I didn't get galileo yet but i tried to debug blinking sketch without the board and i got this error :
Arduino: 1.5.3 (Windows 7), Board: "Intel® Galileo"
i586-poky-linux-uclibc-g++: error: Files: No such file or directory
i586-poky-linux-uclibc-g++: error: (x86)\arduino-1.5.3/hardware/tools/x86/i586-poky-linux-uclibc: No such file or directory
This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
Any help !
