Help to Build a Plugin for Unreal 5.3 and Unreal 5.4

[NISP2709]

When I am trying to open the project the Unreal Projects states that to build the plugin manually, So I am writing the command to build it for both the engine version. For the Both the Engine I getting different errors. This are the following commands and errors that I am getting while building the plugin:

I am not much of a programmer, Please guide if I am making some mistakes.

Please Let m know where I am making mistake

[bcoconni]

It has been mentioned in #1051 that the JSBSim plugin is compatible with UE 5.0-5.3. Note sure about 5.4. @gallonmate, any idea ?

[bcoconni]

@NISP2709, it is mentioned in the error report that you have posted that more details are available in logs:
UnrealBuildTool failed. See log for more details. (C:\Users\DigiCon\AppData\Roaming\Unreal Engine\AutomationTool\Logs\C+Program+Files+Epic+Games+UE_5.3\UBT-UnrealEditor-Win64-Development.txt)
and
UnrealBuildTool failed. See log for more details. (C:\Users\DigiCon\AppData\Roaming\Unreal Engine\AutomationTool\Logs\C+Program+Files+Epic+Games+UE_5.4\UBA-UnrealEditor-Win64-Development.txt)

Would you mind posting the content of these logs ?

[NISP2709]

Here are the log files for both the version that is generated.

Thanks.

UBT-UnrealEditor-Win64-Development_5.3.txt

Did you already follow all the steps in the Read Me file? https://github.com/JSBSim-Team/jsbsim/blob/master/UnrealEngine/README.md

Basically:
First open JSBSimForUnreal.sln and build it in Visual Studio.
Then you can right click on UnrealEngine\UEReferenceApp.uproject and select "Generate Visual Studio project files". After some time the file UEReferenceApp.sln will appear beside the uproject file. Open it and build it in Visual Studio. Try these steps with UE5.3 first.

[tbuckup]

I confirm it cant build in 5.5.
Two things need to be fixed:

• First the toolchain needs to be the 14.38.33130, since 14.29 is not supported anymore. Instructions in https://github.com/JSBSim-Team/jsbsim/tree/master/UnrealEngine are not correct anymore.

• Second, one needs to edit the UEReferenceAppEditor.Target.cs as :

 DefaultBuildSettings = BuildSettingsVersion.V5;
 CppStandard = CppStandardVersion.Cpp20;
 IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_5;
 BuildEnvironment = TargetBuildEnvironment.Shared;

[gallonmate]

Thanks. I also finally got around to testing UE5.4 and can confirm it's a similar issue. I will submit a pull request for these changes and to update the instructions found in the Readme file.

[adl67]

Thank you a lot! It works without any modify in UE5.4 but it don't works with 5.5 for me, in UE5.5 I have the error "exit from comand ""C:\Program Files\Epic Games\UE_5.5\Engine\Build\BatchFiles\Build.bat" UEReferenceAppEditor Win64 Development -Project="E:\Lavori\Unreal\jsbsim5.5\UnrealEngine\UEReferenceApp.uproject" -WaitMutex -FromMsBuild -architecture=x64" with code 6."

[gallonmate]

@adl67 can you post more of the log file or check it for other errors/messages? One common thing you can do is run the "CleanProject.bat", found in your project "jsbsim\UnrealEngine" folder, which will cleanup the build files, then you can generate VS solution, and try building the plugin.

[adl67]

Thank you Gallonmate, but I have the same error for UE 5.5 after clean.bat too with or without any modifies in the Source, this is the log and thank you for any help...
