| <h1>Build overview</h1> |
| |
| <p>The CDT uses the same make utility and makefile used on the command line. |
| The CDT can generate makefiles automatically when you create a Managed Make C project |
| or a Managed Make C++ project. You have the option of creating a Standard Make C |
| project or a Standard Make C++ project and providing the makefile.</p> |
| |
| <h2>Required utilities</h2> |
| <p>In order to build your project, you need to install and configure the following utilities:</p> |
| |
| <ul> |
| <li>build (such as make)</li> |
| <li>compile (such as gcc, for more information, see |
| <a href="http://gcc.gnu.org">http://gcc.gnu.org</a>)</li> |
| </ul> |
| |
| <h2>Build terminology</h2> |
| |
| <p>The CDT uses a number of terms to describe the scope of the build. </p> |
| |
| <h3>Build Project</h3> |
| |
| <p>This is an incremental build (make all). Only the components affected by modified files in that particular |
| project are built.</p> |
| |
| <h3>Rebuild Project</h3> |
| |
| <p>Builds every file in the project whether or not a file has been modified since |
| the last build. A rebuild is a clean followed by a |
| build.</p> |
| |
| <p>For more information on builds, see:</p> |
| |
| <ul> |
| <li><b>Workbench User Guide > Concepts > Workbench > Builds</b></li> |
| <li><b>Workbench User Guide > Tasks > Building resources</b></li> |
| </ul> |
| |
| <p>Build-related information is displayed as follows:</p> |
| |
| <ul> |
| <li>The C-Build view displays the output of the make utility.</li> |
| <li>The Tasks view displays a list of compiler errors and warnings related to |
| your projects.</li> |
| <li>Makefile actions are displayed in the Make Targets view.</li> |
| </ul> |
| |
| <p>For more information about the Tasks view, see <b>Workbench User Guide > Reference > User interface information > Views and editors > Tasks |
| view</b>.</p> |
| |
| <h2>Build preferences</h2> |
| |
| <h3>Build order</h3> |
| |
| <p>If certain projects must be built before others, you can set the build order. |
| If your project refers to another project, the CDT must built the other project first. </p> |
| |
| <p>When you set the build order, the CDT does not rebuild projects that depend |
| on a project; you must rebuild all projects to ensure all changes are |
| propagated.</p> |
| |
| <p>For more information on build order, see <b>Workbench User Guide > Reference |
| > Preference > Build Order</b>.</p> |
| |
| <h3>Automatic save</h3> |
| |
| <p>The CDT will save all unsaved modified resources when you perform a manual |
| build. By default, this feature is disabled.</p> |
