David,
Yes. You can directly use libraries from a UEFI Application. There is an
example Hello World UEFI Application in the MdeModulePkg that can be built for
all supported CPU architectures and it also demonstrates use of libraries from
the MdePkg and MdeModulePkg. The path is:
MdeModulePkg\Application\HelloWorld\HelloWorld.inf
To build just this one UEFI application for X64 from the command line using
VS2008:
Ø build -a X64 -t VS2008x86 -p MdeModulePkg\MdeModulePkg.dsc -m
MdeModulePkg\Application\HelloWorld\HelloWorld.inf
You can create your own package with your own UEFI applications following the
HelloWorld example in the MdeModulePkg.
The UEFI Driver Wizard found at the following link also provides easy ways to
create new EDK II packages and add new UEFI drivers to a new package. You
could use that tool to get started and then populate your own UEFI Applications
into your own package.

Subject: [edk2] help getting started creating efi x64 application using package
system
Hi,
So as a test I was able to create a x64 EFI application using VS2008 command
line by using some of the header files under mdepkg\include and
mdepkg\include\X64 along with then genfw to convert the .dll to the .efi. This
worked fine. But, I'm thinking it would be nice to use some of the existing
libraries (especially to handle malloc/free, new/delete, open/close etc..) and
not have to rebuild the wheel so to speak. The question is, would I need to
figure out and use this "package" system with all its GUID's and defines, etc..
or can I just link to existing libraries? I wouldn't mind using the package
system if it made since to me. Could someone indicate where/how you would add
a general efi application, using the package system, that won't be in firmware
or part of any package. It will be a stand alone app that can be run on any
(x64 - Intel/AMD based) UEFI system.
Thanks!!
