**Renodx development requires CMake ≥ 3.20, Visual Studio 2022 or Clang, the Vulkan SDK, DirectX SDK, Reshade SDK, and additional libraries including spdlog and fmt pinned in `cmake/tool-versions.cmake` to compile the C++ modding framework and execute the test suite.**

Renodx is a C++‑based modding framework that injects shaders and enhances games through the Reshade API. Configuring a proper **renodx development environment** demands specific compilers, graphics SDKs, and build automation tools explicitly referenced throughout the repository source code and CI configuration files.

## Core Build System and Compilers

### CMake Configuration (Minimum Version 3.20)

The project relies on **CMake** as its primary build system generator. The root [`CMakeLists.txt`](https://github.com/clshortfuse/renodx/blob/main/CMakeLists.txt) drives the entire compilation process, defining project structure, compiler flags, and dependency fetching logic. Developers must install CMake version 3.20 or higher to process the configuration files correctly.

```bash
cmake -B build -S . -G "Visual Studio 17 2022" -A x64

```

### Visual Studio 2022 and MSVC

**Visual Studio 2022** serves as the primary development environment on Windows. The repository includes `make-sln.cmd`, a batch script that generates Visual Studio solution (`.sln`) files from the CMake configuration. The MSVC compiler is strictly required for DirectX SDK integration and for building the core Reshade hooks located in `src/games/*`.

### Clang Compiler Support

For developers preferring alternative toolchains, the repository supports **Clang** through dedicated CI workflows defined in [`.github/workflows/clang-x64.yml`](https://github.com/clshortfuse/renodx/blob/main/.github/workflows/clang-x64.yml). Clang is also employed for static analysis during continuous integration builds.

## Graphics SDKs and Rendering APIs

### Vulkan SDK

The test suite requires the **Vulkan SDK** to validate swap-chain upgrades and resource handling. Test project configurations such as [`test/resource_upgrade_transfer/CMakeLists.txt`](https://github.com/clshortfuse/renodx/blob/main/test/resource_upgrade_transfer/CMakeLists.txt) explicitly invoke the following CMake command:

```cmake
find_package(Vulkan QUIET)

```

This makes the Vulkan SDK mandatory for executing the verification tests that ensure proper graphics resource management.

### DirectX 11 and DirectX 12 SDKs

**DirectX SDKs** provide the headers and runtime libraries essential for the core Reshade integration and game-specific modules. Source files under `src/games/*` and test applications such as [`dx12_app.cpp`](https://github.com/clshortfuse/renodx/blob/main/dx12_app.cpp) rely on these SDKs to interface with DirectX graphics pipelines and compile DirectX-specific test apps.

### Reshade SDK

Renodx builds upon the **Reshade SDK** to inject shaders, buffers, and overlays into target games. The project compiles add-ons (`.addon64` binaries) that conform to this SDK's API specifications, as evidenced by the add-on source structure and generated binary outputs in the build directory.

## Shader Compilation Toolchain

### GLSLang and HLSL Compilers

Shader compilation requires **GLSLang** and **HLSL compilers** to process source files with extensions `.glsl`, `.hlsl`, and `.slang`. These tools compile test shaders and game-specific shader modules stored in `src/games/*` and associated test directories, ensuring the modded shaders are valid for runtime injection.

## Scripting and Build Automation Dependencies

### Python 3.8 or Higher

**Python 3.8+** powers utility scripts that manage release manifests and development environment setup. Files such as `scripts/setup-dev-env.ps1` and the helper logic in `scripts/generate-release-manifest.mjs` require Python to execute environment validation and build preparation tasks correctly.

### Node.js for JavaScript Automation

The repository uses **Node.js** to execute `.mjs` scripts that generate release manifests and perform build-time automation. These JavaScript modules handle versioning and packaging workflows alongside the Python utilities.

## Version-Pinned C++ Libraries

Third-party C++ dependencies are strictly version-controlled in **`cmake/tool-versions.cmake`**. This file pins exact versions to ensure reproducible builds across different development machines:

- **spdlog**: High-performance logging library
- **fmt**: Modern formatting library  
- **tinyxml2**: XML parsing for shader metadata
- **Boost**: Utility helpers for core framework functionality

CMake automatically fetches and links these libraries during the configuration phase based on the versions specified in `cmake/tool-versions.cmake`.

## Source Control and Optional Build Tools

### Git for Submodule Management

**Git** is required to clone the repository and initialize submodules tracked in `.gitmodules`. Several dependencies and external references are managed through Git submodules rather than system package managers, making Git essential for a complete source tree.

### Ninja Build System

While optional, **Ninja** serves as a fast backend for CMake builds and is used in CI workflows located in `.github/workflows/`. Ninja provides faster incremental builds compared to the default MSBuild generator on Windows and can be invoked via:

```bash
cmake -B build -G Ninja

```

## Environment Verification

The repository includes **`scripts/setup-dev-env.ps`1**, a PowerShell script that validates the presence of required SDKs and tools on fresh development machines. Running this script verifies that Vulkan, DirectX, Python, Node.js, and compiler toolchains are properly installed and accessible before attempting compilation.

## Summary

- **CMake ≥ 3.20** is mandatory, configured via the root [`CMakeLists.txt`](https://github.com/clshortfuse/renodx/blob/main/CMakeLists.txt)
- **Visual Studio 2022 (MSVC)** is the primary Windows compiler, though **Clang** is supported via CI workflows
- **Vulkan SDK** and **DirectX SDK** provide essential graphics headers for the rendering pipeline and test suite
- **Reshade SDK** enables the core injection functionality that defines the renodx framework
- **Python 3.8+** and **Node.js** execute build scripts and release automation utilities
- Third-party libraries (**spdlog**, **fmt**, **tinyxml2**, **Boost**) are version-pinned in `cmake/tool-versions.cmake`
- **Git** manages submodules, while **Ninja** offers an optional fast build backend for CMake

## Frequently Asked Questions

### What is the minimum CMake version required for renodx?

The repository requires **CMake 3.20 or higher**, as specified in the root [`CMakeLists.txt`](https://github.com/clshortfuse/renodx/blob/main/CMakeLists.txt). This version ensures compatibility with the modern CMake features used for dependency management and compiler flag configuration.

### Can I build renodx without Visual Studio?

Yes, though Visual Studio 2022 is the primary supported environment. The repository includes CI workflows for **Clang** in [`.github/workflows/clang-x64.yml`](https://github.com/clshortfuse/renodx/blob/main/.github/workflows/clang-x64.yml), allowing compilation with alternative compilers. However, you still need the Windows SDK and DirectX headers regardless of the compiler choice.

### Where are third-party dependency versions defined in renodx?

Exact versions of C++ libraries like spdlog, fmt, tinyxml2, and Boost are pinned in **`cmake/tool-versions.cmake`**. This file ensures reproducible builds across different development machines by constraining dependency versions rather than using floating ranges.

### Is the Reshade SDK bundled with the renodx repository?

The Reshade SDK is a required **external dependency**, not bundled source code. The renodx build system expects the SDK to be available for linking against the add-on interface, enabling the compilation of `.addon64` binaries that inject shaders and overlays into games.
