Error building gcc 4.5.2 for AVR

[Omar Choudary <choudary.omar@gmail.com>]

Hello,

I am trying to build GCC 4.5.2 for the AVR target. See my script:
http://www.cl.cam.ac.uk/~osc22/files/install_avr_tools.sh

I have some troubles when building, see below, maybe you can
help me; thanks:

It seems the build cannot find the folder avr/libgcc, but why?


When running, the libgcc error above shows:
