17" align="absmiddle">) on the toolbar</td>

            </tr>

            <tr valign="top">

                <td class="Cell"><b>Project</b></td>

                    <td class="Cell"><ol>

                            <li>Right-click the project              

                            <li>Select Build Project</li>

            </tr>

        </table>

        </ul>

  <p>Carbide.c++ builds the project. A build dialog  and a task bar appear during a build process. All build output  is shown in the Console view while build errors and warnings appear in the Problems view.</p>

  <p>Whether a full build or incremental build is requested, Carbide forwards the request to the SDK make system. The SDK make system determines if anything needs to be

      dependencies present.</p>

  <p>Projects are also built if you make a change to it and then click <b>Debug</b>. It may be useful to automatically save modified resources before a manual build process by enabling the <b>Save automatically before build</b> option in the <b>Window &gt; Preferences &gt; General &gt;</b> <img src="../../images/command_link.png" width="16" height="12"> <a class="command-link" href='javascript:executeCommand("org.eclipse.ui.window.preferences(preferencePageId=org.eclipse.ui.preferencePages.Workbench)")'> Workspace</a> preference panel. </p>

  <p class="note"><b>NOTE</b> If you want to turn off building before launching, uncheck the <b>Build (if required) before launching</b> option in the <b>Window &gt; Preferences &gt; Run/Debug &gt;<img src="../../images/command_link.png" width="16" height="12"> <a class="command-link" href='javascript:executeCommand("org.eclipse.ui.window.preferences(preferencePageId=org.eclipse.debug.ui.LaunchingPreferencePage)")'> Launching</a></b> preference panel.</p>

  <p>When performing a build, output is displayed in the <a href="../../reference/view_console.htm">Console</a> view. If you do not want to clear the console before each build you need to uncheck the option <b>Always clear console before building</b> in the <b>Build Console</b> panel. This option is enabled by default. You can access this panel by selecting <b>Window &gt; Preferences &gt; C/C++ &gt; Build &gt; <img src="../../images/command_link.png" width="16" height="12"> <a class="command-link" href='javascript:executeCommand("org.eclipse.ui.window.preferences(preferencePageId=org.eclipse.cdt.ui.preferneces.CBuildConsolePreferernces)")'> Build Console</a></b> preference panel (figure 4).</p>
