[En-Nut-Discussion] Question about following the cross tool chain compilation in Mac osx

[Lucius Fox]

Hi,

I am trying to follow the following steps in setting up tool chain for ARM
compilation:

http://www.ethernut.de/en/documents/cross-toolchain-osx.html

Before I do anything in the document, I already have:

$ gcc --version
i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5490)

So how can I following the steps in the article for ARM compilation without
screwing up my existing environment?

Thank you.
