R: R: Building a toolchain for LEON


Shouldn't I compile and install eCos sources before?
Up to now I have just the cvs repository and I am trying to compile and
install it, I don't have a ecosconfig yet.
Is my error trying to use the cross-compiler gcc instead of the classical
pre-installed one?
Sorry for all these silly question, but I am stilla beginner, as you should
have noticed!
