have some trouble with cross compile (386->ia64)

hello:
When I compile Gcc(3.0.2) to the target ia64 platform on platform of
i386, I counter some trouble.
The error message is :

You didn't specify headers for the target.

You need to copy /usr/include and /usr/lib from the target IA-64 machine onto the host IA-32 machine, and then use the configure options

	--with-headers=<...path to IA-64 headers...>
	--with-libs=<...path to IA-64 libs...>
