Windows/Linux/Mac Eclipse plugin to compile and upload arduino sketches

LuisSoares:
Can you explain me the correct process for adding the utility subfolder to the include path in eclipse?

You need to go into your project properties (right click the project and select properties)
There you can go to this window and add the utility subfolders to the "GNU C" and "GNU C++" languages

Best regards
Jantje

PS note you will see other values. That is perfectly normal.
