Default: OFF
VKB_VALIDATION_LAYERS_GPU_ASSISTED
Enable GPU assisted validation layers, used primarily for VK_EXT_descriptor_indexing.
Default: OFF
VKB_VULKAN_DEBUG
Enable VK_EXT_debug_utils or VK_EXT_debug_marker, if supported. This enables debug names for Vulkan objects, and markers/labels in command buffers. + See the debug utils sample for more information.
Default: ON
VKB_PROFILING
Enable profiling using the Tracy profiler.
We currently use Tracy v0.10.0 if you do not use the correct Tracy Profiler version as the Tracy Client version used in Sample you will get a protocol mismatch error.
Windows users can download the profiler from the Tracy v0.10.0 release page Other platforms require the user to build the profiler from source see the Tracy documentation (pdf) for more information on how to build for your platform.
Tracy is not currently enabled for Android builds. In the future, we may add support for this.
Default: OFF
Quality Assurance
We use a small set of tools to provide a level of quality to the project. These tools are part of our CI/CD process. If your local environment does not have the same versions of the tools we use in the CI you may see some errors or warnings pop-up when pushing.
For up-to date version information please see the repositories for the individual tools

3D models
Most of the samples require 3D models downloaded from https://github.com/KhronosGroup/Vulkan-Samples-Assets.
That repository is referenced as a git submodule by this project so if you followed the clone instructions in the project readme you will already have the models locally under ./assets/
.
On Android, Gradle will run CMake which will sync assets to the device if there has been a change.
However, to sync them manually you may run the following command to ensure up to date assets are on the device:
adb push --sync assets /sdcard/Android/data/com.khronos.vulkan_samples/files/
adb push --sync shaders /sdcard/Android/data/com.khronos.vulkan_samples/files/
Performance data
In order for performance data to be displayed, profiling needs to be enabled on the device. Some devices may disable it by default.
Profiling can be enabled via adb:
adb shell setprop security.perf_harden 0
Performance data is captured using HWCPipe. For details on this project and how to integrate it in your pipeline, visit: https://github.com/ARM-software/HWCPipe
Windows
Clang Format and Visual Studio
It is recommended to use clang-format-15
, which is compatible with the styles in our .clang-format
file.
It is also used by CI and is a basic version installed with Visual Studio 2022.
Go to the LLVM downloads page to get clang.
Build with CMake and Visual Studio
Please make sure, when running any sample, that you either:
Enable Developer Mode
Run Command Prompt or Visual Studio as administrator
Step 1.
The following command will generate the VS project
cmake -G "Visual Studio 15 2017 Win64" -S . -Bbuild/windows
(Prior to CMake v3.13)
cmake -G "Visual Studio 15 2017 Win64" . -Bbuild/windows
(New in CMake v3.14. Visual Studio 2019 must be installed)
cmake -G "Visual Studio 16 2019" -A x64 -S . -Bbuild/windows
(New in CMake v3.21. Visual Studio 2022 must be installed)
cmake -G "Visual Studio 17 2022" -A x64 -S . -Bbuild/windows
Open the vulkan_samples.sln VS project inside build/windows and build with Ctrl-Shift-B. To run Vulkan Samples, use Visual Studio’s Debug Properties selection and set the Debugging Command Arguments to --help. Click the "Local Windows Debugger" button and you should see the help output in the terminal. For convenience, the default setting is to run the hello_triangle sample; just edit that to your desired sample to run.
Alternatively, for command line builds use the steps below:
Step 2.
Build the Visual Studio project
cmake --build build/windows --config Release --target vulkan_samples
Step 3.
Run the Vulkan Samples application
build\windows\app\bin\Release\AMD64\vulkan_samples.exe
Linux
Build with CMake
Step 1.
The following command will generate the project
cmake -G "Unix Makefiles" -Bbuild/linux -DCMAKE_BUILD_TYPE=Release
Step 2.
Build the project
cmake --build build/linux --config Release --target vulkan_samples -j$(nproc)
Step 3.
Run the Vulkan Samples application to display the help message
./build/linux/app/bin/Release/x86_64/vulkan_samples --help
macOS
Dependencies
-
CMake v3.12+ (Apple Silicon requires at least 3.19.2)
-
Xcode v12 for Apple Silicon
-
Command Line Tools (CLT) for Xcode
xcode-select --install
-
Vulkan SDK - Download and Install the Vulkan SDK with default options
Build with CMake and Xcode
Step 1.
The following command will generate the project
cmake -G Xcode -Bbuild/mac-xcode -DCMAKE_BUILD_TYPE=Release
Open the vulkan_samples Xcode project inside build/mac-xcode and build with command-B. To run Vulkan Samples, use Xcode’s edit-scheme selection and set the arguments to --help. Click the "Play" button and you should see the help output in the terminal. For convenience, the default setting is to run the hello_triangle sample; just edit that to your desired sample to run.
Alternatively, for command line builds use the steps below:
cmake -Bbuild/mac -DCMAKE_BUILD_TYPE=Release
Step 2.
Build the project
cmake --build build/mac --config Release --target vulkan_samples -j$(sysctl -n hw.ncpu)
Step 3.
