Build UEFI Application --- ShellCEntryLib.h + ShellAppMain (EFI Library build)

建立UEFI的Application步驟，可參考如下。
將C:\EDK2\MdeModulePkg\Application中HelloWorld整個folder複製到C:\EDK2\MyPkg\Application中改名Hello，接下來修改一些地方
 1.1 MyPkg\Application\Hello\Hello.inf
=============================================================
[Defines]
  #為避免衝突而改
  INF_VERSION         = 0x00010006
  #產生文件名字為 Hello.efi
  BASE_NAME             = hello
  #(避免 GUID 與其他文件衝突，至 Create GUIDs online 產生新的一組GUID，或開啟VS2010 -> Tools -> Create GUID 來產生GUID)
  FILE_GUID            = ab0f9969-0a54-4695-ace7-42fe6bb84a1d  
  #模型種類：UEFI_DRIVER, DXE_DRIVER, DXE_RUNTIME_DRIVER, UEFI_APPLICATION, BASE等
  MODULE_TYPE     = UEFI_APPLICATION
  #可自行修改
  VERSION_STRING = 1.0
  #入口函數
  ENTRY_POINT          = ShellCEntryLib

#
#  VALID_ARCHITECTURES           = IA32 X64 IPF EBC
#
#主要的編譯文件
[Sources]
  Hello.c
# .dec裡面定義include的路徑
[Packages]
  MdePkg/MdePkg.dec
  ShellPkg/ShellPkg.dec
#連結的函數庫
[LibraryClasses]
  ShellCEntryLib
  UefiLib
=============================================================


 1.2 增加入口函數到Nt32Pkg\Nt32Pkg.dsc，注意紅色字所添加的位置
=============================================================
[LibraryClasses]
  #
  # Entry point
  #
…
UefiApplicationEntryPoint|MdePkg/Library/UefiApplicationEntryPoint/UefiApplicationEntryPoint.inf
ShellCEntryLib|ShellPkg/Library/UefiShellCEntryLib/UefiShellCEntryLib.inf
============================================================= 


1.3 Hello.inf 添加到 Nt32Pkg.dsc 或UnixPkg.dsc 的[Components.IA32]部分
=============================================================
[Components.IA32]
…
  MdeModulePkg/Application/HelloWorld/HelloWorld.inf
  MyPkg/Application/Hello/Hello.inf


1.4 Hello.c
#include <Uefi.h>
#include <Library/UefiLib.h>

INTN EFIAPI
ShellAppMain (
  IN UINTN Argc,
  IN CHAR16 **Argv
  )
{
  Print(L"Hello !Welcome to the world of EDK II.\n"); //注意’P’大寫
  return(0);
}

1.5 再一次執行以下三行指令即可 
        (1) build cleanall
        (2) build
        (3) build run

1.6 在Shell中輸入 hello
