+## Repository Content
+
+This repository contains the source code necessary to build the following components:
+
+- vulkaninfo
+- vkcube and vkcubepp demos
+- mock ICD
+
+### Installed Files
+
+The `install` target installs the following files under the directory
+indicated by *install_dir*:
+
+- *install_dir*`/bin` : The vulkaninfo, vkcube and vkcubepp executables
+- *install_dir*`/lib` : The mock ICD library and JSON (Windows) (If INSTALL_ICD=ON)
+- *install_dir*`/share/vulkan/icd.d` : mock ICD JSON (Linux/MacOS) (If INSTALL_ICD=ON)
-[](#repo-set-up)
+The `uninstall` target can be used to remove the above files from the install
+directory.
## Repository Set-Up
### Display Drivers
-This repository does not contain a Vulkan-capable driver.
-Before proceeding, it is strongly recommended that you obtain a Vulkan driver from your
-graphics hardware vendor and install it properly.
+This repository does not contain a Vulkan-capable driver. You will need to
+obtain and install a Vulkan driver from your graphics hardware vendor or from
+some other suitable source if you intend to run Vulkan applications.
### Download the Repository
To create your local git repository:
- git clone https://github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers
+ git clone https://github.com/KhronosGroup/Vulkan-Tools.git
+
+### Repository Dependencies
+
+This repository attempts to resolve some of its dependencies by using
+components found from the following places, in this order:
+
+1. CMake or Environment variable overrides (e.g., -DVULKAN_HEADERS_INSTALL_DIR)
+1. LunarG Vulkan SDK, located by the `VULKAN_SDK` environment variable
+1. System-installed packages, mostly applicable on Linux
+
+Dependencies that cannot be resolved by the SDK or installed packages must be
+resolved with the "install directory" override and are listed below. The
+"install directory" override can also be used to force the use of a specific
+version of that dependency.
+
+#### Vulkan-Headers
+
+This repository has a required dependency on the
+[Vulkan Headers repository](https://github.com/KhronosGroup/Vulkan-Headers).
+You must clone the headers repository and build its `install` target before
+building this repository. The Vulkan-Headers repository is required because it
+contains the Vulkan API definition files (registry) that are required to build
+the mock ICD. You must also take note of the headers install directory and
+pass it on the CMake command line for building this repository, as described
+below.
+
+Note that this dependency can be ignored if not building the mock ICD
+(CMake option: `-DBUILD_ICD=OFF`).
+
+#### glslang
+
+This repository has a required dependency on the `glslangValidator` (shader
+compiler) for compiling the shader programs for the vkcube demos.
+
+The CMake code in this repository downloads release binaries of glslang if a
+build glslang repository is not provided. The glslangValidator is obtained
+from this set of release binaries.
+
+If you don't wish the CMake code to download these binaries, then you must
+clone the [glslang repository](https://github.com/KhronosGroup/glslang) and
+build its `install` target. Follow the build instructions in the glslang
+[README.md](https://github.com/KhronosGroup/glslang/blob/main/README.md)
+file. Ensure that the `update_glslang_sources.py` script has been run as part
+of building glslang. You must also take note of the glslang install directory
+and pass it on the CMake command line for building this repository, as
+described below.
+
+Note that this dependency can be ignored if not building the vkcube demo
+(CMake option: `-DBUILD_CUBE=OFF`).
+
+### Build and Install Directories
+
+A common convention is to place the build directory in the top directory of
+the repository with a name of `build` and place the install directory as a
+child of the build directory with the name `install`. The remainder of these
+instructions follow this convention, although you can use any name for these
+directories and place them in any location.
+
+### Building Dependent Repositories with Known-Good Revisions
+
+There is a Python utility script, `scripts/update_deps.py`, that you can use to
+gather and build the dependent repositories mentioned above. This script uses
+information stored in the `scripts/known_good.json` file to check out dependent
+repository revisions that are known to be compatible with the revision of this
+repository that you currently have checked out. As such, this script is useful
+as a quick-start tool for common use cases and default configurations.
+
+For all platforms, start with:
+
+ git clone git@github.com:KhronosGroup/Vulkan-Tools.git
+ cd Vulkan-Tools
+ mkdir build
+ cd build
+
+For 64-bit Linux and MacOS, continue with:
+
+ ../scripts/update_deps.py
+ cmake -C helper.cmake ..
+ cmake --build .
+
+For 64-bit Windows, continue with:
+
+ ..\scripts\update_deps.py --arch x64
+ cmake -A x64 -C helper.cmake ..
+ cmake --build .
+
+For 32-bit Windows, continue with:
+
+ ..\scripts\update_deps.py --arch Win32
+ cmake -A Win32 -C helper.cmake ..
+ cmake --build .
+
+Please see the more detailed build information later in this file if you have
+specific requirements for configuring and building these components.
+
+#### Notes
+
+- You may need to adjust some of the CMake options based on your platform. See
+ the platform-specific sections later in this document.
+- The `update_deps.py` script fetches and builds the dependent repositories in
+ the current directory when it is invoked. In this case, they are built in
+ the `build` directory.
+- The `build` directory is also being used to build this
+ (Vulkan-Tools) repository. But there shouldn't be any conflicts
+ inside the `build` directory between the dependent repositories and the
+ build files for this repository.
