Repository Set-Up

Clone the Repository

Use the following Git command to create a local copy of the GFXReconstruct repository:

git clone https://github.com/LunarG/gfxreconstruct.git

Repository Dependencies

The GFXReconstruct project has both required and optional dependencies. See the External Dependencies README.md for details regarding individual dependencies.

Required dependencies are included with the GFXReconstruct repository as Git submodules. After cloning the repository, execute the following command from within the GFXReconstruct project folder to initialize the submodules:

git submodule update --init

Submodules will be updated periodically as the GFXReconstruct project is updated to support new Vulkan API releases. To obtain submodule updates, execute the following command from within the GFXReconstruct project folder:

git submodule update

Submodules will need to be updated when the repository status (e.g. git status) shows the submodule folders as having been modified after a repository update (e.g. git pull).

Common build instructions

For desktop builds, there is a Python 3 build script, scripts/build.py, that can be used to update Git submodule dependencies, configure, and build the GFXReconstruct software. The script works with both Windows and Linux, and requires Python 3.5 or above.

A 64 bit ARM Windows build can be achieved on an ARM64 Windows host system with the following command:

python scripts/build.py -a arm64

By default, the script performs some optional build steps that are intended for developer builds. If the target build system has not been configured for developer builds as described in CONTRIBUTING.md, the script can be run with the following options to disable the developer build steps:

python scripts/build.py --skip-check-code-style --skip-tests

The above invocation will run on a single core. To speed up the build with parallel processes, the standard CMake environment variable CMAKE_BUILD_PARALLEL_LEVEL may be used. For example, to use eight processes from within Bash:

CMAKE_BUILD_PARALLEL_LEVEL=8 python scripts/build.py --skip-check-code-style --skip-tests

By default, the script builds support for capturing and replaying Direct3D 12. To omit Direct3D 12 components, specify --skip-d3d12-support. For example:

python scripts/build.py --skip-d3d12-support

Run the script with the -h option for additional usage information.

Building for Windows

Windows Development Environment Requirements

  • Microsoft Visual Studio
    • Supported Versions
    • The Community Edition for each of the above versions is sufficient
  • CMake (Version 3.16.3 or newer)
    • The build instructions assume that CMake has been added to the system PATH
  • Git Client Support

Windows Build - Microsoft Visual Studio

The general approach is to first run CMake to generate the Visual Studio project files. Then either run CMake with the --build option to build from the command line or use the Visual Studio IDE to open the generated solution and work with the solution interactively.

Generate Visual Studio Project Files with CMake

Change your current directory to the top level directory for the cloned GFXReconstruct repository, create a build folder, and generate the Visual Studio project files.

The following example demonstrates the generation of project files for the Visual Studio 2017 x64 build configuration:

cd gfxreconstruct
mkdir build
cmake -H. -Bbuild -G "Visual Studio 15 Win64"

The following commands can be used to generate project files for different variations of the Visual Studio 2017 WIN32 and x64 build configurations:

  • 64-bit for VS 2017: cmake -H. -Bbuild -G "Visual Studio 15 Win64"
  • 32-bit for VS 2017: cmake -H. -Bbuild -G "Visual Studio 15"

Running any of the above commands will create a Windows solution file named GFXReconstruct.sln in the build directory.

Visual Studio configuration will include support for capturing and replaying Direct3D 12 by default. To omit Direct3D 12 components, specify -DD3D12_SUPPORT=OFF to cmake.

At this point, you can build the solution from the command line or open the generated solution with Visual Studio.

Note: The D3D12 build uses Windows 10 SDK 10.0.20348.0. Other Windows SDK versions may not be compatible. If you need to specify a Windows SDK, please use -DCMAKE_SYSTEM_VERSION=10.0.20348.0. If Python code generation is required, the shell used to run it should set the environment variable WindowsSDKVersion=10.0.20348.0.

When generating a native build on an ARM64 Windows host the Visual Studio Installer can be used to install the required Windows SDK version, 10.0.20348.0. Once the correct Windows SDK is installed, from a newly opened developer command prompt for Visual Studio 2022, the following CMake invocation will generate a Visual Studio solution and projects.

cmake -H. -Bbuild -G "Visual Studio 17 2022" -A ARM64 -DCMAKE_SYSTEM_VERSION=10.0.20348.0

Build the Solution From the Command Line

To build the Debug configuration, run the following command from the build directory:

cmake --build .

To build the Release configuration, run the following command from the build directory:

cmake --build . --config Release

Build the Solution With Visual Studio

Launch Visual Studio and open the GFXReconstruct.sln solution file from the build folder. You may select "Debug" or "Release" from the Solution Configurations drop-down list. Start a build by selecting the Build->Build Solution menu item.

Building for Linux

Required Package List

Building on Linux requires the installation of the following packages:

  • A C++ compiler with C++-14 support
  • Git
  • CMake
  • X11 + XCB and/or Wayland development libraries

Ubuntu

GFXReconstruct is built and tested for SDK development using Ubuntu 20.04 and 22.04. Older Ubuntu releases are unsupported.

