<note>
|
||||
If you run BitBake from a directory outside of the
|
||||
<ulink url='&YOCTO_DOCS_DEV_URL;build-directory'>Build Directory</ulink>,
|
||||
you must be sure to set
|
||||
<filename>BBPATH</filename> to point to the
|
||||
Build Directory.
|
||||
Set the variable as you would any environment variable
|
||||
and then run BitBake:
|
||||
<literallayout class='monospaced'>
|
||||
$ BBPATH = "<build_directory>"
|
||||
$ export BBPATH
|
||||
$ bitbake <target>
