Re: Building EmulatorPkg and EDK2 project issue.

[Prem Kumar <perry.prem@gmail.com>]

Hi Andrew,
 Thanks for your explanation.

After building for x64 I could see below error.

C:\UEFIWorkspace\edk2-master_2018_Latest\Build\EmulatorX64\DEBUG_VS2015x86\X64>WinHost.exe

EDK II WIN Host Emulation Environment from http://www.tianocore.org/edk2/
  BootMode 0x00
  OS Emulator passing in 128 KB of temp RAM at 0x65e70000 to SEC
ERROR : Can not open Firmware Device File ../FV/FV_RECOVERY.fd (0xE).
Exiting.


*I've searched for FV_RECOVERY.fd in entire project and found no such file
generated after built.*

Thanks & Regards,
Prem.
