Hello World驱动程序无法正确编译 [英] Hello World driver won't compile correctly
问题描述
我开始进行驱动程序开发，但是我遵循了在此处在线遇到的一些教程，并且试图将驱动程序编译为简单的.sys文件.
I started out driver development, however I followed some tutorials I met online here and I am trying to compile my driver into a simple .sys file.
代码如下:
#include <ntddk.h>
#include <wdf.h>
#define UNREFERENCED_PARAMETER(P) (P)
VOID DriverUnload(PDRIVER_OBJECT driver)
{
DbgPrint("first:HelloWorld End！");
}
NTSTATUS DriverEntry(PDRIVER_OBJECT pDriverObject, PUNICODE_STRING pUnicodeString)
{
DbgPrint("first:HelloWorld Begin！");
pDriverObject->DriverUnload = DriverUnload;
return STATUS_SUCCESS;
}
我没有编译，而是得到了一个非常有趣的错误:
Rather than compile, I get this very funny error:
Error C2220 warning treated as error - no 'object' file generated MyHelloWorldDriver C:\Users\****\source\repos\MyHelloWorldDriver\MyHelloWorldDriver\main.c 7
我迷路了，因为我不知道从其他地方寻求答案.我检查了所有内容，并得到了一个有趣的错误，该错误恰好在Visual Studio的其他版本上正常工作.如果删除警告，则不会担心，它可以很好地编译并且不会向屏幕发送任何错误，为什么会这样?
I am lost as I dont know where else to seek answers from. I have checked and checked all and I get this funny error which happens to work fine on other versions of Visual studio. If I remove the warnings, I don't see it to have a worry, it compiles fine and does not send any errors to my screen, why is this so?
我正在使用Visual Studio 2019，显然我可能会缺少什么??
I am using Visual studio 2019, what could I apparently be missing ??
PS
我收到的警告看起来像这样
The warnings I get look like this

推荐答案
看起来像Visual Studio的问题: https://developercommunity.visualstudio. com/content/problem/549389/intellisense-error-e1097-because-intellisense-does.html
Looks like an issue with Visual Studio: https://developercommunity.visualstudio.com/content/problem/549389/intellisense-error-e1097-because-intellisense-does.html
这是该链接的副本:
对于Visual C ++ 2017 15.8版(编译器版本19.15.26726.0)，新的未记录的编译器选项/d1initall和 新属性__declspec(no_init_all)已添加到编译器. Intellisense(VS17和19)无法识别此属性，并表示未知.
With Visual C++ 2017 version 15.8 (compiler version 19.15.26726.0) a new undocumented Compiler option /d1initall and a new attribute __declspec(no_init_all) got added to the Compiler. Intellisense (VS17 and 19) does not recognize this attribute and says its unknown.
问题是Intellisense不知道no_init_all属性的存在.
The Problem is Intellisense not knowing about the existence of the no_init_all attribute.
此属性在正式的Windows SDK和WDK 10.0.18362.0头文件中使用， 这意味着Intellisense会针对包含以下内容的所有项目显示此错误 Windows套件\ 10 \ Include \ 10.0.18362.0 \ um \ winnt.h(588和1093行)或 Windows套件\ 10 \ Include \ 10.0.18362.0 \ km \ ntddk.h(第7597行).
This attribute is used in the official Windows SDK and WDK 10.0.18362.0 header files, that means Intellisense displays this error for all projects that include Windows Kits\10\Include\10.0.18362.0\um\winnt.h (Line 588 & 1093) or Windows Kits\10\Include\10.0.18362.0\km\ntddk.h (Line 7597).
您还可以通过简单地使用__declspec(no_init_all)属性定义结构来重现错误，
You can also reproduce the Error by simply defining a struct with __declspec(no_init_all) Attribute,
__ declspec(no_init_all)结构A {}; 编译良好，没有任何警告/错误，但Intellisense表示错误.
__declspec(no_init_all) struct A {}; This Compiles fine without any warnings/errors but Intellisense says its wrong.
它已于2019年4月29日修复.
It has been fixed on 29th of April, 2019.
