我有两个库 A 和 B。库 B 是我自己的库,我需要其中的“windows.h”。此外,对于某些功能,我需要使用第三方库 A。A 使用谷歌日志库,问题如下:

第一个错误是这样的:

Severity Code Description Project File Line Error C1189 #error:  ERROR macro is defined. Define GLOG_NO_ABBREVIATED_SEVERITIES before including logging.h

我在“Ah”之前定义了 GLOG_NO_ABBREVIATED_SEVERITIES,但在那之后出现了奇怪的链接错误。我已经测试了这里建议的所有解决方案,但没有一个有效。

在使用“windows.h”的项目中还有其他方法可以使用 glog 吗?

链接器错误是:

  1. GLOG_NO_ABBREVIATED_SEVERITIES在包含之前定义logging.h

     #define GLOG_NO_ABBREVIATED_SEVERITIES
     #include <windows.h>
     #include <glog/logging.h>
    
  2. 在 Visual Studio 中添加GLOG_NO_ABBREVIATED_SEVERITIES预处理器定义,即Project > Properties > C/C++ > Preprocessor.

我在添加 GLOG_NO_ABBREVIATED_SEVERITIES 后重新编译了 A,但没有任何改变。但是通过重新排序包含“Ah”和“windows.h”解决了这个问题。当我在“windows.h”之前包含“Ah”时,不会出现错误!!!我不明白链接器错误的真正原因是什么!– 付款人
