Not necessarily; the errors indicate that certain symbols which
ought to be included in libsvc.a did not appear to be there.
Could you run and send us the output of:

   $ ar t ~/chord-build/svc/.libs/libsvc.a
   $ ls -l ~/chord-build/svc/dhashgateway_prot*

You would expect to find dhashgateway_prot.o both in the library
and also an object file.

If they are not present, did your compile of chord generate any
other errors?  Did you build chord and your program with the
same version of gcc?

If you just need to use chord essentially for its locationtable, you
are probably better off using something like chord-socket to help you
out.  Linking into our world of C++ is (and has been for others)
a source of some difficulty.
