build issue for C++: libprotobuf.so.11 may conflict with lipprotobuf.so.8

[gyz...@google.com]

I follow the instruction

 $ git clone -b $(curl -L http://grpc.io/release) https://github.com/grpc/grpc
 $ cd grpc
 $ git submodule update --init
 $ make

During the make, I got following error

[HOSTLD]  Linking ***/grpc/bins/opt/grpc_cpp_plugin

/usr/bin/ld: warning: libprotobuf.so.11, needed by //usr/local/lib/libprotoc.so, may conflict with libprotobuf.so.8

/usr/bin/ld: ***/grpc/objs/opt/src/compiler/cpp_plugin.o: undefined reference to symbol '_ZN6google8protobuf19FileDescriptorProto18kSyntaxFieldNumberE'

//usr/local/lib/libprotobuf.so.11: error adding symbols: DSO missing from command line

collect2: error: ld returned 1 exit status

make: *** [***/grpc/bins/opt/grpc_cpp_plugin] Error 1

I appreciate all the help.

One more information: I cannot find lipprotobug.so.8 in my system.

[fen...@google.com]

sudo apt-get remove libprotobuf8

It fixes it on my machine.
