To build an OS image, you need to build the QNX System Builder project that contains the relevant buildfile. But unlike for other projects, the IDE doesn't create launch configurations for QNX System Builder projects, so you can't build them through the launch bar. Instead, you can use menu actions.
You build OS images simply by selecting the relevant project in the Project Explorer and choosing . Or, you can right-click the project entry and choose Build Project.
The Console view shows the output from the build attempt. Often, it's helpful to see only the messages related to the last build operation. Before building, you can clear the view by clicking the Clear Console button () in the view toolbar.
