Is it not using stable APIs from those two shared libraries? i.e. QEMU
is compiled and linked against librbd/librados, but I can set
"LD_LIBRARY_PATH" to pull in development versions if needed.
It is using stable APIs, and yeah that would be a simpler solution.
We do sometimes change how ganesha uses those APIs, or add new
interfaces that ganesha might call (and only conditionally build in),
but that's more rare and can be handled in other ways. Let me look into
just setting LD_LIBRARY_PATH.
Thanks,
