Summary

I’m getting the following errors when attempting to build 5.6.0 from source code:

Error C1083 Cannot open include file: '../Plugins/Developer/Concert/ConcertApp/MultiUserClient/Source/MultiUserClient/Private/Widgets/ActiveSession/Replication/Client/Multi/Columns/AssignedClients/MultiStreamColumns_AssignedClients.cpp': No such file or directory

Error C1083 Cannot open compiler generated file: '..\Plugins\VirtualProduction\CaptureManager\CaptureManagerEditor\Intermediate\Build\Win64\x64\UnrealEditor\Development\CaptureManagerEditorSettings\Module.CaptureManagerEditorSettings.cpp.dep.json': No such file or directory

UI/Tools

Steps to Reproduce

  1. Download and install VS 2022 and the required components as outlined here:
    https://docs.unrealengine.com/en-US/setting-up-visual-studio-development-environment-for-cplusplus-projects-in-unreal-engine/
  2. Download the source code zip for UE-release-5.6.0 and unzip
  3. Run the setup.bat
  4. Run the GenerateProjectFiles.bat
  5. Open the solution in VS, set the solution configuration and platform to Development Editor - Win64
  6. Attempt to build the UE5 target

Expected Result

Successful compilation of target

Observed Result

Error C1083 Cannot open include file: '../Plugins/Developer/Concert/ConcertApp/MultiUserClient/Source/MultiUserClient/Private/Widgets/ActiveSession/Replication/Client/Multi/Columns/AssignedClients/MultiStreamColumns_AssignedClients.cpp': No such file or directory

Error C1083 Cannot open compiler generated file: '..\Plugins\VirtualProduction\CaptureManager\CaptureManagerEditor\Intermediate\Build\Win64\x64\UnrealEditor\Development\CaptureManagerEditorSettings\Module.CaptureManagerEditorSettings.cpp.dep.json': No such file or directory

Platform(s)

Win64

Additional Notes

I can also confirm that the Module.CaptureManagerEditorSettings.cpp.dep.json file is in fact missing from the downloaded source code. MultiStreamColumns_AssignedClients.cpp however, is present at the cited location.

hi @sammichael25
Here is quote from my forked repository for 5.6
Using GitHub means you can check the status of files with

git status

$ cd ue5Lgpu56

$ setup.bat

$ GenerateProjectFiles.bat -2022

$ REM make changes so the file looks like below

$ notepad Engine\Saved\UnrealBuildTool\BuildConfiguration.xml


<?xml version="1.0" encoding="utf-8" ?>
<Configuration xmlns="https://www.unrealengine.com/BuildConfiguration">
   <!-- This file must be copied into Engine\Saved\UnrealBuildTool\\BuildConfiguration.xml -->
   <!-- see https://docs.unrealengine.com/5.2/en-US/build-configuration-for-unreal-engine/ -->
   <ProjectFileGenerator>
     <Format>VisualStudio2022</Format>
   </ProjectFileGenerator>
   <BuildConfiguration>
   <!-- This will stop generation OF 48GB PDB debug files NOT needed in LGPU 5.4-->
   <bUsePDBFiles>false</bUsePDBFiles>
   <bOmitPCDebugInfoInDevelopment>true</bOmitPCDebugInfoInDevelopment> 
   <bDisableDebugInfoForGeneratedCode>true</bDisableDebugInfoForGeneratedCode>
   </BuildConfiguration>

</Configuration>

Right-click UE5.sln and select “Open With” → “Microsoft Visual Studio 2022”

When the Repository has opened in VS 2022. Right Click UE5 and select “Set As Startup Project”

Set your solution configuration to Development Editor and your solution platform to Win64,

then right click the UE5 target and select Build.
