Thanks Brad,
I run nm on those .so file, it prints 'no symbol'
Then with ldd librados.so, I don't see the libceph-common.so, instead:
jialin@cori12: ldd librados.so

I also found this thread: http://tracker.ceph.com/issues/14788
which looks similar to the error I run into, and that thread mentioned the version between the headers file and the .so file, I think in my case both of them are v10.2.10, which should ok.
Best,
Jialin,

$ nm -A -C *.so|grep is_provided_buffer
libceph-common.so:0000000000223df0 T
ceph::buffer::list::is_provided_buffer(char const*) const librados.so:00000000000bfef0 T
ceph::buffer::list::is_provided_buffer(char const*) const libradosstriper.so: U
ceph::buffer::list::is_provided_buffer(char const*) const 'ldd librados.so' shows it links to libceph-common.so so I suspect you
may need that library.
Don't forget that you need to tell the linker where to find these
libraries at runtime so you will need to pass something like
'-Wl,-rpath=/rados_install/lib' to the compiler so it finds the
correct versions of the libraries (you can check which ones it will
find with 'ldd librados_test'.
