我在我的ubuntu 14.04lts中编译一个名为ROPTLIB（http://www.math.fsu.edu/ROPTLIB/）的开源代码时遇到了一个问题。我自己编写一个CMakeLists.txt来编译代码。但我不能用错误日志编译成功为follw：用作声明的抽象声明'const <匿名类>'

然而，当我发表意见
//const class {
//public:
// template<class T> // convertible to any type
// operator T*(void) const // of null non-member
// {

// } // pointer...
// template<class C, class T> // or any type of null

可以编译成功，但它会得到错误的答案。我试图在谷歌和其他论坛上搜索这个问题，但没有人能帮助我。 这里是我的CMakeLists.txt：

如果在使用内建的'nullptr'时给出错误的答案，则可能是由于完全不同的错误。 –
