如何防止宏重新定义

How to prevent macro redefinition(如何防止宏重新定义)

问题描述

在我的项目上工作了一段时间后，此警告开始出现:

After working some time on my project, this warning begins to appear:

2>Game.cpp
2>c:program filesmicrosoft sdkswindowsv6.0aincludewindef.h(126) : warning C4005: 'APIENTRY' : redefinición de macro
2>        c:usersferrandirectogameprojectsdev-libsglfwincludeglfw.h(72) : vea la definición anterior de 'APIENTRY'
2>c:program filesmicrosoft sdkswindowsv6.0aincludewingdi.h(23) : warning C4005: 'WINGDIAPI' : redefinición de macro
2>        c:usersferrandirectogameprojectsdev-libsglfwincludeglfw.h(88) : vea la definición anterior de 'WINGDIAPI'

我确定这是要解决的包含文件的顺序问题，因为这些文件都不是我的.我的问题是，是否有一种通用的方法可以防止这种情况发生，或者找到必须重新排序哪些文件以避免出现此消息.

I'm sure that it's a matter of the order of the include files to solve, because none of these files are mine. My question is if there is a generic way to prevent this or to find which files must to be reordered to avoid this message.

推荐答案

错误信息本身就是告诉你顺序错误.它说 windef.h 和 wingdi.h 正在重新定义在 glfw.h 中定义的符号.

The error message itself is telling you the incorrect order. It says that windef.h and wingdi.h are redefining symbols that were defined in glfw.h.

将 glfw.h 放在 Windows 包含文件之后.

Put glfw.h after the Windows include files.
