default library?

Hi All,
I am trying to use geany as my compiler for arduino projects. When an arduino sketch opens, what libraries are being referenced?
Does anyone use geany as their compiler for arduino projects?

all of the libraries are located in:

<arduino dir>/hardware/arduino/cores/arduino

for the automatically included files (Arduino.h is the one that’s directly included) and

<arduino dir>/libraries
<sketchbook dir>/libraries

for libraries that you #include in your sketch.

Geany doesn’t appear to be a compiler — its website says both that it’s an IDE and that its a text editor. It’s probably best to just use the avr build of gcc unless you have a good reason not to.
