I would like to create a native compiler for an XScale Linux system.
My first attempt was to cross-compile the gcc suite using the x86-xscale cross compiler that I already have, but I am having trouble getting the configure parameters/options right.
First, what is the difference between --host, --build and --target?
Must --with-cpu be set to something? to what?
Is there an xscale tools how-to for setting the options, or an .rpm to download?
Thanks in advance.

Kevin,
--host is the system you are building this on (for eg: i686-linux)
--build is the cross compilation build (for eg: mips-linux. In your case xscale)
--target is the target for which it is being built (for eg: mips-linux. In your case xscale).
Not sure if there are tools/rpms for xscale. But you should be able to build it yourself...

That is a fascinating topic. It seems that gcc is constructed using Autoconf 2.13, and will not cross-build. The configure script (nothing short of 100k lines of auto-generated shell!) tries to run a test compilation, realizes that it is cross compiling, and bails out.
According to
It seems like such a trivial question, that if I can build a cross compiler, why can I not cross-build the same source to make a native compiler?
BTW, does anyone have a list of what is valid for those "mips-linux" or "xscale-elf" or "dogcat-tuesday" strings? The variability is really confusing: "mips-linux" "mips-unknown-linux" "mips-unknown-linux-gnu" all seem to have valid meaning in different contexts. A little Backus-Naur would go a long way here.