Run the Vulkan Samples application to display the help message
./build/mac/app/bin/Release/<arm64|x86_64>/vulkan_samples --help
iOS
Dependencies
-
CMake v3.28+ (Apple xcframeworks require at least 3.28)
-
Xcode v12 for Apple Silicon
-
Command Line Tools (CLT) for Xcode
xcode-select --install
-
Vulkan SDK - Download and Install the Vulkan SDK making sure "Development libraries for iOS" is selected
-
Vulkan at least version 1.3.278 to get the frameworks
Set your environment variables
NB: For iOS you must run the setup-env.sh located inside the Vulkan SDK’s iOS directory
source /PATH/TO/VULKAN/SDK/iOS/setup-env.sh
Build with CMake and Xcode
Step 1.
The following command will generate the project
cmake -G Xcode -Bbuild/ios -DCMAKE_BUILD_TYPE=Release -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphoneos -DCMAKE_OSX_DEPLOYMENT_TARGET=13.0 -DCMAKE_XCODE_ATTRIBUTE_ONLY_ACTIVE_ARCH=YES -DCMAKE_OSX_ARCHITECTURES=arm64 -DCMAKE_IOS_INSTALL_COMBINED=NO -DCMAKE_XCODE_ATTRIBUTE_DEVELOPMENT_TEAM="XXXX" -DMACOSX_BUNDLE_GUI_IDENTIFIER="com.YYYY.vulkansamples"
NB: You MUST change the XXXX in the above to your TeamID (or Organizational Unit identifier in your Apple Development certificate) for code signing, and YYYY to your bundle identifier. iOS will NOT allow the application to run without code signing and bundle identifier setup.
Alternatively, you can build for the iOS Simulator without code signing or specifying a bundle identifier (a default bundle id will be used). However, depending on your host architecture, you MUST select either arm64 (Apple Silicon) or x86_64 in the command below
cmake -G Xcode -Bbuild/ios-sim -DCMAKE_BUILD_TYPE=Release -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphonesimulator -DCMAKE_OSX_DEPLOYMENT_TARGET=13.0 -DCMAKE_XCODE_ATTRIBUTE_ONLY_ACTIVE_ARCH=YES -DCMAKE_OSX_ARCHITECTURES=<arm64|x86_64> -DCMAKE_IOS_INSTALL_COMBINED=NO
Step 2.
Build the project
It’s recommended to open the vulkan_samples Xcode project that is generated inside build/ios or build/ios-sim and build with command-B.
Alternatively, you can build with cmake as shown here
cmake --build build/ios --config Release --target vulkan_samples -j$(sysctl -n hw.ncpu) -- -sdk iphoneos -allowProvisioningUpdates
Step 3.
Run the Vulkan Samples application
To run Vulkan Samples, one must have an iOS physical or simulator device provisioned and working with Xcode. Open the Xcode project and ensure that can build/install to a device through Xcode normally. Once the bundle is created from the build command in Step 2, use the edit-scheme selection in Xcode and set the arguments to --help. Click the "Play" button and you should see the help output in the terminal. For convenience, the default setting is to run the hello_triangle sample; just edit that to your desired sample to run.
Android
Dependencies
For all dependencies set the following environment variables:
-
JDK 8+
JAVA_HOME=<SYSTEM_DIR>/java
-
Android SDK
ANDROID_HOME=<WORK_DIR>/android-sdk
-
CMake v3.16+
-
Android NDK r23+
ANDROID_NDK_HOME=<WORK_DIR>/android-ndk
We use this environment in the CI Android NDK Repository
It is highly recommended to install Android Studio to build, run and trace the sample project. Android Studio uses the following plugins/tools to build samples:
-
Android Gradle Plugin
-
CMake Plugin, which installs and uses Ninja
-
NDK
Their versions are configured in the build.gradle.in and app.build.gradle.in files; when updating these versions, refer to the official documentation for the recommended combinations.
Build with Gradle
Generate the gradle project
To generate the gradle project, run the following command:
./scripts/generate.py android
A new folder will be created in the root directory at build\android_gradle
Install dependencies
Android Gradle Plugin (used by Android Studio) may not auto install dependencies. You will need to install them if they have not been installed:
-
Find the configured versions in
build/android_gradle/app/build.gradle
, or its template filebldsys/cmake/template/gradle/app.build.gradle.in
-
Install them with Android Studio or sdkmanager command line tool. For example, to install AGP port CMake 3.22.1 and NDK version 25.1.8937393 on Linux, do the following:
yes | ${your-sdk}/cmdline-tools/latest/bin/sdkmanager --licenses ${your-sdk}/cmdline-tools/latest/bin/sdkmanager --install "ndk;25.1.8937393" --channel=3 ${your-sdk}/cmdline-tools/latest/bin/sdkmanager --install "cmake;3.22.1" --channel=3
Build with Android Studio
With Android Studio you can open the build/android_gradle/build.gradle
project, compile and run the project from here.
The lastest Android Studio release is recommended.
If you have agreed with the licenses previously on your development system, Android Studio will automatically install, at the start up time, CMake and NDK with the version configured in your build/android-gradle/build.gradle
.
Otherwise (or if the installation failed), you need to install the required CMake and NDK manually, refer to the official instructions for the detailed steps.
The default installed locations are:
-
$SDK-ROOT-DIR/ndk/$ndkVersion for NDK.
-
$SDK-ROOT-DIR/cmake/$cmake-version for CMake.
Android Studio will use the above default locations without any environment variable requirement; if you want to use the same NDK and CMake versions for other purpose, you can simply configure your environment variables to these locations. If you do set up the NDK and CMake environment variables, Android Studio will use them instead of the default locations.
