Question

我有两个库A和B.库B是我自己的库，我需要“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，这是问题所在：

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，但之后出现了奇怪的链接错误。我已经测试了所有建议的解决方案here，但没有一个可行。

在使用“windows.h”的项目中是否还有其他方法可以使用glog？

链接器错误是：

Answer 1

添加GLOG_NO_ABBREVIATED_SEVERITIES后，我重新编译了A，但是没有任何变化。但是通过重新排序包含“ A.h”和“ windows.h”的内容解决了问题。当我在“ windows.h”之前包含“ A.h”时，没有错误出现！！！我不明白链接器错误的真正原因是什么！ –付款人

Answer 2

在包含super.addMouseListener(new java.awt.event.MouseAdapter() { @Override public void mouseEntered(java.awt.event.MouseEvent evt) { super.setIcon(imageIconHover); System.out.println("in"); } @Override public void mouseExited(java.awt.event.MouseEvent evt) { super.setIcon(imageIcon); System.out.println("out"); } });之前定义GLOG_NO_ABBREVIATED_SEVERITIES
```
logging.h
```
在Visual Studio的预处理器定义中添加#define GLOG_NO_ABBREVIATED_SEVERITIES #include <windows.h> #include <glog/logging.h>，即GLOG_NO_ABBREVIATED_SEVERITIES。

如何编译同时使用windows.h和google glog（glog / logging.h）的c ++程序？
