ExSystemTimeToLocalTime() not found problem SOLVED

NTDEV
1

I just wanted to thank you guys for helping.

I turns out that if I take the declaration ExSystemTimeToLocalTime() out
of ntddk.h, and put it in my CPP file, it compiles fine, but won’t link.
What I then did was to put an

extern “C”

block around it so the name gets mangled (or non-mangled in this case)
correctly for the linker, and sure enough, the linker found it in
ntoskrnl.lib.

Thanks again!

Cheers,

Get rid of your local definition in your header and wrap the #include of
ntddk.h / wdm.h in an extern “C” like this

extern “C” {
#include <ntddk.h> // or wdm.h if that is what you are using
}

And all symbols exported by ntos will then be resolved properly
