Core compilation error - 1.6.18-beta-b0

Just trying the Blink sketch to test my installation and I get core compilation errors. Config is:

This works for me. I suspect this has to do with your previous installation problems. Do you still have this problem after switching to the new json?

The SAMC21 doesn't seem to have a AR_INTREF_1V0 defined (AR_INTREF_1V024 is defined) --- so I added this after line 87 in https://github.com/mattairtech/ArduinoCore-samd/blob/master/cores/arduino/wiring_analog.h

AR_INTREF_1V0 = 6,

This gets it to compile, though not sure if the analog would work as expected.

FWIW I had to do the same the same thing with Beta-b1. Compiles, not tested analog.
