[Q] Build error LG F6

Someone has asked me to build cm-12.1 for the metroPCS LG F6 and I have been doing nothing but fixing errors all day. I am finally stumped on an error because my best friend, Google, doesn't seem to have answers I need lol.

Error:

Code:

---

frameworks/base/services/core/jni/com_android_server_location_GpsLocationProvider.cpp:66:14: error: 'GpsMeasurementInterface' does not name a type
 static const GpsMeasurementInterface* sGpsMeasurementInterface = NULL;
              ^

---

The way the tree I forked is setup is a little odd from others I have seen but it had cm11 building and booting. I'm not a genius when it comes to this stuff but if I had a guess, I would say it has something to do with this: https://github.com/AndroidAddict92/a.../tree/cm12/gps

Things I have done:
Updated gps source files in device tree from cm11 to 12.1
deleted the cm repo and ran a fresh repo sync

I would appreciate anyones help on this subject, thanks in advance
