Building ARM GNU Cross compiler

Question

A similiar (less descriptive) post is here.

I\'m trying to roll my own tool chain using recent releases on Ubuntu and was hoping there was enough of a Linux communit

Answer 1

Here is the HelenOS arm-32 toolchain installation script, this should do what you want with very little fiddling. I'm using it on Ubuntu now (I'm one of the HelenOS developers). It was written by Martin Decky:

Sorry for any line wrapping, should be easy to fix. If you want a pastebin or http link to get it, just leave a comment.
