c++ - #include 不包含标题

Question

如果您包括 #include <Dbghelp.h>例如，在控制台 C++ 应用程序中，它不会从头文件中获取任何定义，并且或多或少会出现类似的编译器错误，就好像根本不包含此头文件一样。

编译器错误如下:

1>------ Build started: Project: ConsoleDump, Configuration: Debug Win32 ------
1>  ConsoleDump.cpp
1>e:\projects\vs2015 projects\consoledump\consoledump\consoledump.cpp(23): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

出了什么问题？

Answer 1

您必须包含 <windows.h>之前<DbgHelp.h> , 如果项目使用 "Stdafx.h" , 它必须包含在其他所有内容之前。以下是正确的顺序:

#include "stdafx.h"
#include <windows.h>
#include <Dbghelp.h>

还要确保将 DbgHelp.lib 链接到“项目设置”>“链接器”>“输入”>“附加依赖项”。
