Answer 1

大まかに説明すると、build の中で、C++でのソースのコンパイルに失敗しています。

../src/muddy-children-puzzle/model/muddy_protocol.pb.cc: In member function ‘virtual google::protobuf::Metadata protocol::Ask::GetMetadata() const’:
../src/muddy-children-puzzle/model/muddy_protocol.pb.cc:3182:67: error: ‘kIndexInFileMessages’ was not declared in this scope
   return ::protobuf_muddy_5fprotocol_2eproto::file_level_metadata[kIndexInFileMessages];

の中で、"../src/muddy-children-puzzle/model/muddy_protocol.pb.cc"はソースファイルの名前。
そこで定義されている関数GetMetadata、詳しくは、virtual google::protobuf::Metadata protocol::Ask::GetMetadata() constをコンパイルするときに、kIndexInFileMessagesの定義を読み込めなかった　ということになります。

一般的な解決方法は、

1. C++等に詳しくないのであれば、build は諦めて apt-get install できるパッケージを探す。
2. build が必須であれば、ソースコードが足りないの、足りないソースコードを探す。アレを入れてコレを入れる　みたいな手順で、アレを入れるのを忘れています。
