Is it possible to include a library from another library using the Arduino IDE?

Question

I\'m trying to write an Arduino library (effectively a C++ class) which itself references another library I have installed in my Mac\'s ~/Documents/Arduino/libraries directo

Answer 1

This issue was solved in the Arduino 1.6.6 release. The release notes of 1.6.6 mention that library to library dependencies have been fixed.

Library to library dependencies: when your sketch imports a library, and that library uses another, the IDE will find out without you having to add a useless #include to your sketch

Updating your version to 1.6.6 or newer will resolve your problem.