+- The `--dir` option for `update_deps.py` can be used to relocate the
+ dependent repositories to another arbitrary directory using an absolute or
+ relative path.
+- The `update_deps.py` script generates a file named `helper.cmake` and places
+ it in the same directory as the dependent repositories (`build` in this
+ case). This file contains CMake commands to set the CMake `*_INSTALL_DIR`
+ variables that are used to point to the install artifacts of the dependent
+ repositories. You can use this file with the `cmake -C` option to set these
+ variables when you generate your build files with CMake. This lets you avoid
+ entering several `*_INSTALL_DIR` variable settings on the CMake command line.
+- If using "MINGW" (Git For Windows), you may wish to run
+ `winpty update_deps.py` in order to avoid buffering all of the script's
+ "print" output until the end and to retain the ability to interrupt script
+ execution.
+- Please use `update_deps.py --help` to list additional options and read the
+ internal documentation in `update_deps.py` for further information.
+
+### Generated source code
+
+This repository contains generated source code in the `icd/generated`
+directory which is not intended to be modified directly. Instead, changes should be
+made to the corresponding generator in the `scripts` directory. The source files can
+then be regenerated using `scripts/generate_source.py`:
+
+ python3 scripts/generate_source.py PATH_TO_VULKAN_HEADERS_REGISTRY_DIR
+
+A helper CMake target `VulkanTools_generated_source` is also provided to simplify
+the invocation of `scripts/generate_source.py` from the build directory:
+
+ cmake --build . --target VulkanTools_generated_source
+
+### Build Options
+
+When generating native platform build files through CMake, several options can
+be specified to customize the build. Some of the options are binary on/off
+options, while others take a string as input. The following is a table of all
+on/off options currently supported by this repository:
+
+| Option | Platform | Default | Description |
+| ------ | -------- | ------- | ----------- |
+| BUILD_CUBE | All | `ON` | Controls whether or not the vkcube demo is built. |
+| BUILD_VULKANINFO | All | `ON` | Controls whether or not the vulkaninfo utility is built. |
+| BUILD_ICD | All | `ON` | Controls whether or not the mock ICD is built. |
+| INSTALL_ICD | All | `OFF` | Controls whether or not the mock ICD is installed as part of the install target. |
+| BUILD_WSI_XCB_SUPPORT | Linux | `ON` | Build the components with XCB support. |
+| BUILD_WSI_XLIB_SUPPORT | Linux | `ON` | Build the components with Xlib support. |
+| BUILD_WSI_WAYLAND_SUPPORT | Linux | `ON` | Build the components with Wayland support. |
+| BUILD_WSI_DIRECTFB_SUPPORT | Linux | `OFF` | Build the components with DirectFB support. |
-[](#windows-build)
+The following is a table of all string options currently supported by this repository:
+
+| Option | Platform | Default | Description |
+| ------ | -------- | ------- | ----------- |
+| VULKANINFO_BUILD_DLL_VERSIONINFO | Windows | `""` | Set the Windows specific version information for Vulkaninfo. Format is "major.minor.patch.build". |
+
+These variables should be set using the `-D` option when invoking CMake to
+generate the native platform files.
+
+### CCACHE
+
+There are 2 methods to enable CCACHE:
+
+1.) Set environment variables
+
+```bash
+# Requires CMake 3.17 (https://cmake.org/cmake/help/latest/envvar/CMAKE_LANG_COMPILER_LAUNCHER.html)
+export CMAKE_CXX_COMPILER_LAUNCHER=/usr/bin/ccache
+export CMAKE_C_COMPILER_LAUNCHER=/usr/bin/ccache
+```
+
+2.) Pass in cache variables
+
+```
+cmake ... -D CMAKE_CXX_COMPILER_LAUNCHER=/usr/bin/ccache -D CMAKE_C_COMPILER_LAUNCHER=/usr/bin/ccache
+```
+
+### EXPORT_COMPILE_COMMANDS
+
+There are 2 methods to enable exporting compile commands:
+
+1.) Set environment variables
+
+```bash
+# Requires CMake 3.17 (https://cmake.org/cmake/help/latest/envvar/CMAKE_EXPORT_COMPILE_COMMANDS.html)
+export CMAKE_EXPORT_COMPILE_COMMANDS=ON
+```
+
+2.) Pass in cache variables
+
+```
+cmake ... -D CMAKE_EXPORT_COMPILE_COMMANDS=ON
+```
+
+NOTE: Modern tools will generally enable exporting compile commands for you (e.g. VSCode).
+Also `CMAKE_EXPORT_COMPILE_COMMANDS` is implemented only by Makefile and Ninja generators. For other generators, this option is ignored.
## Building On Windows
-### Windows Build Requirements
-
-Windows 7+ with the following software packages:
-
-- Microsoft Visual Studio 2013 Update 4 Professional, VS2015 (any version), or VS2017 (any version).
-- [CMake](http://www.cmake.org/download/)
- - Tell the installer to "Add CMake to the system PATH" environment variable.
-- [Python 3](https://www.python.org/downloads)
- - Select to install the optional sub-package to add Python to the system PATH
- environment variable.
