Can't build Unreal Editor 4.27.2 from source

Gil · September 23, 2022, 2:54pm

Hi everyone,

I’m having a hard time building the engine from source consistently. Sometimes it works sometimes it doesn’t. I tried here to do a fresh build and I’m stuck with errors.

Severity	Code	Description	Project	File	Line
Error	C4668	‘_NOEXCEPT_TYPES_SUPPORTED’ is not defined as a preprocessor macro, replacing with ‘0’ for ‘#if/#elif’	UE4	C:\Program Files (x86)\Windows Kits\10\include\10.0.22621.0\winrt\wrl\event.h	211

Error	C4668	‘__cpp_noexcept_function_type’ is not defined as a preprocessor macro, replacing with ‘0’ for ‘#if/#elif’	UE4	C:\Program Files (x86)\Windows Kits\10\include\10.0.22621.0\winrt\wrl\event.h	371
Error	MSB3073	The command …..\Build\BatchFiles\Build.bat -Target=UE4Editor Win64 Development -Target=ShaderCompileWorker Win64 Development -Quiet -WaitMutex -FromMsBuild exited with code 6.	UE4	C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Microsoft\VC\v160\Microsoft.MakeFile.Targets	45

To reproduce here are the step I do:
Clone UE
git clone -b 4.27.2-release https://github.com/EpicGames/UnrealEngine.git 4.27.2-release
Launch Setup.bat, GenerateProjectFiles.bat
Open UE4.sln → Setup Development Editor & Win64 → right click on UE4 → Build

I use Visual Studio Community 2019, version 16.11.19
In the Tools & Features I have selected .NET desktop, C++ desktop, Unity video game & C++ games development (the names might differentiate but you get the idea)

Here is the log of the build

Any idea what I’m missing ? Is there something that should be installed on the computer ?

MoeinShams_CGI · October 4, 2022, 3:02am

I get the exact same set of errors.

I downloaded https://github.com/ufna/UnrealEngine/tree/4.27-html5_dev from github which is a version of ue 4.27 including HTML export, my visual studio is 2022 as I use windows 11, and when I open the sln file with visual studio 2017, or 2019 the target is marked as “incompatible”.

I really need to get this version compiled as I have an important project to do with HTML, but no hope yet.

Would really appreciate if someone shows up and offers something.

I think I tried to compile Unreal 4.27.x with VS2022 and it did fail too. Have you tried with VS2019 ?

BoBoMX · October 11, 2022, 5:47am

Have you try these SDK?

and also these

By the way, I use VisualStudioCommunity 2019.
The pictures are capture from VisualStudioInstaller for 2019.

Gil · October 11, 2022, 7:39am

Here it’s what I have installed on my part (sorry the list is in french)

I will add Windows 10 SDK (10.0.18362.0) but I think I had read that 10.0.19 was mandatory. We will see.

jackiex9527 · November 9, 2022, 5:40am

I got exactly same issue, the visual studio are using window 10 sdk 10.0.22, which is not support by visual studio 2019. So, there is a way to configure visual studio to use different version of window 10 sdk.

A evidence for this is you can’t isntall window10 sdk 10.0.22 in the visual studio 2019 installer

Edited: 10.0.22 is actually window 11 sdk, so that may cause the error

Worked for me with 4.27 and VS2022. Got it compiled and it’s running all as intended.

traditore · November 18, 2022, 6:15pm

Use Windows 10 SDK(10.0.18362.0) and Unload Windows 11 SDK
Reset computer
delete Engine\Intermediate\Build\Win64\UE4Editor\Development\VisualStudioDTE” folder
run Setup.bat and GenerateProjectFiles.bat
open .sln and build ue4

Heerbann · November 20, 2022, 9:15am

I can confirm this works. make sure that the proper sdk version is installed. and maybe it should be the only one present.

Gil · November 21, 2022, 6:51am

Hey everyone, I’m glad it should be working but I’m still stuck. I have removed all SDK except 10.0.18362.0 and I’m still using VS2019.
I tried also to compile it in a high root folder like C:\UE\ to avoid long path errors on Windows.
These are the selected packages that I have now

Since last time I created a Jenkins pipeline so I can test it from scratch easily.
Here is the output log from the last failed build (with the last steps). Sorry it is in french, it should be in english next time.

Gil · November 24, 2022, 3:40pm

Well I just made it working.
By reading other posts from here I have removed .NET Core 3.1 and installed specifically .NET 4.5 (aim pack ? somthing like that and not 4.5.1 or 4.5.2)
The compilation from the editor worked after that.

I did not test my jenkins script yet.

I added bEnableUndefinedIdentifierWarnings = false at the end of the HoloLensTargetPlatform.Build.cs file, and the compilation passed~

livada · January 17, 2023, 1:25pm

Had the same error/warning with VSC2022 and disabling warnings in Build.cs solved the issue.

Ohms-Qstudios · March 1, 2023, 8:30am

This works for me.

Ariel_Gimenez · March 27, 2023, 4:42pm

Here they explain it very well, you have to install visual studio 2017 with the things mentioned and compile with visual studio 2022.

MrStreakman · March 27, 2024, 5:54am

This works for me as well, but why does anyone know why adding this to the HoloLensTargetPlatform in particular works?
