使用gcc最后生成可执行文件时,如果所依赖的库文件是C++写的,必须加上-lstdc++选项,否则会报一大堆C++的错误,比如: undefined reference to `operator delete(void*)' undefined reference to `operator new(unsigned int)' undefined reference to `std::_List_node_base::hook(std::_List_node_base*)' 这是...
public: inline bool operator==(Snapshot const&); //后来的cpp文件是这么写的: inline bool Snapshot::operator==(Snapshot const&snap) { 1. 2. 3. 4. 5. 然后报错是这样的: undefined reference to `Snapshot::operator== 1. 2. 随后把inline去掉就正常了。 网上查了一下问题原因如下所示: 如果...

g会自动进行C标准库的连接;用gcc连接C程序也可以,但需要人为指定连接C标准库(-lstdc++),否则就会出现undefined reference to __gxx_personality_v/0之类的错误。六、操作符重载C++提供了运算符重载机制。可以为自定义数据类型重载运算符。实现构造数据类型也可以像基本数据类型一样的运算特性。struct...