- - Ensure the `pip` module is installed (it should be by default)
- - Python3.3 or later is necessary for the Windows py.exe launcher that is used to select python3
- rather than python2 if both are installed
-- [Git](http://git-scm.com/download/win)
- - Tell the installer to allow it to be used for "Developer Prompt" as well as "Git Bash".
- - Tell the installer to treat line endings "as is" (i.e. both DOS and Unix-style line endings).
- - Install both the 32-bit and 64-bit versions, as the 64-bit installer does not install the
- 32-bit libraries and tools.
-- Notes for using [Cygwin](https://www.cygwin.com)
- - First, in a Cygwin shell:
- - `./update_external_sources.sh --no-build`
- - Then, in a Visual Studio Developer Command Prompt:
- - Ensure python3.x and CMake in are in the path
- - Run `update_external_sources.bat --no-sync`
- - Run build_windows_targets.bat cmake
+### Windows Development Environment Requirements
+
+- Windows
+ - Any Personal Computer version supported by Microsoft
+- Microsoft [Visual Studio](https://www.visualstudio.com/)
+ - Versions
+ - [2013 (update 4)](https://www.visualstudio.com/vs/older-downloads/)
+ - [2015](https://www.visualstudio.com/vs/older-downloads/)
+ - [2017](https://www.visualstudio.com/vs/downloads/)
+ - The Community Edition of each of the above versions is sufficient, as
+ well as any more capable edition.
+- [CMake 3.10.2](https://cmake.org/files/v3.10/cmake-3.10.2-win64-x64.zip) is recommended.
+ - Use the installer option to add CMake to the system PATH
+- Git Client Support
+ - [Git for Windows](http://git-scm.com/download/win) is a popular solution
+ for Windows
+ - Some IDEs (e.g., [Visual Studio](https://www.visualstudio.com/),
+ [GitHub Desktop](https://desktop.github.com/)) have integrated
+ Git client support
### Windows Build - Microsoft Visual Studio
-1. Open a Developer Command Prompt for VS201x
-2. Change directory to `Vulkan-LoaderAndValidationLayers` -- the root of the cloned git repository
-3. Run `update_external_sources.bat` -- this will download and build external components
-4. Create a `build` directory, change into that directory, and run cmake
+The general approach is to 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.
-For example, for VS2017 (generators for other versions are [specified here](#win-cmake-generators)):
+#### Windows Quick Start
- cmake -G "Visual Studio 15 2017 Win64" ..
+ cd Vulkan-Tools
+ mkdir build
+ cd build
+ cmake -A x64 -DVULKAN_HEADERS_INSTALL_DIR=absolute_path_to_install_dir
+ cmake --build .
-This will create a Windows solution file named `VULKAN.sln` in the build directory.
+The above commands instruct CMake to find and use the default Visual Studio
+installation to generate a Visual Studio solution and projects for the x64
+architecture. The second CMake command builds the Debug (default)
+configuration of the solution.
-Launch Visual Studio and open the "VULKAN.sln" solution file in 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.
-This solution copies the loader it built to each program's build directory
-to ensure that the program uses the loader built from this solution.
+See below for the details.
-#### The Update External Sources Batch File
+#### Use `CMake` to Create the Visual Studio Project Files
-Employing [optional parameters to **update_external_sources.bat**](#update-external-sources)
-can streamline repository set-up.
+Change your current directory to the top of the cloned repository directory,
+create a build directory and generate the Visual Studio project files:
-### Windows Tests and Demos
+ cd Vulkan-Tools
+ mkdir build
+ cd build
+ cmake -A x64 -DVULKAN_HEADERS_INSTALL_DIR=absolute_path_to_install_dir
-After making any changes to the repository, you should perform some quick sanity tests,
-including the run_all_tests Powershell script and the cube demo with validation enabled.
+> Note: The `..` parameter tells `cmake` the location of the top of the
+> repository. If you place your build directory someplace else, you'll need to
+> specify the location of the repository top differently.
-To run the validation test script, open a Powershell Console,
-change to the build/tests directory, and run:
+The `-A` option is used to select either the "Win32" or "x64" architecture.
-For Release builds:
+If a generator for a specific version of Visual Studio is required, you can
+specify it for Visual Studio 2015, for example, with:
- .\run_all_tests.ps1
+ 64-bit: -G "Visual Studio 14 2015 Win64"
+ 32-bit: -G "Visual Studio 14 2015"
-For Debug builds:
+See this [list](#cmake-visual-studio-generators) of other possible generators
+for Visual Studio.
- .\run_all_tests.ps1 -Debug
+When generating the project files, the absolute path to a Vulkan-Headers
+install directory must be provided. This can be done by setting the
+`VULKAN_HEADERS_INSTALL_DIR` environment variable or by setting the
+`VULKAN_HEADERS_INSTALL_DIR` CMake variable with the `-D` CMake option. In
+either case, the variable should point to the installation directory of a
+Vulkan-Headers repository built with the install target.
-This script will run the following tests:
+The above steps create a Windows solution file named
+`Vulkan-Tools.sln` in the build directory.
