User’s Guide<br />

When a component is included, any dependent components are automatically<br />

included. When a component is excluded, any dependent components are also<br />

excluded. In either case, a dialog box provides information about dependencies<br />

and the option of cancelling the requested action. For example, if you exclude<br />

POSIX clocks, the dialog box informs you that ANSI time component would be<br />

excluded (Figure 4-25).<br />

Exclude VxWorks Component<br />

! WARNING: The results of calculating dependencies is not necessarily identical for<br />

inclusion and removal. Including a component you previously excluded does not<br />

automatically include the components that were dependent on that component,<br />

and that were therefore excluded with it. For example, excluding the POSIX clocks<br />

component automatically excludes the ANSI time component, which is dependent on<br />

it. But if the POSIX clocks component is subsequently included, there are no<br />

components required by it, and the ANSI time component is not automatically<br />

included (Figure 4-26).<br />

You can also include folders of components. However, not all components in a<br />

folder are necessarily included by default (nor would it always be desirable to do<br />

so, as there might be conflicts between components). <strong>Tornado</strong> offers a choice about<br />

what components to include. For example, if you include target shell components,<br />

not all of the components are included by default, and you are prompted to accept<br />

or modify the default selection (Figure 4-27).<br />
