- Key expansion happens when the BitBake datastore is finalized
- just before BitBake expands overrides.
+ Key expansion happens when the BitBake datastore is finalized.
To better understand this, consider the following example:
<literallayout class='monospaced'>
A${B} = "X"
B = "2"
A2 = "Y"
</literallayout>
- In this case, after all the parsing is complete, and
- before any overrides are handled, BitBake expands
- <filename>${B}</filename> into "2".
+ In this case, after all the parsing is complete,
+ BitBake expands <filename>${B}</filename> into "2".
This expansion causes <filename>A2</filename>, which was
set to "Y" before the expansion, to become "X".
