user47021: I have the following setup:
- Arduino IDE for Mac 1.8.5
- RFDuino RFD220301
- CP2102 USB to UART connector
- Board set to "RFduino"
- port set correctly (but shouldn't matter as it is a compile error)
- Programmer: AVRISP mkII
When trying to compile an example script using BLE (Such as AdvertisementContinuous) I get the following error 
arm-none-eabi-g++: error: /var/folders/m6/mfwpb8b13wn4f9fvb4lhx_v40000gp/T/arduino_build_188605/core/syscalls.c.o: No such file or directory 
Any ideas?
Here's the -v log:

Error compiling for board RFduino.


user47021: So it appears solved: Using Arduino 1.6.13 I don't get the compile error. Must be an incompatibility with the RFduino Board libraries and the 1.8x IDE.

47021: <p>I have the following setup:
- Arduino IDE for Mac 1.8.5
- RFDuino RFD220301
- CP2102 USB to UART connector
- Board set to "RFduino"
- port set correctly (but shouldn't matter as it is a compile error)
- Programmer: AVRISP mkII</p>
