+
+
+ The externalsrc class supports building software
+ from source code that is external to the OpenEmbedded build system.
+ Building software from an external source tree means that the build
+ system's normal fetch, unpack, and patch process is not used.
+
+
+
+ By default, the OpenEmbedded build system uses the
+ S and
+ B variables to
+ locate unpacked recipe source code and to build it, respectively.
+ When your recipe inherits the externalsrc class,
+ you use the
+ EXTERNALSRC
+ and
+ EXTERNALSRC_BUILD
+ variables to ultimately define S and
+ B.
+
+
+
+ By default, this class expects the source code to support recipe builds
+ that use the B
+ variable to point to the directory in which the OpenEmbedded build
+ system places the generated objects built from the recipes.
+ By default, the B directory is set to the
+ following, which is separate from the source directory
+ (S):
+
+ ${WORKDIR}/${BPN}/{PV}/
+
+ See these variables for more information:
+ WORKDIR,
+ BPN, and
+ PV,
+
