Hi, I was having trouble using the AVR headers as the Arduino IDE that came installed with the Udoo board did not find them. I then noticed that the place where they are supposed to be (<arduino dir>/hardware/tools/avr/avr/include/avr) did not exist. The headers are on the system and I can use them with a normal c program, but they weren't found by the Arduino IDE. I then thought a fresh re-install of the IDE might do the trick. I deleted the directory where all the arduino stuff is stored on the Udoo (/opt/arduino-1.5.4) and went ahead and downloaded the IDE from the Udoo's official website. After unzipping the package, I ran the binary file in it. Result: nothing. The program does not start, neither via the command line with the command "./arduino" nor via the GUI by double clicking it and running it. There is a short delay where it seems to be trying to start but then it crashes even before I get to see anything at all. I deleted the folder and reinstalled like 5 times now and there is no result at all. I guess I could download a new ubuntu image but I actually really don't want to do that just to have the Arduino IDE on the Udoo again. Please help