-- `vk_loader_validation_tests`:
- Vulkan loader handle wrapping, allocation callback, and loader/layer interface tests
-- `vk_layer_validation_tests`:
- Test Vulkan validation layers
-- `vkvalidatelayerdoc`:
- Tests that validation database is up-to-date and is synchronized with the validation source code
+At this point, you can build the solution from the command line or open the
+generated solution with Visual Studio.
-To run the Cube demo with validation in a Debug build configuration:
+#### Build the Solution From the Command Line
-- In the MSVC solution explorer, right-click on the `cube` project and select
- `Set As Startup Project`
-- Right click on cube again, select properties->Debugging->Command Arguments, change to
- `--validate`, and save
-- From the main menu, select Debug->Start Debugging, or from the toolbar click
- `Local Windows Debugger`
+While still in the build directory:
-Other demos that can be found in the build/demos directory are:
+ cmake --build .
-- `vulkaninfo`: Report GPU properties
-- `smoketest`: A "smoke" test using more complex Vulkan rendering
+to build the Debug configuration (the default), or:
-### Windows Notes
+ cmake --build . --config Release
+
+to make a Release build.
+
+#### Build the Solution With Visual Studio
+
+Launch Visual Studio and open the "Vulkan-Tools.sln" solution file in 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.
+
+#### Windows Install Target
+
+The CMake project also generates an "install" target that you can use to copy
+the primary build artifacts to a specific location using a "bin, include, lib"
+style directory structure. This may be useful for collecting the artifacts and
+providing them to another project that is dependent on them.
+
+The default location is `$CMAKE_BINARY_DIR\install`, but can be changed with
+the `CMAKE_INSTALL_PREFIX` variable when first generating the project build
+files with CMake.
+
+You can build the install target from the command line with:
+
+ cmake --build . --config Release --target install
+
+or build the `INSTALL` target from the Visual Studio solution explorer.
+
+#### Using a Loader Built from a Repository
+
+If you do need to build and use your own loader, build the Vulkan-Loader
+repository with the install target and modify your CMake invocation to add the
+location of the loader's install directory:
+
+ cmake -A x64 -DVULKAN_HEADERS_INSTALL_DIR=absolute_path_to_install_dir \
+ -DVULKAN_LOADER_INSTALL_DIR=absolute_path_to_install_dir ..
+
+#### Using glslang Built from a Repository
-[](#win-cmake-generators)
+If you do need to build and use your own glslang, build the glslang repository
+with the install target and modify your CMake invocation to add the location
+of the glslang's install directory:
+
+ cmake -A x64 -DVULKAN_HEADERS_INSTALL_DIR=absolute_path_to_install_dir \
+ -DGLSLANG_INSTALL_DIR=absolute_path_to_install_dir ..
+
+### Windows Notes
#### CMake Visual Studio Generators
-The above example used Visual Studio 2017, and specified its generator as "Visual Studio 15 2017 Win64".
-The chosen generator should match your Visual Studio version. Appropriate Visual Studio generators include:
+The chosen generator should match one of the Visual Studio versions that you
+have installed. Generator strings that correspond to versions of Visual Studio
+include:
| Build Platform | 64-bit Generator | 32-bit Generator |
|------------------------------|-------------------------------|-------------------------|
| Microsoft Visual Studio 2015 | "Visual Studio 14 2015 Win64" | "Visual Studio 14 2015" |
| Microsoft Visual Studio 2017 | "Visual Studio 15 2017 Win64" | "Visual Studio 15 2017" |
-#### The Vulkan Loader Library
-
-Vulkan programs must be able to find and use the vulkan-1.dll library.
-While several of the test and demo projects in the Windows solution set this up automatically, doing so manually may be necessary for custom projects or solutions.
-Make sure the library is either installed in the C:\Windows\System32 folder, or that the PATH environment variable includes the folder where the library resides.
-
-To run Vulkan programs you must tell the Vulkan Loader where to find the libraries.
-This is described in a `LoaderAndLayerInterface` document in the `loader` folder in this repository.
-This describes both how ICDs and layers should be properly packaged, and how developers can point to ICDs and layers within their builds.

## Building On Linux
### Linux Build Requirements
-This repository has been built and tested on the two most recent Ubuntu LTS versions.
-Currently, the oldest supported version is Ubuntu 14.04, meaning that the minimum supported compiler versions are GCC 4.8.2 and Clang 3.4, although earlier versions may work.
-It should be straightforward to adapt this repository to other Linux distributions.
+This repository has been built and tested on the two most recent Ubuntu LTS
+versions. Currently, the oldest supported version is Ubuntu 16.04, meaning
+that the minimum officially supported C++11 compiler version is GCC 5.4.0,
+although earlier versions may work. It should be straightforward to adapt this
+repository to other Linux distributions.
-**Required Package List:**
+[CMake 3.10.2](https://cmake.org/files/v3.10/cmake-3.10.2-Linux-x86_64.tar.gz) is recommended.
- sudo apt-get install git cmake build-essential libx11-xcb-dev libxkbcommon-dev libmirclient-dev libwayland-dev libxrandr-dev
+#### Required Package List
+
+ sudo apt-get install git cmake build-essential libx11-xcb-dev \
+ libxkbcommon-dev libwayland-dev libxrandr-dev wayland-protocols
### Linux Build
-Example debug build (Note that the update\_external\_sources script used below builds external tools into predefined locations.
