<para>Assigns different priorities to recipe files in different layers.</para>
|
||||
<para>This variable is useful in situations where the same package appears in
|
||||
more than one layer.
|
||||
Setting BBFILE_PRIORITY allows you to prioritize a
|
||||
layer against other layers that contain the same package - effectively
|
||||
letting you control the precedence for the multiple layers.
|
||||
The precedence established through this variable stands regardless of a
|
||||
layer's package version (PV variable).
|
||||
For example, a layer that has a package with a higher PV value but for
|
||||
which the BBFILE_PRIORITY is set to have a lower precedence still has a
|
||||
lower precedence.</para>
|
||||
<para>A larger value for the BBFILE_PRIORITY variable results in a higher
|
||||
precedence.
|
||||
For example, the value 6 has a higher precedence than the
|
||||
value 5.
|
||||
By default, the BBFILE_PRIORITY variable is set to the value 5.</para>
