Hi Eric, thanks for the help. Indeed, my make-all-gcc seemed to be the problem. Somehow I missed that from Bingo's scripts while I was adapting the gnu-arm-cross build scripts (which was the start point, together with Bingo's scripts).
However, using the exact commands, i.e. "make all install clean" gives all sorts of errors. I've noticed that I need to issue 2 commands separately to work: make all make install The final script is available here and now works: http://www.cl.cam.ac.uk/~osc22/files/avr_gcc/install_avr_tools.sh Thanks.
