UE4 报错 missing type specifier - int assumed

没有提示的错误，但是编译时就出现：missing type specifier - int assumed

我出现的原因是在使用MergeActor时，

#include "Editor/MergeActors/Public/IMergeActorsModule.h"

当在其他文档引用时，build的时候，就提示 MergeActorsModule.h文件中很多错误，就包括missing type specifier - int assumed。

解决办法：

MergeActors是一个单独的Module，在其他Module中使用时，添加头文件后，要在Build.cs文件中添加相应Module，才会正常，如我在ContentBrowser.Build.cs中添加，如下：

// Copyright 1998-2018 Epic Games, Inc. All Rights Reserved.
    
    using UnrealBuildTool;
    
    public class ContentBrowser : ModuleRules
    {
    	public ContentBrowser(ReadOnlyTargetRules Target) : base(Target)
    	{
    		PrivateIncludePathModuleNames.AddRange(
    			new string[] {
    				"AssetRegistry",
    				"AssetTools",
    				"CollectionManager",
    				"EditorWidgets",
    				"GameProjectGeneration",
                    "MainFrame",
    				"PackagesDialog",
    				"SourceControl",
    				"SourceControlWindows",
                    "MergeActors"
                }
    		);
    
    		PrivateDependencyModuleNames.AddRange(
    			new string[] {
                    "AppFramework",
    				"Core",
    				"CoreUObject",
    				"ApplicationCore",
                    "InputCore",
    				"Engine",
    				"Slate",
    				"SlateCore",
                    "EditorStyle",
    				"SourceControl",
    				"SourceControlWindows",
    				"WorkspaceMenuStructure",
    				"UnrealEd",
    				"EditorWidgets",
    				"Projects",
    				"AddContentDialog",
    				"DesktopPlatform",
    				"XmlParser",
    			}
    		);
    
    		DynamicallyLoadedModuleNames.AddRange(
    			new string[] {
    				"PropertyEditor",
    				"PackagesDialog",
    				"AssetRegistry",
    				"AssetTools",
    				"CollectionManager",
    				"GameProjectGeneration",
                    "MainFrame",
                    "MergeActors"
                }
    		);
    		
    		PublicIncludePathModuleNames.AddRange(
                new string[] {                
                    "IntroTutorials"
                }
            );
    	}
    }

之后就正常了。
