解释错误消息 "non-const static data member must be initialized out of line" 的含义 在C++中,如果一个类包含非const的静态数据成员,那么这个数据成员不能在类内部进行初始化。这是因为静态数据成员是属于类的,而不是属于类的某个特定对象的,所以它们的值必须在类外部进行定义和初始化。如果在类内部尝试初始化...
../../third_party/webrtc/pc/rtp_sender.h:187:32: error: non-const static data member must be initialized out of line 1. 2. 解决 解决方法: 将非const类型的静态变量拿到类外去初始化。 例子: // 错误定义方式 class Test { int a; const int b = 1; static int c = 2;//wrong } //...
int static length_ = 2; }; 会报错non-const static data member must be initialized out of line 解决方法: solu-1: 把此静态成员变量加设为const solu-1-eg. #include <iostream> class Cube { const int static length_ = 2; }; solu-2:把次静态成员变量放到类外定义 solu-2-eg. #include <i...
C++使用非常量静态成员(non-const static data member) 误区一:将非常量静态成员放到private里 非常量静态成员的错误使用方法 静态成员只跟类有关,是所有对象共有的属性,如果在类中初始化则意味着每个对象都初始化一次,这样就需要非静态成员了。非常量静态成员函数不可以在类中初始化,一定要在类外把类名作为命名空...

It must have worked!! (though I'm quite tired to try on the real program, it's 1:47 the late night right now here X| and I'm about to go to sleep) I did ALL you said with an exception, I didn't use struct but i used class (as mentioned in my question before) ...
