See jubatus-mpio instead
This frsyuki/mpio repository is suspended.
But thanks to an open-source project called Jubatus, mpio library is maintained as jubatus-mpio. I recommend to check the repository instead:
https://github.com/jubatus/jubatus-mpio
If you're looking for RPC (msgpack-rpc-cpp), here is the jubatus-msgpack-rpc/cpp:
https://github.com/jubatus/jubatus-msgpack-rpc/tree/master/cpp
