Build Error for Multiperipheral Example

I have downloaded the example

//www.wsdof.com/sites/default/files/da14531-_da1458...

and have successfully run the Python link scipt. When I load the project and build it I receive indicating that app_db... is not defined. There are several conditional complilation ifdef's that I don't know enought about yet to see where the problem lies.

Where is the problem?
