As described in Readme.md, building 64bit emulator in Windows:
build -p EmulatorPkg\EmulatorPkg.dsc -t VS2013 -a X64

But getting an error linking WinHost:

I tried to checkout different stable edk2 tags like tags/edk2-stable202002 - same issues. I tried building on 3 different machines with different Visual Studios - same problems. Is there any trick building EmulatorPkg?

Found the problem - the build seems to be hardcoded for VS2017. The Winhost makefile in VS2013 build has DLINK_FLAGS that's missing all the necessary libraries. The EmulatorPkg documentation, such as Readme.md, should specify that only specific Visual Studio is supported.

I have been building this recently for a POC showing how we (tianocore) can do Platform CI. As part of that I have enabled the emulatorpkg to use PyTools platform building. This works for VS2017 and VS2019 IA32 and X64. PyTools does all the environment and path management to setup the correct libs, includes, etc.

Help here. https://github.com/spbrogan/edk2/blob/master/EmulatorPkg/README-pytools.md
Server build and execution of emulator shown here. https://dev.azure.com/tianocore/edk2-ci-play/_build/results?buildId=5200&view=results

If that is helpful or you have feedback let me know.

Thanks

Sean, thanks for the quick reply. Which branch/tag are you referring to? I am trying to build from "master" and building with VS2019 is not working. Looking at WinHost.inf, it only mentions VS2015 and VS2017, so VS2019 cannot be supported as checked-in in the master branch.

Also, I really need to use VS2013 as the rest of my environment, including debugger, work in VS2013...

Master of github.com/spbrogan/edk2 should have everything needed.
It is based on master of edk2 from 2 days ago plus changes i have been making to enable platform ci.

I can't help with VS2013. We have focused PyTool efforts on N, and N-1 of VS. So that VS2019 and 2017. Also these two versions are in the new model of having multiple instances of VS so our scheme takes advantage of VSWhere and a more dynamic VS configuration.

See here: https://github.com/spbrogan/edk2/commit/c6d4cda2561a0ec688ac3047611af48f137ec9df or https://github.com/spbrogan/edk2/blob/master/EmulatorPkg/Win/Host/WinHost.inf#L90 to see the addition for VS2019

Thanks
Sean

Thanks Sean, this was very helpful!

To build under VS2013 I had to add these two lines in \EmulatorPkg\Win\Host\WinHost.inf, for IA32 and X64 respectfully:

MSFT:*_VS2013_IA32_DLINK_FLAGS = /LIBPATH:"%VS2013_PREFIX%Lib" /LIBPATH:"%VS2013_PREFIX%VC\Lib" /LIBPATH:"%UniversalCRTSdkDir%lib\%UCRTVersion%\ucrt\x86" /LIBPATH:"%WindowsSdkDir%lib\%WindowsSDKLibVersion%\um\x86" /NOLOGO /SUBSYSTEM:CONSOLE /NODEFAULTLIB /IGNORE:4086 /MAP /OPT:REF /DEBUG /MACHINE:I386 /LTCG Kernel32.lib MSVCRTD.lib Gdi32.lib User32.lib Winmm.lib Advapi32.lib

MSFT:*_VS2013_X64_DLINK_FLAGS = /LIBPATH:"%VS2013_PREFIX%VC\Lib\AMD64" /LIBPATH:"%UniversalCRTSdkDir%lib\%UCRTVersion%\ucrt\x64" /LIBPATH:"%WindowsSdkDir%lib\%WindowsSDKLibVersion%\um\x64" /NOLOGO /SUBSYSTEM:CONSOLE /NODEFAULTLIB /IGNORE:4086 /MAP /OPT:REF /DEBUG /MACHINE:AMD64 /LTCG Kernel32.lib MSVCRTD.lib Gdi32.lib User32.lib Winmm.lib Advapi32.lib

With VS2013 and probably below, it turned out to be very important that an X64 build must start from either "VS2013 x64 Native Tools Command Prompt" or "VS2013 x64 Cross Tools Command Prompt"; an IA32 build would have to start in either "VS2013 x86 Native Tools Command Prompt" or "Developer Command Prompt for VS2013". My build was by default choosing "Developer Command Prompt" and I got build errors.

Hi Sean, does EmulatorPkg support Authenticated UEFI variables? For some reason after initialization mVariableModuleGlobal->VariableGlobal.AuthFormat = FALSE and VariableServiceQueryVariableInfo() returns EFI_UNSUPPORTED. Nt32Pkg used to work well with Authenticated variables, maybe I do not configure EmulatorPkg properly? Thanks!

Eugene,

I actually haven't played with EmulatorPkg until 3 days ago when trying to stand up Platform Ci. I too used the old NT32 environment from time to time but am not well versed in the features of the EmulatorPkg. I found the readme lacking and was able to understand more from looking at the build.sh, buildVs.bat scripts, and DSC/FDF file.
Hopefully someone on the mailing list can help.

Thanks
