SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill simplifies the complex process of configuring Unreal Engine modules, plugins, and build targets, helping you avoid common build errors and optimize your project's compilation process.

Core Features & Use Cases

  • Build.cs Configuration: Understand and modify Build.cs files for managing module dependencies, include paths, and API exports.
  • Plugin Setup: Learn how to create and configure new Unreal Engine plugins, including their .uplugin manifest and source structure.
  • Build Error Resolution: Get guidance on diagnosing and fixing common linker, compiler, and IWYU errors.
  • Use Case: You need to add a new third-party library to your Unreal Engine project. This Skill will guide you through modifying your module's Build.cs file to correctly link the library and expose its headers.

Quick Start

Use the ue-module-build-system skill to add 'MyNewLibrary' as a private dependency to the current module.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I configure Unreal Engine Build.cs files for third-party library dependencies?▼

To configure Unreal Engine Build.cs files for third-party libraries, you modify the module's Build.cs file to correctly link the library, define include paths, and set up API export macros for proper compilation.

Why does my Unreal Engine C++ project fail to compile with linker and IWYU errors?▼

Unreal Engine C++ linker and IWYU errors usually occur due to incorrect PCH settings, missing module dependencies, or improper include directives. Resolving these requires diagnosing Build.cs configurations and adjusting API export macros.

What is the correct way to set up a new Unreal Engine plugin source structure?▼

Setting up a new Unreal Engine plugin requires creating a proper source structure and configuring the .uplugin manifest file. This involves defining the plugin's modules and their dependencies within the Unreal Engine build system.

How do I manage Unreal Engine module dependencies in Target.cs configurations?▼

You manage Unreal Engine module dependencies in Target.cs configurations by specifying the required modules for different build targets. This ensures the correct C++ modules are compiled and linked based on the project's Target.cs settings.

When do I need to use API export macros in Unreal Engine C++ modules?▼

API export macros are needed in Unreal Engine C++ modules when you want to expose classes and functions to other modules. Properly configuring these macros in your Build.cs file prevents linker errors during the build process.

Does the Unreal Engine build system support managing PCH and IWYU settings simultaneously?▼

Yes, the Unreal Engine build system supports managing PCH and IWYU settings together. You can configure these settings in your Build.cs file to optimize compilation times and ensure include-what-you-use compliance.
