2568 | You might want to not only have BitBake look for | 2568 | BitBake allows a task to recursively depend on itself by |
2569 | dependencies of those tasks, but also have BitBake look | 2569 | referencing itself in the task list: |
2570 | for build-time and runtime dependencies of the dependent | ||
2571 | tasks as well. | ||
2572 | If that is the case, you need to reference the task name | ||
2573 | itself in the task list: | ||
2574 | <literallayout class='monospaced'> | 2570 | <literallayout class='monospaced'> |
2575 | do_a[recrdeptask] = "do_a do_b" | 2571 | do_a[recrdeptask] = "do_a do_b" |
2576 | </literallayout> | 2572 | </literallayout> |
2573 | In the same way as before, this means that the <filename>do_a</filename> | ||
2574 | and <filename>do_b</filename> tasks of the current recipe and all | ||
2575 | recipes reachable (by way of dependencies) from the recipe | ||
2576 | must run before the <filename>do_a</filename> task can run. In this | ||
2577 | case BitBake will ignore the current recipe's <filename>do_a</filename> | ||
2578 | task circular dependency on itself. | ||
