Iirc you need to modify your msvc installation, check this for details:

4

Whenever I get exit-code 6 I save in Unreal, close, and try to recompile in VS. It seems to be something with live-coding or having both apps open?

I cannot say I ever saw issues with some-kind-of-character tho…

EDIT: searching on the C4668 suggests something about your include statements, check those too?

Updating my answer, looking at the output log more closely. I think
IrSoil
 is on to something. Seems like a msvc issue indeed. Have you recently updated Visual Studio? I would recommend doing a full “GenerateProjectFiles” and rebuild.

Thx, will try as soon as i can.

The-fix, for any kind of inconsistancy, or whenever I need to manually remove a class (.cpp/.h files):

  • Save everything
  • Close Unreal and VS
  • under your Unreal project folder delete the /binaries and /intermediate folders
  • start your project from the launcher
  • BEFORE ANYTHING ELSE: Tools → Refresh Visual Studio Project
  • Tools → Open Visual Studio

This will cause the project to rebuild your intermediary files and then update the project in VS so they are in-sync.

I have had to do this after I have updated VS on occasion, or if I say, mistakenly named a class and I want to ‘rename’ it (delete old and make new).
