Hi

> the root of your troubles is your mixing of development and target in $ROOT

Yes, that's the point, I want to merge development and target due to
native compilation possibility (it's a development root filesystem) and
I want to keep clear the cross tool dir as much as possible.

I've started to play with rpath ld option and things are not to bad (the
libc is now found) but I continue to break on final link with other
libraries. I'm trying now to change the ld settings to include more
search path (when binutils are emerged)

If I can't get something good with new ld search path, then I will put
required libraries in /usr/CTARGET.

Thanks for your help.