For Ubuntu, the required packages can be installed with the following command:

sudo apt-get install git cmake build-essential libx11-xcb-dev libxcb-keysyms1-dev \
        libwayland-dev libxrandr-dev zlib1g-dev liblz4-dev libzstd-dev

For 32-bit builds (DXVK might require 32-bit):

sudo apt-get install g++-multilib libx11-xcb-dev:i386 libxcb-keysyms1-dev:i386 \
        libwayland-dev:i386 libxrandr-dev:i386 zlib1g-dev:i386 liblz4-dev:i386 libzstd-dev:i386

For arm64 builds (cross compilation):

sudo apt-get install g++-aarch64-linux-gnu

Fedora

For Fedora, the required packages can be installed with the following command:

sudo dnf install git cmake libxcb-devel libX11-devel xcb-util-keysyms-devel \
        libXrandr-devel wayland-devel zlib-devel lz4-devel libzstd-devel g++

For arm64 builds (cross compilation):

sudo dnf install g++-aarch64-linux-gnu

Linux Build

The general approach is to run CMake to generate makefiles. Then either run CMake with the --build option or make to build from the command line.

Use CMake to Create the Makefiles

Change your current directory to the top level directory for the cloned GFXReconstruct repository, create a build folder, and generate the make files.

The following example demonstrates makefile generation for a 64-bit Debug build:

cd gfxreconstruct
mkdir build
cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=Debug

The following commands can be used to generate makefiles for different variations of Debug and Release, as well as different architectures. -DCMAKE_BUILD_TYPE is used to specify Debug or Release build profiles and the -DCMAKE_TOOLCHAIN_FILE with a matching toolcain file can be changed to compile for different architectures:

  • 64-bit x64 Release (default): cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=Release
  • 32-bit x86 Debug: cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=Debug -DCMAKE_TOOLCHAIN_FILE=cmake/toolchain/linux_x86_32.cmake
  • 32-bit x86 Release: cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=cmake/toolchain/linux_x86_32.cmake
  • 32-bit arm Release: cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=cmake/toolchain/linux_arm.cmake
  • 64-bit arm Release: cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=cmake/toolchain/linux_arm64.cmake

For 32-bit builds, the 32-bit versions of the required packages specified above must be installed.

Build the Project

Run either the make or cmake --build . command from the build directory to build the GFXReconstruct project source.

For faster builds on multi-core systems with make, use make -jN to specify the number of jobs that are allowed to run at the same time with the build. For example:

make -j4

For build systems that support ccache, it can be enabled with the CMake -DUSE_CCACHE=On option.

Install the project

Files can be installed to "/usr/local/" with sudo make install

For Linux, the default install directory /usr/local can be changed by setting CMake's CMAKE_INSTALL_PREFIX variable. For example, to install to a "/tmp/gfxreconstruct" directory, run cmake -DCMAKE_INSTALL_PREFIX=/tmp/gfxreconstruct . from gfxreconstruct's root source directory. Then install with make install.

Building for Android

Android Development Requirements

Additional Linux Command-Linux Prerequisites

Additional requirements for building from the Linux command-line:

  • Define ANDROID_HOMEto be the path to the SDK installed on your system by Android Studio.
    • Refer to Android Studio to find out where the files are installed
      • NOTE: For older Android Stud io's you may also have to set ANDROID_SDK_ROOT to the same value
    • For example:
        export ANDROID_HOME=$HOME/Android/Sdk`
  • Define JAVA_HOME to the path to the directory of the JDK.
    • For example:
      export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.18.0.10-1.fc37.x86_64
  • Make the gradlew script executable
    • chmod +x android/gradlew

Android Build

Building with Gradle

Run the following command from the gfxreconstruct/android folder to perform a debug build with Gradle:

On Windows:

gradlew assembleDebug

On Linux:

./gradlew assembleDebug

To perform a release build, replace the assembleDebug task name with assembleRelease.

Building with Android Studio

  1. Open Android Studio
  2. Choose Import Project, browse to the gfxreconstruct/android folder, and click OK.
    • This option is available through either the opening Dialog box or the File -> New -> Import Project... menu item
    • If import succeeds, the following two project modules will be displayed by the Project browser:
    • layer - The GFXReconstruct capture layer for recording Vulkan API data
    • replay - The GFXReconstruct tool to replay GFXR capture files
  3. Build the project by selecting the Build -> Make Project menu item or pressing Ctrl+F9

Adding the Layer to Existing Projects

The GFXReconstruct layer project may be added as a dependency of an existing Android application project. After the layer has been added as an application dependency, it will be built when the application is built and automatically included with the application's APK. A manifest file provided by the GFXReconstruct layer project will also be merged with the application's Manifest file, adding uses-permission elements for the permissions required by the layer (e.g. WRITE_EXTERNAL_STORAGE).

To add the GFXReconstruct project as an application dependency, first add the following lines to the application's settings.gradle file, replacing the {gfxreconstruct_root} value with the actual path to the top level GFXReconstruct project folder:

include ':VkLayer_gfxreconstruct'
project(':VkLayer_gfxreconstruct').projectDir = file('{gfxreconstruct_root}/android/layer')

Next, add the following lines to the application's build.gradle file:

    dependencies {
        implementation project(':VkLayer_gfxreconstruct')
    }

NOTE: Make sure it is the app version of build.gradle (usually found in an app folder). This may not necessarily be the top build.gradle in the tree.

Adding the Vulkan Validation Layer to gfxrecon-replay

  1. Download the latest Android Vulkan Validation Layer binaries from the GitHub release page
  2. Extract the prebuilt layer binaries and include them in the gfxrecon-replay APK by adding them to the following directories:
gfxreconstruct/android/tools/replay/src/main/jniLibs/
    arm64-v8a/
        libVkLayer_khronos_validation.so
    armeabi-v7a/
        libVkLayer_khronos_validation.so
    x86/
        libVkLayer_khronos_validation.so
    x86-64/
        libVkLayer_khronos_validation.so
  1. Rebuild and deploy gfxrecon-replay

The Android Vulkan Validation Guide has further instructions for advanced validation layer usage on Android
