Build Requirements

Prerequisites

To build this project, you need to install the following tools:

1. C Compiler: LLVM-mingw

   • Download from: https://github.com/mstorsjo/llvm-mingw/releases
   • Use the UCRT runtime version

2. CMake

   • Download from: https://cmake.org/download/

3. Ninja

   • Download from: https://github.com/ninja-build/ninja/releases
   • Or install via MSYS2: pacman -S ninja

4. MSYS2 (for OpenSSL dependency)

   • Download from: https://www.msys2.org/
   • Required because moonlight-common-c depends on OpenSSL, which is not included in the minimal LLVM-mingw distribution

Setup Instructions

1. Install LLVM-mingw (UCRT version) and add it to your PATH
2. Install CMake and add it to your PATH
3. Install Ninja and add it to your PATH
4. Install MSYS2 and install OpenSSL (UCRT version):

   pacman -S --needed mingw-w64-ucrt-x86_64-openssl mingw-w64-ucrt-x86_64-pkg-config

5. Add MSYS2's UCRT64 bin directory to your PATH (e.g., C:\msys64\ucrt64\bin)

Build

1. Clone the repository and initialize submodules:

   git clone https://github.com/flarexio/game.git
   cd game
   git submodule update --init --recursive

2. Build opus (PowerShell):

   cd thirdparty/opus
   
   # Configure and build
   mkdir build; cd build
   cmake -G "Ninja" -S .. -B . `
     -DCMAKE_BUILD_TYPE=Release `
     -DOPUS_BUILD_SHARED_LIBRARY=ON `
     -DOPUS_BUILD_TESTING=OFF `
     -DOPUS_BUILD_PROGRAMS=OFF `
     -DCMAKE_C_COMPILER=clang `
     -DCMAKE_C_COMPILER_TARGET=x86_64-w64-mingw32
   
   cmake --build . --parallel

3. Build moonlight-common-c (PowerShell):

   cd thirdparty/moonlight-common-c
   
   # Set environment variables
   $env:CC = "clang"
   $env:CXX = "clang++"
   $env:OPENSSL_ROOT_DIR = "C:/msys64/ucrt64"
   $env:CMAKE_PREFIX_PATH = "C:/msys64/ucrt64"
   $env:PATH = "C:\msys64\ucrt64\bin;$env:PATH"
   
   # Configure and build
   mkdir build; cd build
   cmake -G "Ninja" -S .. -B . `
     -DCMAKE_BUILD_TYPE=Release `
     -DBUILD_SHARED_LIBS=ON `
     -DCMAKE_C_COMPILER=clang `
     -DCMAKE_RC_COMPILER=llvm-rc `
     -DCMAKE_C_COMPILER_TARGET=x86_64-w64-mingw32 `
     -DOPENSSL_ROOT_DIR="C:/msys64/ucrt64" `
     -DOPENSSL_USE_STATIC_LIBS=OFF
   
   cmake --build . --parallel

4. Set up runtime environment:

   Before running the application, ensure the following paths are in your PATH environment variable:

   • thirdparty\opus\build (for opus.dll)
   • thirdparty\moonlight-common-c\build (for moonlight-common-c.dll)
   • C:\msys64\ucrt64\bin (for OpenSSL DLLs: libssl-3-x64.dll, libcrypto-3-x64.dll)

5. Build the project:
