Using 2.2.x MySensors library in Sloeber (Eclipse Arduino IDE). Build errors. (Solved)

[Cravecode]

I wanted to use the 2.2.x development branch in my project. So, I swapped out the code that Sloeber adds when you add the MySensors 2.1.1 release version with the latest code from the Github repo.

Context: This is for a PIR motion sensor using the NRF24L01+ radio.

I.e.: Replace: /Applications/sloeber 4.app/Contents/Eclipse/arduinoPlugin/libraries/MySensors/2.1.1 with the contents of git clone https://github.com/mysensors/MySensors.git 2.1.1

I tried building my project (a PIR node), and got several build errors.

Example build errors:

make: *** [libraries/MySensors/hal/transport/MyTransportRF24.cpp.o] Error 1 MotionSensorBattery C/C++ Problem

To fix this, I simply excluded the ./hal directory from the build. Everything appears to work fine now.

I.e.: expand libraries > expand MySensors > right click the ./hal directory > Properties > select C/C++ Build > tick Exclude resource from build.

Can anyone shed some light on the work being done in the ./hal directory? Am I messing something up by excluding this from my build?