-See **Loader and Validation Layer Dependencies** for more information and other options):
+The general approach is to run CMake to generate make files. Then either run
+CMake with the `--build` option or `make` to build from the command line.
-1. In a Linux terminal, `cd Vulkan-LoaderAndValidationLayers` -- the root of the
- cloned git repository
-2. Execute `./update_external_sources.sh` -- this will download and build external components
-3. Create a `build` directory, change into that directory, and run cmake:
+#### Linux Quick Start
- ```script
- mkdir build
- cd build
- cmake -DCMAKE_BUILD_TYPE=Debug ..
- ```
+ cd Vulkan-Tools
+ mkdir build
+ cd build
+ cmake -DVULKAN_HEADERS_INSTALL_DIR=absolute_path_to_install_dir ..
+ make
-4. Change into the newly-created build directory
-5. Run `make -j8` to begin the build
+See below for the details.
-If your build system supports ccache, you can enable that via CMake option `-DUSE_CCACHE=On`
+#### Use CMake to Create the Make Files
-#### The Update External Sources script
+Change your current directory to the top of the cloned repository directory,
+create a build directory and generate the make files.
-Employing [optional parameters to **update_external_sources.sh**](#update-external-sources) can streamline repository set-up.
+ cd Vulkan-Tools
+ mkdir build
+ cd build
+ cmake -DCMAKE_BUILD_TYPE=Debug \
+ -DVULKAN_HEADERS_INSTALL_DIR=absolute_path_to_install_dir \
+ -DCMAKE_INSTALL_PREFIX=install ..
-#### Using the new loader and layers
+> Note: The `..` parameter tells `cmake` the location of the top of the
+> repository. If you place your `build` directory someplace else, you'll need
+> to specify the location of the repository top differently.
- export LD_LIBRARY_PATH=<path to your repository root>/build/loader
- export VK_LAYER_PATH=<path to your repository root>/build/layers
+Use `-DCMAKE_BUILD_TYPE` to specify a Debug or Release build.
-You can run the `vulkaninfo` application to see which driver, loader and layers are being used.
+When generating the project files, the absolute path to a Vulkan-Headers
+install directory must be provided. This can be done by setting the
+`VULKAN_HEADERS_INSTALL_DIR` environment variable or by setting the
+`VULKAN_HEADERS_INSTALL_DIR` CMake variable with the `-D` CMake option. In
+either case, the variable should point to the installation directory of a
+Vulkan-Headers repository built with the install target.
-The `LoaderAndLayerInterface` document in the `loader` folder in this repository
-is a specification that describes both how ICDs and layers should be properly packaged,
-and how developers can point to ICDs and layers within their builds.
+> Note: For Linux, the default value for `CMAKE_INSTALL_PREFIX` is
+> `/usr/local`, which would be used if you do not specify
+> `CMAKE_INSTALL_PREFIX`. In this case, you may need to use `sudo` to install
+> to system directories later when you run `make install`.
-### WSI Support Build Options
+#### Build the Project
-By default, the Vulkan Loader and Validation Layers are built with support for all 4 Vulkan-defined WSI display servers: Xcb, Xlib, Wayland, and Mir.
-It is recommended to build the repository components with support for these display servers to maximize their usability across Linux platforms.
-If it is necessary to build these modules without support for one of the display servers, the appropriate CMake option of the form `BUILD_WSI_xxx_SUPPORT` can be set to `OFF`.
-See the top-level CMakeLists.txt file for more info.
+You can just run `make` to begin the build.
-### Linux Install to System Directories
+To speed up the build on a multi-core machine, use the `-j` option for `make`
+to specify the number of cores to use for the build. For example:
-Installing the files resulting from your build to the systems directories is optional since environment variables can usually be used instead to locate the binaries.
-There are also risks with interfering with binaries installed by packages.
-If you are certain that you would like to install your binaries to system directories, you can proceed with these instructions.
+ make -j4
-Assuming that you've built the code as described above and the current directory is still `build`, you can execute:
+You can also use
- sudo make install
+ cmake --build .
+
+If your build system supports ccache, you can enable that via CMake option `-DUSE_CCACHE=On`
-This command installs files to:
+### Linux Notes
-- `/usr/local/include/vulkan`: Vulkan include files
-- `/usr/local/lib`: Vulkan loader and layers shared objects
-- `/usr/local/bin`: vulkaninfo application
-- `/usr/local/etc/vulkan/explicit_layer.d`: Layer JSON files
+#### WSI Support Build Options
-You may need to run `ldconfig` in order to refresh the system loader search cache on some Linux systems.
+By default, the repository components are built with support for the
+Vulkan-defined WSI display servers: Xcb, Xlib, and Wayland. It is recommended
+to build the repository components with support for these display servers to
+maximize their usability across Linux platforms. If it is necessary to build
+these modules without support for one of the display servers, the appropriate
+CMake option of the form `BUILD_WSI_xxx_SUPPORT` can be set to `OFF`.
-You can further customize the installation location by setting additional CMake variables to override their defaults.
