I said it is obvious ;-)

I thought, I just did what is described on "All about toolchains"
.../mblaze-uclinux/documentation/toolchains.html

and forgot the "-c" switch, because you were talking about a.out there.
So, pretty much the last paragraph should state, that you shouldn't get 
any error messages, and the file "test.o" should be in this directory ...



As I said before, trying to get the whole toolchain/uclinux working on 
my machine (Fedora-Core-2) and checking the documentation on my way.
Hope it helps the next guy ;-)

cheers
