Hi all, I compiled Vlv2TbltDevicePkg and operated according to the following URL: https://github.com/tianocore/edk2-platforms/tree/master/Platform/Intel/Vlv2TbltDevicePkg The compiled command is as follows: build -a IA32 -a X64 -n 5 -t VS2019 -b DEBUG -p Vlv2TbltDevicePkg\PlatformPkgX64.dsc The result is the following error message: edk2p\Build\Vlv2TbltDevicePkgX64\DEBUG_VS2010x86\X64\MdePkg\Library\BaseLib\BaseLib\OUTPUT\X64\DisablePaging64.iii:35: error: symbol `InternalX86DisablePaging64.0' undefined NMAKE : fatal error U1077: 'c:\nasm\nasm.EXE' : return code '0x1' My version of Nasm is nasm-2.13.03, how can I solve the error about nasm? Any suggestion is greatly appreciated! Thanks!
