如何编译使用Windows.H和Google Glog(Glog/Loggging.h）的C 程序

How to compile a c++ program that uses both windows.h and google glog (glog/logging.h)?

本文关键字：Glog Loggging 程序 Google 编译 何编译 Windows      更新时间：2023-10-16

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Google Logging库，这是问题：

第一个错误是：

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

我在" a.h"之前定义了glog_no_abbreviated_severities，但是在出现了奇怪的链接错误之后。我已经测试了这里建议的所有解决方案，但它们都没有起作用。

在使用" Windows.h"的项目中使用GLOG的其他方法？

链接器错误是：

  1. 在包括logging.h

    之前定义GLOG_NO_ABBREVIATED_SEVERITIES 
     #define GLOG_NO_ABBREVIATED_SEVERITIES
 #include <windows.h>
 #include <glog/logging.h>

  2. 在Visual Studio中的预处理器定义中添加GLOG_NO_ABBREVIATED_SEVERITIES，即Project > Properties > C/C++ > Preprocessor。

我在添加glog_no_abbreviated_severities后重新编译A，但没有任何改变。但是，通过重新排序" A.H"answers" Windows.H"来解决问题。当我在" windows.h"之前包括" a.h"时，没有出现错误！！！我不明白链接器错误的真正原因是什么！ - Payman
