get erro on ubunto but not on Windows

hi
i can't get Arduino UNO to work in ubunto get this erros

THX

That is the delay.h bug. There is an easy fix. The "line 426" in math.h is the giveaway.
That is the declaration for round().
You need to locate the file wiring.h, and comment out the define for round.

This bug is fixed in the Ubuntu repository (v0022) but not in v0023.

edit: That file should be in
../pro/arduino-0023/hardware/arduino/cores/arduino/

THX it works :smiley:
