glog on visual studio 2015

Question

我正在尝试使用Visual 2015在windows上构建Google库。在Windows上添加#include以绕过std::min问题后，我将看到以下两个主要错误(1次重复几次)。

1>c:\glog\glog-0.3.3\src\windows\port.h(117): warning C4005: 'va_copy': macro redefinition

编译器生成的move函数似乎是一个问题，但显式删除它也不起作用。

LogMessage(&)= delete；

有什么想法吗？

干杯，迈克

Answer 1

生成的函数不是LogMessage(&)= delete；

但它是：

LogStream::LogStream(google::LogMessage::LogStream &&)

Internaly将尝试调用LogStream的复制构造函数，从而调用被标记为已删除的ostream。

解决方案：

在LogStream类中声明：

 LogStream(const LogStream&) = delete;

 LogStream& operator=(const LogStream&) = delete;;
