I have downloaded a library that use "enum class ... : ..." types. It requires C++ 11 to compile correctly. When I have tried to compile selecting mbili board, console has launched an error. Searching in google and library's github page, I have found that, as I have writen before, C++ 11 is required to properly compilation.
Since Arduino IDE 1.6.X, C++ 11 is set by default. At default arduino/avr/platform.txt, at compiler.cpp.flags statement you can find -std=gnu++11. However, at sodaq/avr/platform.txt this flag is not found so C++11 compilation failed. I have added this flag to sodaq/avr/platform.txt and now, compilation and examples work great.
Please, could you modify and solve it on your definitions? This way, I needn't modify all my computers manually.
