抽象宣言者 'const <anonymous class>'を宣言として使用C++

Question

ubuntu 14.04ltsにROPTLIB（http://www.math.fsu.edu/ROPTLIB/）というオープンソースをコンパイルすると問題が発生します。私は自分でコードをコンパイルするためにCMakeLists.txtを書きます。しかし、私はfollwとしてエラーログで正常にコンパイルすることはできません：私は

//const class { 
//public: 
// template<class T> // convertible to any type 
// operator T*(void) const // of null non-member 
// { 
//  return 0; 
// } // pointer... 
// template<class C, class T> // or any type of null 
// operator T C::*(void) const // member pointer... 
// { 
//  return 0; 
// } 
//private: 
// void operator&(void) const; // whose address can't be taken 
//} nullptr = {};

をしかし、それは正常にコンパイルすることができますが、それは間違った答えを得るでしょう。私はGoogleと他のフォーラムの両方で問題を検索しようとしますが、誰も私を助けることはできません。ここ は私のCMakeLists.txtです：
