../../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...
但C++支持在类里定义非常量静态成员函数,如"static double average(){...};"。 误区二:在函数体内对非常量静态成员变量初始化。(xcode有提示)正确的方法是将初始化语句放到函数体外定义(在类中只有声明),然后在函数内以class::member的方式调用。 非常量静态成员的错误使用方法 综上,非常量静态成员变量需要在类...

C/C++ error: cannot assign to non-static data member within const member function ‘xxxx’ - 在 C++ 中,带有 const 修饰的成员函数(即常函数)内部不能修改成员变量的值,如果尝试修改成员变量的值,就会出现该错误
In the same way you initialize non-reference static members: //Foo.cpp const Foo & FooA::m_foo = fooObj1; Foo & FooA::m_foo2 = fooObj2; where fooObj1 and fooObj2 are global variables of type Foo. Note fooObj1 and fooObj2 must be initialized before m_foo and m_foo2, ot...

person.GetNameAndAddr(name, const_cast<string &>(static_cast<const string &>(string())); This just shows that you can use casting to lie to the compiler. Obviously, it would be much cleaner to declare and pass an unused automatic variable: string name; string unused; person.GetName...
