c++ - 无法弄清楚错误

Question

我试图让 google glog 与 windows 一起工作，但我遇到了这些我无法弄清楚的错误。

// Variables of type LogSeverity are widely taken to lie in the range
// [0, NUM_SEVERITIES-1].  Be careful to preserve this assumption if
// you ever need to change their values or add a new severity.
typedef int LogSeverity;

const int INFO = 0;
const int WARNING = 1; 
const int ERROR = 2;
const int FATAL = 3;
const int NUM_SEVERITIES = 4;

Answer 1

您不显示的代码有这一行:

#define INFO 0

这意味着您显示的代码在编译器看来是这样的:

const int 0 = 0;

当然不会编译。
