Unresolved External including the aux_klib kernel library

Good Afternoon, so I have a question about including the aux_klib library in my Kernel Mode Driver, for some reason I get the same error for all aux_klib functions.

Error   1   error LNK2019: unresolved external symbol AuxKlibInitialize referenced in function "unsigned char __cdecl Main(struct MainInfo*)" (?MainInfo@@YAEPEAU__MainInfo@@@Z)

I did #pragma comment(lib, "aux_klib.lib") in my project and no luck, also the driver is coded in cpp. I also added the lib to my project and made sure it was x64 as that is the projects build architecture. I also tried including the function via extern "C" with out the header and just the lib but no luck, I also added all the library paths to the linker settings and what not. Any ideas are welcome!

Properties->Linker->Input->Additional Dependencies add "AUX_KLIB.LIB"

This worked for me

I had the same problem with linking Aux_klib.lib, so I set /VERBOSE:Lib.

Right click on the project -> Properties -> Linker -> General -> Show Progress

As I understand it, For Libraries Searched /VERBOSE:Lib shows the libraries search and I've noticed that Aux_klib.lib is not in that search. And I noticed another thing in the output, /NODEFAULTLIB is passed in the command line as well.

As @RbMm says,

are he search for aux_klib.lib may be you used /nodefaultlib option. in this case #pragma comment(lib, "aux_klib.lib") will be have no effect.

So I changed Ignore All Default Libraries

Right click on the project -> Properties -> Linker -> Input -> Ignore All Default Libraries

to No and everything linked and compiled perfectly.

TL;DR

In short, try to change Ignore All Default Libraries under Linker to No and use #pragma comment(lib, "aux_klib.lib").