-For example, if you would like to install to `/tmp/build` instead of `/usr/local`, on your CMake command line specify:
+Note vulkaninfo currently only supports Xcb and Xlib WSI display servers. See
+the CMakeLists.txt file in `Vulkan-Tools/vulkaninfo` for more info.
- -DCMAKE_INSTALL_PREFIX=/tmp/build
- -DDEST_DIR=/tmp/build
+You can select which WSI subsystem is used to execute the vkcube applications
+using a CMake option called CUBE_WSI_SELECTION. Supported options are XCB
+(default), XLIB, and WAYLAND. Note that you must build using the corresponding
+BUILD_WSI_*_SUPPORT enabled at the base repository level. For instance,
+creating a build that will use Xlib when running the vkcube demos, your CMake
+command line might look like:
-Then run `make install` as before. The install step places the files in `/tmp/build`.
+ cmake -DCMAKE_BUILD_TYPE=Debug -DCUBE_WSI_SELECTION=XLIB ..
-Using the `CMAKE_INSTALL_PREFIX` to customize the install location also modifies
-the loader search paths to include searching for layers in the specified install location.
-In this example, setting `CMAKE_INSTALL_PREFIX` to `/tmp/build` causes the loader to search
-`/tmp/build/etc/vulkan/explicit_layer.d` and `/tmp/build/share/vulkan/explicit_layer.d`
-for the layer JSON files.
-The loader also searches the "standard" system locations of `/etc/vulkan/explicit_layer.d` and
-`/usr/share/vulkan/explicit_layer.d` after searching the two locations under `/tmp/build`.
+#### Linux Install to System Directories
-You can further customize the installation directories by using the CMake variables
-`CMAKE_INSTALL_SYSCONFDIR` to rename the `etc` directory and `CMAKE_INSTALL_DATADIR`
-to rename the `share` directory.
+Installing the files resulting from your build to the systems directories is
+optional since environment variables can usually be used instead to locate the
+binaries. There are also risks with interfering with binaries installed by
+packages. If you are certain that you would like to install your binaries to
+system directories, you can proceed with these instructions.
-See the CMake documentation for more details on using these variables
-to further customize your installation.
+Assuming that you've built the code as described above and the current
+directory is still `build`, you can execute:
-Also see the `LoaderAndLayerInterface` document in the `loader` folder in this
-repository for more information about loader operation.
+ sudo make install
-Note that some executables in this repository (e.g., `cube`) use the "rpath" linker directive to
-load the Vulkan loader from the build directory, `build` in this example.
-This means that even after installing the loader to the system directories, these executables still
-use the loader from the build directory.
+This command installs files to `/usr/local` if no `CMAKE_INSTALL_PREFIX` is
+specified when creating the build files with CMake.
-### Linux Uninstall
+You may need to run `ldconfig` in order to refresh the system loader search
+cache on some Linux systems.
-To uninstall the files from the system directories, you can execute:
+You can further customize the installation location by setting additional
+CMake variables to override their defaults. For example, if you would like to
+install to `/tmp/build` instead of `/usr/local`, on your CMake command line
+specify:
- sudo make uninstall
+ -DCMAKE_INSTALL_PREFIX=/tmp/build
-### Linux Tests and Demos
+Then run `make install` as before. The install step places the files in
+`/tmp/build`. This may be useful for collecting the artifacts and providing
+them to another project that is dependent on them.
-After making any changes to the repository, you should perform some quick sanity tests, including
-the run_all_tests shell script and the cube demo with validation enabled.
+Note: The Mock ICD is not installed by default since it is a "null" driver
+that does not render anything and is used for testing purposes. Installing it
+to system directories may cause some applications to discover and use this
+driver instead of other full drivers installed on the system. If you really
+want to install this null driver, use:
-To run the **validation test script**, in a terminal change to the build/tests directory and run:
+ -DINSTALL_ICD=ON
- VK_LAYER_PATH=../layers ./run_all_tests.sh
+See the CMake documentation for more details on using these variables to
+further customize your installation.
-This script will run the following tests:
+Also see the `LoaderAndLayerInterface` document in the `loader` folder of the
+Vulkan-Loader repository for more information about loader and layer
+operation.
-- `vk_loader_validation_tests`: Tests Vulkan Loader handle wrapping
-- `vk_layer_validation_tests`: Test Vulkan validation layers
-- `vkvalidatelayerdoc`: Tests that validation database is in up-to-date and in synchronization with
- the validation source code
+#### Linux Uninstall
-To run the **Cube demo** with validation, in a terminal change to the `build/demos`
-directory and run:
+To uninstall the files from the system directories, you can execute:
- VK_LAYER_PATH=../layers ./cube --validate
+ sudo make uninstall
-Other demos that can be found in the `build/demos` directory are:
+### Linux Tests
-- `vulkaninfo`: report GPU properties
-- `smoketest`: A "smoke" test using more complex Vulkan rendering
+After making any changes to the repository, you should perform some quick
+sanity tests, such as running the vkcube demo with validation enabled.
-You can select which WSI subsystem is used to build the demos using a CMake option
-called DEMOS_WSI_SELECTION.
-Supported options are XCB (default), XLIB, WAYLAND, and MIR.
