My guess is that your linker doesn't support the new symbol versioning
exports and since the symbols are hidden by default they aren't visible
in the shared library. Previously there was a bug (since Luminous and
the switch the cmake) where every public and private symbol was exported
by librados.
lld is largely compatible with GNU ld / gold on the command-line and
in linker scripts and version scripts. Can you provide the error you
see or an example of one of the symbols with incorrect visibility?
It could very be that the way versioning is introduced in the project is
not compatible with Clang, since the general compiler used is GCC.
I was afraid that that was going to be the counter question?? 8-(
This occurs while building Ceph, which is a "rather" large package
with a lot of include subpackages... and some local patches for things
that have not been send upstream.
But lets start with the error reported:

Not sure what you can make of this.
