Hi,

I would suggest using ELDK. I have had an easy time setting it up in the past.

$ mount -o loop arm-2008-11-24.iso /mnt

$ cd /mnt

$ sudo ./install -d /opt/eldk-4.2

Now add "/opt/eldk-4.2/usr/bin/" to your PATH.  My preferred method is to instead do

$ export CROSS_COMPILE=/opt/eldk-4.2/usr/bin/arm-linux-

and use the $CROSS_COMPILE variable when setting the toolchains in my Makefiles. Hope this helps :-)
