echo.cc:29:51: error: reference to ‘_1’ is ambiguous boost::bind(&EchoServer::onMessage, this, _1, _2, _3)); about muduo-tutorial

I write the following code to confirm that the boost and cmake all rightly installed on my machine.
Is there any conflict between muduo and boost?

I use the echo.cc to replace one file "muduo/examples/protobuf/codec/server.cc" then build, it report the same error. It seems the error was caused by the code in echo.cc.

ocean@hp:~/MYGIT/muduo/examples/protobuf/codec$ cp ../../../../muduo-tutorial/src/echo.cc  server.cc
ocean@hp:~/MYGIT/muduo$ make -j8
