如何避免这些错误？ [英] How to avoid these errors?

问题描述

错误C1083无法打开预编译的头文件：'.\Debug \D25.pch'：没有这样的文件或目录



我有什么试过：



错误LNK2019未解析的外部符号__declspec（dllimport）public：static struct CRuntimeClass * __stdcall cD25Dlg :: GetThisClass（void）（__ imp_？ GetThisClass @ cD25Dlg @@ SGPAUCRuntimeClass @@ XZ）函数protected：long __thiscall cSettings297Frame :: OnRequestShowTab（unsigned int，long）（？OnRequestShowTab @ cSettings297Frame @@ IAEJIJ @ Z）

Error C1083 Cannot open precompiled header file: '.\Debug\D25.pch': No such file or directory

What I have tried:

Error LNK2019 unresolved external symbol "__declspec(dllimport) public: static struct CRuntimeClass * __stdcall cD25Dlg::GetThisClass(void)" (__imp_?GetThisClass@cD25Dlg@@SGPAUCRuntimeClass@@XZ) referenced in function "protected: long __thiscall cSettings297Frame::OnRequestShowTab(unsigned int,long)" (?OnRequestShowTab@cSettings297Frame@@IAEJIJ@Z)

推荐答案

右键单击解决方案资源管理器中的项目。



导航到>属性>所有配置。



打开C / C ++树，然后打开>预编译标题。选择使用{/ Yu}



填写页眉文件字段 - 您的默认值应为pch.h



确保您的头文件包含pch.h并且#include已正确编辑



验证项目中是否有pch.cpp文件。如果不存在则创建。只应在顶部包含#include pch.h

查看此属性> AllConfigs。选择PreCompiled Header Create {/ Yc}。这将只绑定到pch.cpp



验证#include pch.h是所有源文件的第一行。

Right click on the project in solution explorer.

Navigate to >Properties >All Configurations.

Open the tree for C/C++ and then >Precompiled Headers. Select Use {/Yu}

Fill in the Header File field- yours should default to something like pch.h

Make sure your header files contain pch.h and that your #include is edited correctly

Verify you have a pch.cpp file in project. Create if not present. Should only contain #include pch.h at the top
View Properties >AllConfigs on this file. Select PreCompiled Header Create {/Yc}. This will bind to only pch.cpp

Verify that #include pch.h is the first line of all source files.

第一个错误表示您需要（重新）创建预编译的标头。请参阅项目设置中的编译器部分。



第二个错误表明链接器找不到 cD25Dlg :: GetThisClass 。可能是因为第一个错误，可能是因为一个源模块没有编译。

The first error indicates that you need to (re-)create your pre-compiled headers. See the Compiler section in the Project settings.

The second error indicates that the linker cannot find the definition of cD25Dlg::GetThisClass. Possibly because of the first error, possibly because one source module did not compile.
