为什么易变静态成员初始化会产生重新定义编译错误？

Question

My Problem is the following:

I have a class with static counter. I set this counter as volatile because I use this variable in multithreaded environment.

class.h

class myClass
{
 public:
 volatile static int mCounter;
 (...)
};

class.cpp

int myclass::mCounter = 0;

In CPP file, I initialize it, and I obtain the following compilation error:

'mCounter' : redefinition; different type modifiers

Why ?

Thanks in Advance.

Answer 1

您还需要在该行上重复“ volatile”。
