Unreal Engine 4 is available for Win10 UWP app dev now

[jsyarrow]

I just pulled the repository and tried to perform a fresh build:

16>Module.ShaderCacheTool.cpp
16>E:\UEUWP\MICROSOFT_UWP_UNREAL\Engine\Source\Programs\Mac\ShaderCacheTool\Private\ShaderCacheTool.cpp(66): error C2039: 'MergeShaderCacheFiles': is not a member of 'FShaderCache'
16>E:\UEUWP\MICROSOFT_UWP_UNREAL\Engine\Source\Runtime\ShaderCore\Public\ShaderCache.h(142): note: see declaration of 'FShaderCache'
16>E:\UEUWP\MICROSOFT_UWP_UNREAL\Engine\Source\Programs\Mac\ShaderCacheTool\Private\ShaderCacheTool.cpp(66): error C3861: 'MergeShaderCacheFiles': identifier not found

Is anyone else encountering this?

Any recommendations is appreciated.

You shouldn't need to build the Mac ShaderCacheTool for Windows platforms. You can safely ignore this error for UWP work.

From the looks of things this problem might also exist in the mainline? Certainly I'm not aware of any changes in this area that are specific to the UWP fork.

Hi,

I'm receiving the following error when trying to compile for the first time in VS2015:

c:\svn\ue4uwp\engine\source\runtime\d3d12rhi\private\D3D12Residency.h(22): fatal error C1083: Cannot open include file: 'dxgi1_6.h': No such file or directory

I'm unable to continue due to this error, has anyone seen this before? I am unable to find any mention of this on the forums or google.

Windows 10 SDK 14393 installed.

I tried installing the latest Win10 SDK but no joy from that either so I uninstalled it.

Thanks,
Jon

We've picked up some changes to the DX12 RHI that rely on newer (post-14393) versions of DXGI. For desktop these are included in the ThirdParty folder, but for UWP we try to get everything from the Windows SDK and 14393 doesn't have what's needed. Later SDKs, however, are not supported with VS2015, which would explain why your attempt to upgrade didn't fix the problem. I only recently became aware of the issue and I'm still thinking about what the best path forward is. In the meantime to workaround your problem you can either upgrade to VS2017 (most future-proof) or else make some engine edits to avoid compiling the D3D12RHI (assuming DX11 only meets your needs).

I'm trying to visit the repo linked in this thread (https://github.com/MICROSOFT-XBOX-AT...OFT_UWP_UNREAL) and I'm getting a 404. It looks like people have visited in the past couple of days. Is it just me?

That was my first thought too. I'm assuming you're not encountering the error.

Ah that explains a lot. Thanks!

Whats the best way to use Xbox Live? Do we implement everything inside C++ with VS from here:
https://docs.microsoft.com/en-us/win...-visual-studio

or do we use built in functionality like the Blueprint node "Show External Login UI"

[jsyarrow]

That was my first thought too. I'm assuming you're not encountering the error.

I actually do see that error if try to build the entire sln. But typically I don't do that - mostly I just build specific pieces relevant to UWP dev (primarily game projects and UAT, with the other necessary bits coming in via the dependency chain).

The fork contains an OnlineSubsystem implementation that targets Xbox Live. While it's not primarily intended for Creators Program titles you should still be able to get some benefit out of it. Make sure to enable the OnlineSubsystemLive plugin for your title, fill in the Xbox Live related fields in the UWP page of Project Settings, and ensure that your app's final identity matches what's shown in Windows Developer Center (you can use the Package/Identity/Name and Package/Identity.Publisher fields in the UWP Project Settings page to control this in a platform-specific way). Once the configuration is done you should be able to use that Show External Login UI node. And if you hit issues there's a fair amount of good info sprinkled around earlier pages of this thread.

Hi jsyarrow,

Thanks for the information before, I'm almost there with a complete compile although I'm now receiving the following error:

cl : Command line error D8004: '/FU' requires an argument

Using the latest Windows 10 SDK. I have both VS2015 and 2017 installed and compiling with either has the same result. What would you suggest?

Thanks,
Jon

I haven't had a chance to try it myself, but you might find the change in this PR helps diagnose the issue.

Make sure to enable the OnlineSubsystemLive plugin for your title:
- To do this I set EnabledByDefault to true for \Engine\Plugins\Online\OnlineSubsystemLive\OnlineSubsystemLive.uplugin
- I added OnlineSubsystemLive to PublicDependencyModuleNames for my project, inside Project.Build.cs file
- Finally I added the following to my project's DefaultEngine.ini

[OnlineSubsystem]
DefaultPlatformService=OnlineSubsystemLive

Once I build my project I get a bunch warning and errors, please see attached image. Any ideas?

If I remove the dependency to OnlineSubsystemLive inside my build.cs file it compiles just fine.

Ok, this was caused by a typo in the generated command line options for me.

The end of the build command looked like this "-waitmutex-2017", instead of "-waitmutex -2017". I've been compiling with a custom script since then, but I believe one of the recent commits fixes this issue.

The one crazy caveat, though, is that you must delete Intermediate and Saved before attempting to build again!

Those errors look like you're building OnlineSubsystemLive for an Editor configuration. To avoid this, you should remove the reference from your build.cs and instead enable the plugin by listing it in the plugin collection in your uproject. That should make sure it's only on for the proper platforms and configurations.
