Did you clone submodules?

git clone --recursive https://github.com/tandasat/DdiMon.git

when i did as you say,i got those errors and i have no idea where the problem is.my visual studio is 2019.can you help me?
error LNK2019 Unresolved external symbol _invoke_watson，The symbol in the function "protected: virtual void __cdecl stdext::bad_alloc::_Doraise(void)const " (?_Doraise@bad_alloc@stdext@@MEBAXXZ) Referenced DdiMon C:\Users\hunter\Desktop\myhv\new\DdiMon\DdiMon\shadow_hook.obj 1

It turned out that it is no longer possible to use the C standard library in the kernel mode with only _HAS_EXCEPTION 0 with VS 2019.

I was able to compile the project by adding those missing definitions. I do not know what the implication of this exactly but you can try and play with the project.

// in shadow_hook.cpp

Thank you very much.I solved this error

Hi @HuntFrank
Can you please described how did you sove it? (I am facing the same error)

Nevermind. I wrongly added ucrtd library. Now it builds.

LNK2001 "void (__cdecl* std::_Raise_handler)(class stdext::exception const &)" (?_Raise_handler@std@@3P6AXAEBVexception@stdext@@@ZEA).

How to fix it?

Since google appears to be pointing to this and there appears to be an issue with the latest Visual Studio version, I'm going to resurrect this issue. Sorry about that.

I was consistently able to resolve the issue by not using /std:latest but rather /std:c 20 (which to me is less limiting than having to enable exceptions and the problems exception handling can cause with the Address Sanitizer).

Hope this helps someone.
