23 We have the following windows:
24
25 1.) Main Window: Shows what we are ultimately building and how far we are. Includes status bar
26 2.) Thread Activity Window: Shows one status line for every concurrent bitbake thread.
27 3.) Command Line Window: Contains an interactive command line where you can interact w/ Bitbake.
28
29 Basic window layout is like that:
30
31 |---------------------------------------------------------|
32 | <Main Window> | <Thread Activity Window> |
33 | | 0: foo do_compile complete|
34 | Building Gtk+-2.6.10 | 1: bar do_patch complete |
35 | Status: 60% | ... |
36 | | ... |
37 | | ... |
38 |---------------------------------------------------------|
39 |<Command Line Window> |
40 |>>> which virtual/kernel |
41 |openzaurus-kernel |
42 |>>> _ |
