Runtime NoExportTypes error count exceeds 100; stoppig compilation

iam_Raavanan · March 29, 2021, 6:16am

Hi,

I was using UE4 4.24 and building the project, and it was working fine. Recently, I made some changes by integrating 3rd party SDK. And I was getting this error on building project.

Even, I removed all the changes I made for integrating the 3rd party SDK. But, it still stops me in the following erros.

If anyone aware/familiar with this issues, Kindly, help me out!

Errors:

I have followed up the 4.24 transition guide, it helps me to solve the above issue. if anyone facing similar issue, follow this link

open your YourProjectEditor.Target.cs file and include this line
DefaultBuildSettings = BuildSettingsVersion.V2;

// Copyright 1998-2019 Epic Games, Inc. All Rights Reserved.

using UnrealBuildTool;
using System.Collections.Generic;

public class YourProjectEditorTarget : TargetRules
{
    public YourProjectEditorTarget( TargetInfo Target) : base(Target)
    {
        Type = TargetType.Editor;
        DefaultBuildSettings = BuildSettingsVersion.V2;
 
        ExtraModuleNames.AddRange( new string[] { "YourProject" } );
    }
}

By, including this line in to Editor.Target.cs, it demands all the includes and fix all the paths by adding the subfolders.
