I got this same message type when I tried to compile the test program for an LCD keyboard. I was using version 1.6.4.
After looking around, somewhere I read a suggestion to try using an older version. After banging my head against the wall, I installed version 1.0.6 and viola! good compile and it worked as advertised.
I really didn't want to go backward in software version, so I downloaded the 1.6.5 Hourly build 2015/06/06 3:34. It worked correctly, the software compiled, loaded and run correctly.
So, my guess is it's a problem with a few versions, including 1.6.4. Apparently, it seems be fixed in the coming version.
The real question is, "How close is the beta to being done?"
I hope this gives a new perspective to the problem.
