RE: [ntdev] RE: [ntdev] LNK2001 error unresolved external symbol

I built my driver using Visual Studio 2008 without any problems. The IntelliSense feature is very handy to develop with. We had Jerry Lozano come on-site to work here (he?s the author of a Windows device driver book) to give a class. He had a wizard that could plug in to Visual Studio that sets it up for building drivers.

And just how are you building things? Are you using the Visual Studio IDE, building it just like you would an application? If so, you are wrong. You need to open a sanctioned WDK build environment and either run BLD or BUILD. BLD is a macro wrapping BUILD so you will still run build. Using BUILD, unmodified Toaster source files and SOURCES will build a SYS file.

An alternative is to download DDKBUILD.bat from either OsrOnline or Hollistech.com, and create a makefile project in VS.

Hi!
I'm new to driverprogramming.
I'm using Visual Studio 2008 with the VisualDDK Extension.
WDK,installed is WDK 7600.16385.0.
OS is Windows 7 Professional

I decided to start off using the simple Toaster example shipped with the WDK-installation.
(I got this ideal from reading a Paper)
I wrote the code while reading it.
I sort of need a working example,I can edit, before i start digging deeper and try to understand it a little bit more.
Problem is that I get the following errors(1 beeing caused by it's precessors),which I can't resolve.

Fehler 1 error LNK2001: unresolved external symbol _WdfFunctions toaster.obj Toaster
Fehler 2 error LNK2001: unresolved external symbol _WdfDriverGlobals toaster.obj Toaster
Fehler 3 fatal error LNK1120: 2 unresolved externals e:\windriver\toaster\toaster\objchk_win7_x86\i386\Toaster.sys Toaster

I appended the sourcecode as Zipfile.
I hope someone can tell me what isn't working and why.

I really am eager to learn but every theory is grey without practice, so I need this to pick it up from here.
sincerly

Thomas

Module Name:

Toaster.c

Abstract:

This is a simple form of function driver for toaster device. The driver
doesn't handle any PnP and Power events because the framework provides
default behavior for those events. This driver has enough support to
allow an user application (toast/notify.exe) to open the device
interface registered by the driver and send read, write or ioctl requests.
