Before the OpenEmbedded build system can use your new layer,
you need to enable it.
To enable your layer, simply add your layer's path to the
BBLAYERS
variable in your conf/bblayers.conf
file,
which is found in the
Build Directory.
The following example shows how to enable a layer named
meta-mylayer
:
LCONF_VERSION = "6" BBPATH = "${TOPDIR}" BBFILES ?= "" BBLAYERS ?= " \ $HOME/poky/meta \ $HOME/poky/meta-yocto \ $HOME/poky/meta-yocto-bsp \ $HOME/poky/meta-mylayer \ " BBLAYERS_NON_REMOVABLE ?= " \ $HOME/poky/meta \ $HOME/poky/meta-yocto \ "
BitBake parses each conf/layer.conf
file
as specified in the BBLAYERS
variable
within the conf/bblayers.conf
file.
During the processing of each
conf/layer.conf
file, BitBake adds the
recipes, classes and configurations contained within the
particular layer to the source directory.
