Building a component in OE
You have a local copy of the component repo in path/to/<component name>
You have a working OE build dir in /srv/webos-ports (To set this up, start here: )
You have a working knowledge of linux
You have the Android SDK Setup
You have your galaxy nexus rndis setup and working.
Add the following to the bottom of conf/local.conf
S_pn-luna-sysmgr = "path/to/<component name>"
Now you can build the component from your OE environment by
$ MACHINE=<machine name> bb -c compile -f <component name>
The output is hidden inside the build tree. Look into the path
tmp-glibc/work/<machine name>-webos-linux-gnueabi/<component name>/<version>/build
for the binary you have build and transfer it to the device
