Hi all,

I am trying to package my game but I am getting build errors. I am adding a snippet of the output log here :

How come the engine fails to compile here ?

Many thanks.

Cheers,

I haven’t tried it again yet… Will give it some time soon. I gave up on it until I find some new information on it.

Hey DarkZ,

Could you get it to work?

This situation takes place, if you add UnrealEd to your *.Build.cs and build the project with the configurations without the editor (f.e. “Development” instead of “Developnment Editor”). Macro WITH_EDITOR = 0 with such configurations. Look at UnrealEd.h. When WITH_EDITOR == 0, the part of the file with many #include doesn’t get into the build. Thus, the first error “missing ‘;’ before identifier ‘EditorInit’” occurs. The type int32 is unknown as it is defined in the header file which doesn’t get into the build because of the macro. Other errors happen according to the same scenario.

5

Ah that seems like a great answer. I will try it out and get back to you. Thanks !

6

Would I define WITH_EDITOR in my Game.h file ?

7

I think this is not a corrent decision. WITH_EDITOR is defined by UBT. Look at …\Engine\Source\Programs\UnrealBuildTool\Configuration\UEBuildTarget.cs. I also think that you don’t need UnrealEd for configurations without the editor. It doesn’t make any sense. Add it optionally in your *.Build.cs for configurations with the editor

8

I checked and I don’t have UnrealEd in my build.cs. file So I think the issue is also that I need to build my project in Development mode. Howevever I get the following error as its not able to find the symbol UNREALED_API

1> Module.Engine.16_of_41.cpp
1>C:\User\study\animation\code\UnrealEngine4.2\Engine\Source\Editor\UnrealEd\Public\UnrealEd.h(54): error C2146: syntax error : missing ‘;’ before identifier ‘EditorInit’

It seems that a certain file includes UnrealEd.h. The scenario with WITH_EDITOR == 0 happens for configurations without the editor. That is why such things as UNREALED_API, int32 etc are not defined.

public TaskBasedLM(TargetInfo Target)
{

        MinFilesUsingPrecompiledHeaderOverride = 1;
        bFasterWithoutUnity = true;

		PublicDependencyModuleNames.AddRange(new string[] { 
            "Core", 
            "CoreUObject",

          //  "EditorStyle",

            "InputCore",

            "AnimGraph" });

        PrivateDependencyModuleNames.AddRange(new string[] { 
        //        "PropertyEditor"
        });
        
        PrivateIncludePathModuleNames.AddRange(
            new string[] {

          //  "EditorStyle"

        );

            new string[] {

        );

		bFasterWithoutUnity = true;

		// {
		//		if (UEBuildConfiguration.bCompileSteamOSS == true)
		//		{
		//			DynamicallyLoadedModuleNames.Add("OnlineSubsystemSteam");
		//		}
		// }

        LoadANNLibrary(Target);
	}

This is what my build.cs. looks like. I have commented a bunch of modules with the hope to find the one which is including UnrealEd.h My project does not include UnrealEd.h anywhere though

11

I have discovered that a precompiled header for UnrealEd comes into play as soon as I include AnimGraph module … And then I get a bunch of errors. AnimGraph depends on UnrealEd, so that explains it. However I need AnimGraph as I implement a custom AnimGraphNode in my project.

I wonder if its possible to exclude certain classes depending on the build type because there’s really no need to build an AnimGraphNode for a packaged project.

You need to make another module. Look at answer:

This fixed all my problems. I can now compile to both the editor target and package my game as well. I had to cook my content through the editor first. Today I learnt a lot of new things about the build setup. Thanks for your time and patience.
