Hi Fabrice,
is master (git master) supposed to work? I get weird message
from cmsd when I try to start Qserv (both worker and master):
------ [log in to unmask] phase 1 server initialization completed.
++++++ [log in to unmask] phase 2 server initialization started.
Plugin /usr/local/home/salnikov/dm-2294/lib/libxrdoss.so: undefined symbol: _ZN6google8protobuf8internal12kEmptyStringE osslib libxrdoss.so
------ [log in to unmask] phase 2 server initialization failed.
150313 12:30:02 15616 XrdProtocol: Protocol cmsd could not be loaded
------ cmsd [log in to unmask]:1094 initialization failed.
if I do 'ldd -r lib/libxrdoss.so' I indeed see few unresolved
symbols in it.
Cheers,
Andy
