You can configure your application projects in the Eclipse properties. Select the project in the Project Explorer view and go to the menu option Project > Properties, or right-click the project name and select Properties from the context menu.

From here you can define the following build settings:

Change the project toolchain

Configure an Autotools project

GNU Autotools automatically creates the required makefiles for an Autotool project. Prior to building, the Autotools plug-in runs the configure script. You can use the Configure Settings property page to set the configuration parameters to be passed:

  1. Right-click the desired project and select Properties.

  2. Select Autotools > Configure Settings entry from the list on the left. The right pane displays the options for the tools configure and autogen.

  3. Choose the tool section and configure the values on the right.

  4. When you finish, click Apply. Use Apply and Close to apply all the changes in the dialog and close it.

For more information, see the "Autotools Plug-in User Guide" at http://help.eclipse.org/index.jsp.

Change the active build configuration

By default, your projects have one or more build configurations. A build configuration is a profile that defines what is going to be built and how. For example, a Debug build configuration generates binaries with additional debug information, and a Release configuration provides the build tools with options to create a binary with the best performance.

The default build configurations depend on the project type:

  • Managed makefile projects: Debug and Release.

  • Standard makefile projects: Default.

  • Autotools projects: Build (GNU) and Debug (GNU).

You can create new build configurations from the C/C++ Build page of projects' properties.

To change the active build configuration:

  1. Select the project in the Project Explorer view.

  2. Right-click the project name and select Build Configurations > Set Active.

  3. Select the configuration.

You can also click the arrow next to the Build Active Configuration toolbar button. Then select the configuration from the list to trigger a build of the selected configuration.
