The first element is not a trivial thing to find because it depends on how you want to build your kernel. The second is easier since it can be found at <A HREF="http://cvs.parisc-linux.org/" TARGET="_top" > the official CVS site</A >. First, we will discuss about <B CLASS="command" >GCC</B > compiler. Then, the preparation of the build will be explained.
