Mike-Solar ae908441c8 packaging: ship the Vulkan backend on all platforms, standard lib layout 
- Linux CD builds no longer disable Vulkan: the AppImage, deb, rpm and
  Arch packages now build and ship liboakvulkan (the AppImage deploys
  it via linuxdeploy --library so libvulkan is bundled too, and the
  verify step checks both backend libraries); deb/rpm dependencies gain
  libvulkan1/vulkan-loader; the Arch PKGBUILD gains vulkan-headers
- macOS CD installs vulkan-loader and exports VULKAN_SDK so
  find_package(Vulkan) locates the Homebrew loader (previously the
  Vulkan backend silently never built there)
- ffmpeg_bridge now installs to the standard lib directory with
  /../lib RPATH instead of the non-standard ffmpeg_bridge/bin
  layout (verified: editor, worker, oakgl and oakvulkan all resolve it)
- build guides (EN/ZH) document the macOS Vulkan backend dependencies
  and the VULKAN_SDK variable

构建指南

本文档介绍如何在 Windows、Linux 和 macOS 上从源码构建 Oak Video Editor。

依赖

  • CMake 3.20+
  • Ninja（推荐）
  • Qt 6（含私有头文件）
  • FFmpeg 8.0+ 开发库（Ubuntu/Debian 系统源里的版本通常太旧，见下文 Linux 章节）
  • OpenImageIO
  • OpenColorIO（2.x）
  • OpenEXR
  • Expat
  • PortAudio
  • OpenGL 头文件
  • Vulkan SDK（可选，Vulkan 渲染后端需要）
  • XKB common（Linux）

Windows（MSYS2）

本指南使用 MSYS2 的 UCRT64 工具链。

1. 安装 MSYS2

从 https://www.msys2.org/ 下载并安装 MSYS2，然后打开 MSYS2 UCRT64 终端。

2. 安装依赖

pacman -Syu
pacman -S --needed \
  mingw-w64-ucrt-x86_64-cmake \
  mingw-w64-ucrt-x86_64-ninja \
  mingw-w64-ucrt-x86_64-qt6-base \
  mingw-w64-ucrt-x86_64-qt6-tools \
  mingw-w64-ucrt-x86_64-ffmpeg \
  mingw-w64-ucrt-x86_64-openimageio \
  mingw-w64-ucrt-x86_64-opencolorio \
  mingw-w64-ucrt-x86_64-openexr \
  mingw-w64-ucrt-x86_64-fmt \
  mingw-w64-ucrt-x86_64-expat \
  mingw-w64-ucrt-x86_64-portaudio \
  mingw-w64-ucrt-x86_64-vulkan-headers \
  mingw-w64-ucrt-x86_64-vulkan-loader \
  mingw-w64-ucrt-x86_64-gcc

注意： Qt 6 私有头文件可能需要额外安装。如果 CMake 报告找不到私有头文件，请尝试安装 mingw-w64-ucrt-x86_64-qt6-base-private（如果仓库中有）。

3. 克隆并构建

# 克隆仓库
git clone --recursive https://github.com/OakVideoEditorCommunity/oak.git
cd oak

# 配置
cmake -S . -B build -G Ninja \
  -DCMAKE_BUILD_TYPE=Release \
  -DBUILD_QT6=ON

# 构建
cmake --build build --config Release

4. 运行测试（可选）

ctest --test-dir build --output-on-failure -C Release

Linux

Debian / Ubuntu

安装依赖（FFmpeg 需要自行从源码编译，因为系统源里的版本通常太旧）：

sudo apt-get update
sudo apt-get install -y \
  cmake ninja-build pkg-config nasm \
  qt6-base-dev qt6-base-dev-tools qt6-base-private-dev qt6-tools-dev qt6-tools-dev-tools \
  libopencolorio-dev libopenimageio-dev libopenexr-dev libexpat1-dev \
  portaudio19-dev libgl1-mesa-dev libvulkan-dev vulkan-headers libxkbcommon-dev

从源码编译 FFmpeg 8.0+：

git clone --branch n8.1.1 --depth 1 https://git.ffmpeg.org/ffmpeg.git ffmpeg-src
cd ffmpeg-src
./configure \
  --prefix="$PWD/../ffmpeg-install" \
  --enable-static \
  --disable-shared \
  --disable-doc \
  --disable-programs \
  --disable-avdevice \
  --disable-network \
  --enable-pic \
  --enable-gpl \
  --enable-version3
make -j$(nproc)
make install
cd ..

