== Converting old br2-external trees
|
||
|
|
|
||
|
|
Buildroot 2016.11 introduced a backward-incompatible change in the way
|
||
|
|
br2-external trees are handled. A minor change has to be made: adding
|
||
|
|
a name to your br2-external tree, see xref:outside-br-custom[].
|
||
|
|
|
||
|
|
This can be done very easily in just a few steps:
|
||
|
|
|
||
|
|
* First, create a new file named +external.desc+, at the root of your
|
||
|
|
br2-external tree, with a single line defining the name of your
|
||
|
|
br2-external tree:
|
||
|
|
+
|
||
|
|
----
|
||
|
|
$ echo 'name: NAME_OF_YOUR_TREE' >external.desc
|
||
|
|
----
|
||
|
|
+
|
||
|
|
.Note
|
||
|
|
Be careful when choosing a name: It has to be unique and be made
|
||
|
|
with only ASCII characters from the set +[A-Za-z0-9_]+.
|
||
|
|
|
||
|
|
* Then, change every occurence of +BR2_EXTERNAL+ in your br2-external
|
||
|
|
tree with the new variable:
|
||
|
|
+
|
||
|
|
----
|
||
|
|
$ find . -type f | xargs sed -i 's/BR2_EXTERNAL/BR2_EXTERNAL_NAME_OF_YOUR_TREE_PATH/g'
|
||
|
|
----
|
||
|
|
|
||
|
|
Now, your br2-external tree can be used with Buildroot 2016.11 onward.
|
||
|
|
|
||
|
|
.Note:
|
||
|
|
This change makes your br2-external tree incompatible with Buildroot
|
||
|
|
before 2016.11.