-Note that you must build using the corresponding BUILD_WSI_*_SUPPORT enabled at the
-base repository level (all SUPPORT options are ON by default).
-For instance, creating a build that will use Xlib to build the demos,
-your CMake command line might look like:
+To run the **vkcube application** with validation, in a terminal change to the
+`build/cube` directory and run:
- cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=Debug -DDEMOS_WSI_SELECTION=XLIB
+ VK_LAYER_PATH=../path/to/validation/layers ./vkcube --validate
-### Linux Notes
+If you have an SDK installed and have run the setup script to set the
+`VULKAN_SDK` environment variable, it may be unnecessary to specify a
+`VK_LAYER_PATH`.

### Android Build
-There are two options for building the Android layers.
-Either using the SPIRV tools provided as part of the Android NDK, or using upstream sources.
-To build with SPIRV tools from the NDK, remove the build-android/third_party directory created by
-running update_external_sources_android.sh, (or avoid running update_external_sources_android.sh).
-Use the following script to build everything in the repository for Android, including validation
-layers, tests, demos, and APK packaging: This script does retrieve and use the upstream SPRIV tools.
+Use the following script to build the vkcube demo for Android:
cd build-android
./build_all.sh
-Resulting validation layer binaries will be in build-android/libs.
-Test and demo APKs can be installed on production devices with:
+The APK can be installed on production devices with:
./install_all.sh [-s <serial number>]
-Note that there are no equivalent scripts on Windows yet, that work needs to be completed.
-The following per platform commands can be used for layer only builds:
-
-#### Linux and OSX
-
-Follow the setup steps for Linux or OSX above, then from your terminal:
-
- cd build-android
- ./update_external_sources_android.sh --no-build
- ./android-generate.sh
- ndk-build -j4
+Note that there are no equivalent scripts on Windows yet, that work needs to
+be completed.
-#### Windows
+### Run vkcube
-Follow the setup steps for Windows above, then from Developer Command Prompt for VS2013:
+Use the following command to run vkcube for Android:
- cd build-android
- update_external_sources_android.bat
- android-generate.bat
- ndk-build
+ adb shell am start com.example.VkCube/android.app.NativeActivity
-### Android Tests and Demos
+## Building on MacOS
-After making any changes to the repository you should perform some quick sanity tests,
-including the layer validation tests and the cube and smoke demos with validation enabled.
+### MacOS Build Requirements
-#### Run Layer Validation Tests
+Tested on OSX version 10.12
-Use the following steps to build, install, and run the layer validation tests for Android:
+NOTE: To force the OSX version set the environment variable [MACOSX_DEPLOYMENT_TARGET](https://cmake.org/cmake/help/latest/envvar/MACOSX_DEPLOYMENT_TARGET.html) when building VVL and it's dependencies.
- cd build-android
- ./build_all.sh
- adb install -r bin/VulkanLayerValidationTests.apk
- adb shell am start com.example.VulkanLayerValidationTests/android.app.NativeActivity
+Setup Homebrew and components
-Alternatively, you can use the test_APK script to install and run the layer validation tests:
+- Ensure Homebrew is at the beginning of your PATH:
- test_APK.sh -s <serial number> -p <plaform name> -f <gtest_filter>
+ export PATH=/usr/local/bin:$PATH
-#### Run Cube and Smoke with Validation
+- Add packages with the following (may need refinement)
-Use the following steps to build, install, and run Cube and Smoke for Android:
+ brew install python python3 git
- cd build-android
- ./build_all.sh
- adb install -r ../demos/android/cube/bin/cube.apk
- adb shell am start com.example.Cube/android.app.NativeActivity
+### Clone the Repository
-To build, install, and run Cube with validation layers,
-first build layers using steps above, then run:
+Clone the Vulkan-Tools repository as defined above in the [Download the Repository](#download-the-repository)
+section.
- cd build-android
- ./build_all.sh
- adb install -r ../demos/android/cube-with-layers/bin/cube-with-layers.apk
+### Get the External Libraries
-##### Run without validation enabled
+[MoltenVK](https://github.com/KhronosGroup/MoltenVK) Library
- adb shell am start com.example.CubeWithLayers/android.app.NativeActivity
+- Building the vkcube and vulkaninfo applications require linking to the
+ MoltenVK Library (libMoltenVK.dylib)
+ - The following option should be used on the cmake command line to specify a
+ vulkan loader library: MOLTENVK_REPO_ROOT=/absolute_path_to/MoltenVK
+ making sure to specify an absolute path, like so: cmake
+ -DMOLTENVK_REPO_ROOT=/absolute_path_to/MoltenVK ....
-##### Run with validation enabled
+Vulkan Loader Library
- adb shell am start -a android.intent.action.MAIN -c android-intent.category.LAUNCH -n com.example.CubeWithLayers/android.app.NativeActivity --es args "--validate"
+- Building the vkcube and vulkaninfo applications require linking to the Vulkan
+ Loader Library (libvulkan.1.dylib)
+ - The following option should be used on the cmake command line to specify a
+ vulkan loader library:
+ VULKAN_LOADER_INSTALL_DIR=/absolute_path_to/Vulkan-Loader_install_dir
+ making sure to specify an absolute path.
