No. It is your host compiler. It can compile programs to run on your host (or any other x86 target with the same or higher architecture than your host is).

For any other architecture like ARM, PowerPC and MIPS you need a *separate* compiler (mostly called "toolchain" = Binutils + Libc + GNU Compiler Collection). And if you want to compiler your target's programs on your host this toolchain must be a cross-toolchain (runs on a different architecture than it creates code for).

uclinux sounds like an MMU less CPU (means _no_ x86). So don't try to use your host compiler anymore for this job.

0.22? Where did get such an old one?

You might be more successfull with a more recent toolchain. So visit Dan Kegels website again

and load the current one. And read especially:

BTW: To build it by your own might be the hardest way to get a cross toolchain (but you can learn a lot, how things are working).

Maybe you will find a ready-to-be-used-binary toolchain for your architecture? Where did you get your hardware from? Didn't you get software with this piece of hardware?
