How to compile examples for Pixhawk

I would like to compile the example code ( AP_InertialSensor ) from the libraries for the Pixhawk.

I can successfully compile the main code for the Pixhawk while in the ardupilot directory using:
make px4-v2
This works great.

Where and what do I “make” in order to compile the AP_InertialSensor test?
How does this get to run afterwards?

Thanks

Everyone,
I eventually read a MAKE tutorial and got it working. ( RTFM !)

BTW, for the AP_InertialSensors example to compile, I had to add two missing(?) includes.
Who / where do I report this??

Thanks
