When I look in a failed build tree I see what I saw in the
installed materials, though under a build path:

It looks like the lang/gcc13 and lang/gcc14 installed material
that I provided in a previous Email, other than path details.
Just what are you proposing that lang/gcc14 should change
related to the above?

Just what is wrong with the above that needs to change?

The "hidden symbol `__aeabi_unwind_cpp_pr0'" error message
below looks like the symbol was found to me. The problem
looks to instead be tied to a disallowed hidden symbol
status? Is this some sort of ABI mismatch that one side
or the other needs to be made to match to avoid the
disallowed status?
