hey there, i'll preface this by saying i'm a smart guy, but no stretch of the imagination do i have any experience with this, nor any prior knowledge.

I've been trying to get Arduino programming going off of my n900, but i've run into some problems.

The dream:
Program Arduinos on the move, Usb host n900, vi/whatever coding app, compile gcc avr, then using the avr libs, upload to Arduino.

USBOTG: I've installed KP50, H-e-n GUI
AVR backend: i've been following a combination of these two guides (official guide taking highest priority)
unofficial: http://www.mbeckler.org/microcontrollers/avrgcc_build/
official: http://www.nongnu.org/avr-libc/user-...nstall_avr_gcc

Snag 1:
N900 resets/crashes after removing a usb device.

Snag 2:
configure: error: Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+.
I have build-essential installed, and when i apt-get libmpfr/libgmp3_2 (or whatever they're called) it is reportedly already installed.. ?

Thanks for reading!
