Fresh install of 5.5.4, new project, 42 compile errors

Are you using MSVC or Clang? Although the project is new, let’s just do a few sanity checks.

  1. Go to YourProjectName.Build.cs and see if the Dependencies array is not empty, then Generate Project Files.

  2. Go to BuildConfiguration.xml found at:

  • %appdata%\Unreal Engine\UnrealBuildTool\
  • YourProjectDirectory\Saved\UnrealBuildTool\

Inside the xml file, make sure it has the default text, it should look like this:

<?xml version="1.0" encoding="utf-8" ?>
<Configuration xmlns="https://www.unrealengine.com/BuildConfiguration">
</Configuration>

Your issue must have to do with UBT, just need to know what is causing it…
