build-remix

name	build-remix
description	Build dxvk-remix from source. Use when the user asks to compile, build, or rebuild the project, or when code changes need to be compiled and tested.

Build dxvk-remix

All commands run in PowerShell from the repo root.

Prerequisites

Windows 10+, Visual Studio 2019 (2022 may work), Windows SDK 10.0.19041.0, Meson 1.8.2+, Vulkan SDK 1.4.313.2+, Python 3.9+.

Build Configurations

Build Directory	Flavour	Use Case
_Comp64Debug	debug	Full debug instrumentation, slow runtime
_Comp64DebugOptimized	debugoptimized	Asserts enabled, near-release speed (recommended for development)
_Comp64Release	release	Fastest runtime

First-Time Setup

All configurations

.\build_dxvk_all_ninja.ps1

This also generates the Visual Studio solution at _vs/dxvk-remix.sln.

Single configuration

.\build_dxvk.ps1 -BuildFlavour debugoptimized -BuildSubDir _Comp64DebugOptimized -Backend ninja -EnableTracy false

Incremental Build (day-to-day)

Once a build directory exists, rebuild only changed files:

meson compile -C _Comp64DebugOptimized

Always use meson compile, never call ninja directly. meson compile auto-activates the MSVC environment; calling ninja directly will fail because cl.exe is not on PATH.

This compiles all C++ targets and shaders together. Calling meson compile is faster than build_dxvk.ps1 since it skips the setup step.

Reconfigure After Dependency Changes

Run inside the relevant build directory when dependency paths change (e.g. new Vulkan SDK):

cd _Comp64DebugOptimized; meson --reconfigure

Shaders Only

Quick shader syntax check when C++ hasn't changed:

meson compile -C _Comp64DebugOptimized rtx_shaders

Shader compiler is slangc.exe (Slang language). Compiled SPIR-V output goes to _Comp64DebugOptimized/src/dxvk/rtx_shaders/*.spv.