配置并构建：

cmake -S . -B build -G Ninja \
  -DBUILD_TESTS=ON -DBUILD_QT6=ON \
  -DFFMPEG_ROOT="$PWD/ffmpeg-install"
cmake --build build --config Release

运行测试：

ctest --test-dir build --output-on-failure -C Release

Fedora

安装依赖：

sudo dnf install -y \
  cmake ninja-build pkgconf-pkg-config \
  qt6-qtbase-devel qt6-qtbase-private-devel qt6-qttools-devel \
  ffmpeg-free-devel \
  OpenImageIO-devel \
  OpenColorIO-devel \
  openexr-devel \
  expat-devel \
  portaudio-devel \
  mesa-libGL-devel \
  vulkan-headers \
  vulkan-loader-devel \
  libxkbcommon-devel \
  gcc-c++ \
  bzip2-devel

配置并构建：

cmake -S . -B build -G Ninja -DBUILD_TESTS=ON -DBUILD_QT6=ON
cmake --build build --config Release

运行测试：

ctest --test-dir build --output-on-failure -C Release

Arch Linux

安装依赖：

sudo pacman -Syu
sudo pacman -S --needed \
  cmake ninja pkgconf \
  qt6-base qt6-tools \
  ffmpeg \
  openimageio \
  opencolorio \
  openexr \
  expat \
  portaudio \
  mesa \
  vulkan-headers \
  vulkan-icd-loader \
  libxkbcommon \
  fmt \
  gcc

注意： Arch Linux 的 qt6-base 包已经包含私有头文件。

配置并构建：

cmake -S . -B build -G Ninja -DBUILD_TESTS=ON -DBUILD_QT6=ON
cmake --build build --config Release

运行测试：

ctest --test-dir build --output-on-failure -C Release

macOS

macOS 现在是正式支持的平台。更详细的逐步指南请参见 build_macos-zh.md。

安装依赖：

brew update
brew install cmake ninja pkg-config qt@6 ffmpeg openimageio opencolorio openexr portaudio expat molten-vk vulkan-headers vulkan-loader

构建 OpenTimelineIO（可选，如需 OTIO 支持）：

git clone --depth 1 --branch v0.16.0 https://github.com/PixarAnimationStudios/OpenTimelineIO.git
cmake -S OpenTimelineIO -B OpenTimelineIO/build -G Ninja \
  -DOTIO_SHARED_LIBS=ON \
  -DOTIO_PYTHON_BINDINGS=OFF \
  -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_INSTALL_PREFIX="${PWD}/otio-install"
cmake --build OpenTimelineIO/build
cmake --install OpenTimelineIO/build

配置并构建：

export PATH="$(brew --prefix qt@6)/bin:$PATH"
export CMAKE_PREFIX_PATH="$(brew --prefix qt@6)"
export OTIO_LOCATION="${PWD}/otio-install"
export OCIO_LOCATION="$(brew --prefix opencolorio)"
# 让 CMake 的 FindVulkan 找到 Homebrew 的 Vulkan loader（可选，
# 启用 Vulkan 渲染后端）
export VULKAN_SDK="$(brew --prefix vulkan-loader)"

cmake -S . -B build -G Ninja -DBUILD_TESTS=ON -DBUILD_QT6=ON \
  -DOTIO_LOCATION="${OTIO_LOCATION}" \
  -DOCIO_LOCATION="${OCIO_LOCATION}"
cmake --build build --config Release

运行测试：

ctest --test-dir build --output-on-failure -C Release

构建选项

选项 默认值 说明
BUILD_TESTS OFF 构建单元测试
BUILD_DOXYGEN OFF 构建 Doxygen 文档
USE_WERROR OFF 将警告视为错误
BUILD_QT6 ON 使用 Qt 6 而非 Qt 5
OTIO_LOCATION - OpenTimelineIO 安装路径（可选）
OCIO_LOCATION - OpenColorIO 安装路径
OAK_ENABLE_DYNAMIC_RENDER_BACKEND ON 构建动态渲染后端库（liboakgl.so / liboakvulkan.so）

故障排除

找不到 Qt 6

确保 Qt 6 在 PATH 和 CMake prefix path 中：

# Linux / macOS
export PATH="/path/to/qt6/bin:$PATH"
export CMAKE_PREFIX_PATH="/path/to/qt6"

# Windows（MSYS2）
export PATH="/ucrt64/bin:$PATH"

缺少私有头文件

如果看到缺少 Qt 私有头文件的错误，请安装对应发行版的私有开发包（例如 Debian/Ubuntu 上的 qt6-base-private-dev，Fedora 上的 qt6-qtbase-private-devel）。

FFmpeg 版本太旧

如果遇到 AV_PIX_FMT_GRAYF16 was not declared in this scope 之类的错误，说明你的 FFmpeg 版本太旧（Oak 需要 8.0+）。请从源码编译：

git clone --branch n8.1.1 --depth 1 https://git.ffmpeg.org/ffmpeg.git ffmpeg-src
cd ffmpeg-src
./configure \
  --prefix="$PWD/../ffmpeg-install" \
  --enable-static \
  --disable-shared \
  --disable-doc \
  --disable-programs \
  --disable-avdevice \
  --disable-network \
  --enable-pic \
  --enable-gpl \
  --enable-version3
make -j$(nproc)
make install
cd ..

然后在 CMake 中加上 -DFFMPEG_ROOT="$PWD/ffmpeg-install"。
