Hi!
Could someone explain how GCC can be cross-built for new architectures
now that it requires C++ to build? It seems to be that there is the
following dependency loop:
- Building libstdc++ for target requires a libc for the target
- Building libc for target requires a gcc for target
- Building gcc for target requires at least a g++ that cross-compiles
- The cross-g++ for the target requires a libstdc++ built for the target
For architectures that GCC is already built for, I hear that this will
be solved by ensuring GCC version N can be built by version N-1. But how
will this work for a new architecture, which doesn't yet have a GCC
built for it?
I apologise if this has been covered before, but I didn't find anything
searching back through the list.
Thanks
Sam
