Hello Thomas,
Many thanks for your advise. I have changed my active_platform to
Nt32Pkg/Nt32Pkg.dsc but I still get the exact same error as before.
I used the 32bit command prompt from vs studio 2013.
Thanks.

Subject: Re: [edk2] edk2 build problems
The UEFI shell is an application that can be run in a UEFI environment (either
on real or emulated hardware) similar to how the Windows command prompt runs in
the Windows OS. So first you need to have a UEFI environment. There are many
options here. There is a UEFI environment on your computer before the Windows
OS loads, so you can build and .efi file from ShellPkg or get the pre-built one
from ShellBinPkg and put it on a USB and boot to it from your boot manager. You
can also build an emulated (Nt32Pkg) or virtual (OVMF) UEFI environment from
edk2.
The simplest route for you is probably to build Nt32Pkg. It creates the
emulated UEFI environment and also builds the shell application for you and
starts it by default. There used to be really simple instructions on tianocore,
but things have gotten moved around a lot. Pretty much you just build Nt32Pkg
(32-bit, of course) and it produces and .exe deep in the Build folder. You run
the .exe and it brings up the emulated environment and starts the shell
application. If my memory is correct, you just need to change your
TOOL_CHAIN_TAG to VS2013x86, and in edk2 folder from the command line run
"edksetup.bat --nt32" to set up your build environment, then "build" to
actually build Nt32Pkg, then "build run" to run the .exe that is produced.
Btw, MdeModulePkg is just a collection of drivers and libraries, it is not a
full firmware. Packages like OvmfPkg and Nt32Pkg (ones containing a .fdf) pull
things together into a complete firmware. For real hardware, people create
their own packages (not included in edk2, of course) that pull things together
with platform specific code.

I am very new to uefi dev and trying to understand how the environment needs to
be setup to bring up the uefi shell.
My current environment is:win 7 pro 64bitvs studio express 2013 for desktopedk2
The edk2 binaries are in the f:\ folder. I have modified target_arch &
toolchain to reflect my build platforms. That said I have tried x64 as my
target_arch too.
I like to think that I have set up the environment correctly (after ironing
other errors) but when I do a build from vs2013 command line (and also from x64
command line) I get the following error for which I cannot seem to find a
resolution:

I read somewhere that the winsdk needs to change from the default v6.0a to one
that suits your vs studio. I changed that to v8.0a to no effect.
Following the guide from edk2 I set my active_platform to be
MdeModulePkg/MdeModulePkg.dsc. I have seen other people using Nt32Pkg. I have
tried that as well. What is the difference and why must we chose one over the
other.
I will appreciate your assistance.
Thanks,Tony
