This layer provides support for the BACnet stack.  This is an open
source C implementation that produces a static C library and demo
BACNet client and server applications.

Build procedure
---------------

1/ Clone yocto/poky git repository
git clone git://git.yoctoproject.org/poky

2/ Clone meta-bacnet git repository
git clone git://github.com/evensonbryan/meta-bacnet.git meta-bacnet

3/ Initialize build directory
source oe-init-build-env build-poky

4/ Add meta-bacnet layer patch to bblayer configuration file
vim conf/bblayers.conf

# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
POKY_BBLAYERS_CONF_VERSION = "2"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \
  ##OEROOT##/meta-bacnet \
  ##OEROOT##/meta \
  ##OEROOT##/meta-yocto \
  ##OEROOT##/meta-yocto-bsp \
  "

5/ Edit local.conf to specify the machine, location of source archived, package type (rpm, deb or ipk)
for your specific BSP.  The BACnet stack is not machine specific.

6/ Build the BACnet stack.  This builds all the demo applications.
bitbake bacnet-stack

Customizing the build
---------------------
1/ Create a .bbappend in your custom layer:
touch <your-layer>/recipes-connectivity/bacnet-stack/bacnet-stack_%.bbappend

2/ In your .bbappend, change do_compile to build specific applications
Examples:
do_compile () {
    # NOTE: There are many macros for defining different behavior and including/removing different
    # code sections.  If you do not want the default settings, either define the macros here
    # or create a patch file to update their definition in the Makefiles.

    # Example macro definition: include BACnet MS/TP support
    BACDL_DEFINE=-DBACDL_MSTP=1

    # Example build 1: Build the demo applications
    make apps

    # Example build 2: Build the gateway demo
    make gateway
}

3/ Add new FILES and do_install definitions in your .bbappend based upon what was
changed in do_compile.  Example to include just the "Who-Is" demo application:
FILES_${PN} = " \
    ${bindir}/bacwi \
    "
...
do_install () {
    install -d ${D}${bindir}
    install -m 0755 ${S}/bin/bacwi ${D}${bindir}
}
