Getting unreal.hx to work with UE 4.22

[mfoda]

Hi. I tried compiling the plugin in an empty 4.22 project but got two errors in UnrealHx/Source/HaxeInit/BuildApi.Build.cs due to API changes in 4.22, which required changing these two lines:

// line 204
BuildVersion version = BuildVersion.ReadDefault();
// changed to -->
ReadOnlyBuildVersion version = ReadOnlyBuildVersion.Current;

//...

// line 347
foreach (FileReference ProjectFile in UProjectInfo.AllProjectFiles)
// changed to -->
foreach (FileReference ProjectFile in UnrealBuildTool.NativeProjects.EnumerateProjectFiles())
//

After that, I tried compiling but got EXEC : error : Build failed: Cannot find property PluginDir

Any ideas what's causing this or how I can get more debug info to troubleshoot? I'm not sure how to trace it back to the specific file/function where this is happening. Here's the full build output (using vs2017, latest (development) unreal.hx, haxe 3.4.7, and UE-4.22).

Any help would be appreciated!

It seems to be support for 4.22 in the development branch now, and generated externs also exist. But im getting the same issue even with the latest commits too. Maybe @waneck is still working on the 4.22 support and its not ready yet?

[datee]

Actually i was mistaken - the current error seems to be:

Lets hope for a fix to this :)

Same issue here, still no news on 4.22 support??

[StatiS]

I also get the same error trying to compile with ue4 4.21.2... Also tried with older versions of hxcpp with same results.

@datee Are you able to build succesfully on any ue version currently? I can't.

[waneck]

Hey guys! Could you please test now? I just submitted a fix, https://github.com/proletariatgames/unreal.hx/commit/f3a097e27e16ea6f6004ca87dc746e818a7be5dd , which I believe should fix it

[datee]

Hi!

I gave it a quick try with the latest commit - clean c++ 4.22 project from the epic launcher, windows 10, Haxe 4 rc2.

Same error:

Tried it more on several computers - all still with the same issue .. UnrealBuildTool gives errors with 4.22. (Works fine on 4.21 though)

[waneck]

Thanks for trying it! Could you give me more information on what error do you see? I believe that Build failed: Cannot find property ProjectFile should be fixed now

[StatiS]

Trying things out at the moment, attempting to build on a fresh c++ 4.22.3 project, with the latest commits, still gives the same error for me as well:

Before these latest commits, I was getting the same error even when using version 4.21.2, but with the latest commits, I don't anymore.

Also Im using win10, Haxe 4 rc2, hxcpp 4.0.8

[datee]

Yup, same here. I guess the "Build failed: Cannot find property ProjectFile" error is still present even after the fix then.

[waneck]

Sorry guys, I realized that our perforce automatic syncs isn't working so that's why the change isn't in the git repo. I'm looking into solving this ASAP and I'll let you know as soon as I do

Great!! Now its working to compile and start a 4.22 project!

Some things i noticed in testing:

The initial build fails: 1>Building 4 actions with 16 processes... 1> [1/4] Unreal.Win-Dev-Editor.uhxglue.cpp 1>D:/work/unreal/projects/HX4_test4/Intermediate/Haxe/HX4_test4-Win-Development-Editor/Generated/Private/uhx/glues/FTextImpl_Glue.cpp(40): error C2039: 'AsHourMinuteTimespan': is not a member of 'FText' 1> c:\unrealengine\engines\ue_4.22\engine\source\runtime\core\public\Internationalization/Text.h(325): note: see declaration of 'FText' 1>D:/work/unreal/projects/HX4_test4/Intermediate/Haxe/HX4_test4-Win-Development-Editor/Generated/Private/uhx/glues/FTextImpl_Glue.cpp(40): error C2664: 'unreal::VariantPtr uhx::glues::FTextImpl_Glue_obj::AsHourMinuteTimespan(unreal::VariantPtr,unreal::VariantPtr)': cannot convert argument 1 from 'T' to 'unreal::VariantPtr' 1> with 1> [ 1> T=FTimespan 1> ] 1> D:/work/unreal/projects/HX4_test4/Intermediate/Haxe/HX4_test4-Win-Development-Editor/Generated/Private/uhx/glues/FTextImpl_Glue.cpp(40): note: No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called 1>C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\VC\VCTargets\Microsoft.MakeFile.Targets(44,5): error MSB3075: The command "C:\UnrealEngine\Engines\UE_4.22\Engine\Build\BatchFiles\Build.bat HX4_test4Editor Win64 Development -Project="D:\work\unreal\projects\HX4_test4\HX4_test4.uproject" -WaitMutex -FromMsBuild" exited with code 5.

Removing AsHourMinuteTimespan from FText_Impl and FText fixes the problem and the project compiles. Are you getting the same error?

And.. ... I get this warning always when compiling .. however the project does compile and run... What is the reason for this? This was also present before the fix.

[StatiS]

Thanks for the fix waneck! 😄

Also, seconding datee here, I ran into the same issue with AsHourMinuteTimespan and am getting the same UnrealBuildTool warning.

[datee]

Should this issue be re-opened? As is now the 4.22 build is failing with a standard project without fixing it... I can do a pull request with the fixes maybe

[waneck]

Sure. Sorry about that. I'll prioritize the issues here to look into them later this week
