Hi All, I am a newbie in EFI. I have the following problem.

I created my own package with my own test application (to understand EFI
environment).

Here is code in *MyPkg.dsc:*

[Defines]
PLATFORM_NAME = MyPkg
PLATFORM_GUID = 22F5F173-EB34-43CA-AD34-2E82DE15E288
 PLATFORM_VERSION = 0.10
DSC_SPECIFICATION = 0x00010005
OUTPUT_DIRECTORY = Build/MyPkg
 SUPPORTED_ARCHITECTURES = IA32|X64
BUILD_TARGETS = DEBUG|RELEASE
SKUID_IDENTIFIER = DEFAULT

*MyPkg.dec:*

[Defines]
  DEC_SPECIFICATION              = 0x00010005
  PACKAGE_NAME                   = MyPkg
  PACKAGE_GUID                   = 04106E18-1418-46A9-82A1-E28E0C46D02E

VERSION_STRING = 0.1 ENTRY_POINT = MyAppEntryPoint [Sources] MyApp.c
[Packages] MdePkg/MdePkg.dec [LibraryClasses] UefiApplicationEntryPoint

*MyApp.c:*

#include <Uefi.h>
#include <UefiLib.h>

EFI_STATUS
EFIAPI
SMBIOS_TABLE_ENTRY_POINT *mSmbiosTable = NULL;

MyAppEntryPoint (
IN EFI_HANDLE ImageHandle,
IN EFI_SYSTEM_TABLE *SystemTable
)
{
EfiGetSystemConfigurationTable (&gEfiSmbiosTableGuid,
(VOID**)&mSmbiosTable);
 return EFI_SUCCESS;
}

I trying to get SM Bios EntryPoint informations, but when I run "build" I
have error:
 "Cannot  open include file:  `UefiLib.h` : no such file or directory".
I wanna use function:
"EfiGetSystemConfigurationTable" from
"\EDKII\MdePkg\Library\UefiLib\UefiLib.c"

How and where I must include this to good work with that?

Please help me with that problem to understand the EFI environment
and allow me to use other functions of EDK2.
