tree.hh不能在Ubuntu上編譯14.04

Question

我使用的是從http://tree.phi-sci.com/download.html最新的tree.hh。 它會產生錯誤（請參閱下文）。我該如何解決它？這個班怎麼會產生這麼多的錯誤？ 預先感謝您的建議？

tree.hh的示例：

64 template <class T, class tree_node_allocator = std::allocator<tree_node_<T> > > 
65 class tree { 
66   protected: 
67     typedef tree_node_<T> tree_node; 
68   public: 
69     /// Value of the data stored at a node. 
70     typedef T value_type; 
71 
72     class iterator_base; 
73     class pre_order_iterator; 
74     class post_order_iterator; 
75     class sibling_iterator; 
76  class leaf_iterator; 
77 
78     tree();           // empty constructor 
79     tree(const T&);         // constructor setting given element as head 
80     tree(const iterator_base&); 
81     tree(const tree<T, tree_node_allocator>&);  // copy constructor 
82     tree(tree<T, tree_node_allocator>&&);   // move constructor 
83     ~tree(); 
84     tree<T,tree_node_allocator>& operator=(const tree<T, tree_node_allocator>&); // copy assignment 
85     tree<T,tree_node_allocator>& operator=(tree<T, tree_node_allocator>&&);  // move assignment 
86 
87  /// Base class for iterators, only pointers stored, no traversal logic. 
88 #ifdef __SGI_STL_PORT 
89     class iterator_base : public stlport::bidirectional_iterator<T, ptrdiff_t> { 
90 #else

Answer 1

& &是C++ 11的功能。 在進行g ++調用時，您應該使用--std=c++11或--std=gnu++11命令行選項。
