Link error LNK2019 redux

I reviewed the previous thread but couldn't resolve my issue using the info there. The errors I'm getting are:

Error 1 error LNK2019: unresolved external symbol __imp__SetupDiGetClassDevsA@16 referenced in function _main USBReaderC.obj

Error 2 error LNK2001: unresolved external symbol _USB_1208LS_GUID USBReaderC.obj

I found the lib file that contains the function and manually added it to my list of link directories to search, but that didn't work.

Some other hopefully useful information:

This is intended to be a simple Win32 console application I'm using to debug some things going on at a USB port. I'm running Windows XP SP2, the devel environment is Visual Studio 2005 Pro. I'm using the DEFINE_GUID macro which doesn't seem to be functioning correctly, hence Error 2 above.

Is there something I'm doing wrong in setting up the project

The compile command line:
/Od /D "WIN32" /D "_DEBUG" /D "_CONSOLE" /D "_AFXDLL" /Gm /RTC1 /MDd /Yc"stdafx.h" /Fp"Debug\USBReaderC.pch" /Fo"Debug\\" /Fd"Debug\vc80.pdb" /W3 /nologo /c /ZI /Gz /TP /errorReport:prompt

The link command line:
/VERBOSE /OUT:"H:\Development\Barcode Reader\app\USBReaderC\Debug\USBReaderC.exe" /INCREMENTAL /NOLOGO /LIBPATH:"H:\Program Files\Microsoft Visual Studio 8\VC\PlatformSDK\Lib" /MANIFEST /MANIFESTFILE:"Debug\USBReaderC.exe.intermediate.manifest" /DEBUG /PDB:"h:\Development\Barcode Reader\app\USBReaderC\debug\USBReaderC.pdb" /SUBSYSTEM:CONSOLE /MACHINE:X86 /ERRORREPORT:PROMPT

Thanks in advance for any assistance,

Tom

Visual C++7

I should also mention I have VC 6.0 installed in the same machine. I'm now checking to see if this is affecting me in some obvious way.

You need to add the lib itself (setupapi.lib) to the linker input, not only the directory where it is.

#include <initguid.h> before #include <guiddef.h> in the source code file where you use the DEFINE_GUID macro.

Thanks, Mike!

That fixed the lnk2019 issue!

Onto the lnk2001 issue....

Thanks, nobugz!

That nailed it!