-vkjson_info for Android is built as an executable for devices with root access.
+### MacOS build
-To use, simply push it to the device and run it:
+#### CMake Generators
- ./build_all.sh
- adb push obj/local/<abi>/vkjson_info /data/tmp/
- adb shell /data/tmp/vkjson_info
+This repository uses CMake to generate build or project files that are then
+used to build the repository. The CMake generators explicitly supported in
+this repository are:
-The resulting json file will be found in:
+- Unix Makefiles
+- Xcode
- /sdcard/Android/<device_name>.json
+#### Building with the Unix Makefiles Generator
-To build, install, and run the Smoke demo for Android, run the following, and any prompts that come back from the script:
+This generator is the default generator, so all that is needed for a debug
+build is:
- ./update_external_sources.sh --glslang
- cd demos/smoke/android
- export ANDROID_SDK_HOME=<path to Android/Sdk>
- export ANDROID_NDK_HOME=<path to Android/Sdk/ndk-bundle>
- ./build-and-install
- adb shell am start -a android.intent.action.MAIN -c android-intent.category.LAUNCH -n com.example.Smoke/android.app.NativeActivity --es args "--validate"

+ -DMOLTENVK_REPO_ROOT=/absolute_path_to/MoltenVK \
+ -DCMAKE_INSTALL_PREFIX=install ..
+ make
-## Ninja Builds - All Platforms
+To speed up the build on a multi-core machine, use the `-j` option for `make`
+to specify the number of cores to use for the build. For example:
-The [Qt Creator IDE](https://qt.io/download-open-source/#section-2) can open a root CMakeList.txt
-as a project directly, and it provides tools within Creator to configure and generate Vulkan SDK
-build files for one to many targets concurrently.
-Alternatively, when invoking CMake, use the `-G Codeblocks` Ninja option to generate Ninja build
-files to be used as project files for QtCreator
+ make -j4
-- Follow the steps defined elsewhere for the OS using the update\_external\_sources script or as
- shown in **Loader and Validation Layer Dependencies** below
-- Open, configure, and build the glslang CMakeList.txt files. Note that building the glslang
- project will provide access to spirv-tools and spirv-headers
-- Then do the same with the Vulkan-LoaderAndValidationLayers CMakeList.txt file
-- In order to debug with QtCreator, a
- [Microsoft WDK: eg WDK 10](http://go.microsoft.com/fwlink/p/?LinkId=526733) is required.
+You can now run the demo applications from the command line:
-Note that installing the WDK breaks the MSVC vcvarsall.bat build scripts provided by MSVC, requiring that the LIB, INCLUDE, and PATHenv variables be set to the WDK paths by some other means
+ open cube/vkcube.app
+ open cube/vkcubepp.app
-[](#update-external-sources)
+Or you can locate them from `Finder` and launch them from there.
-## Update External Sources Optional Parameters
+##### The Install Target and RPATH
-This script will default to building 64-bit _and_ 32-bit versions of debug _and_ release
-configurations, which can take a substantial amount of time.
-However, it supports the following options to select a particular build configuration which can
-reduce the time needed for repository set-up:
+The applications you just built are "bundled applications", but the
+executables are using the `RPATH` mechanism to locate runtime dependencies
+that are still in your build tree.
-| Command Line Option | Function |
-|----------------------|----------------------------------------------|
-| --32 | Build 32-bit targets only |
-| --64 | Build 64-bit targets only |
-| --release | Perform release builds only |
-| --debug | Perform debug builds only |
-| --no-build | Sync without building targets |
-| --no-sync | Skip repository sync step |
+To see this, run this command from your `build` directory:
-For example, to target a Windows 64-bit debug development configuration, invoke the batch file as follows:
+ otool -l cube/cube.app/Contents/MacOS/vkcube
-`update_external_sources.bat --64 --debug`
+and note that the `vkcube` executable contains loader commands:
-Similarly, invoking the same configuration for Linux would be:
+- `LC_LOAD_DYLIB` to load `libvulkan.1.dylib` via an `@rpath`
+- `LC_RPATH` that contains an absolute path to the build location of the Vulkan loader
-`update_external_sources.sh --64 --debug`
+This makes the bundled application "non-transportable", meaning that it won't
+run unless the Vulkan loader is on that specific absolute path. This is useful
+for debugging the loader or other components built in this repository, but not
+if you want to move the application to another machine or remove your build
+tree.
-## Loader and Validation Layer Dependencies
+To address this problem, run:
-The glslang repository is required to build and run Loader and Validation Layer components.
-It is not a git sub-module of Vulkan-LoaderAndValidationLayers but Vulkan-LoaderAndValidationLayers
-is linked to a specific revision of glslang.
-This can be automatically cloned and built to predefined locations with the
-`update_external_sources` scripts.
-If a custom configuration is required, do the following steps:
+ make install
-1) clone the repository:
+This step copies the bundled applications to the location specified by
+CMAKE_INSTALL_PREFIX and "cleans up" the `RPATH` to remove any external
+references and performs other bundle fix-ups. After running `make install`,
+run the `otool` command again from the `build/install` directory and note:
- `git clone https://github.com/KhronosGroup/glslang.git`
+- `LC_LOAD_DYLIB` is now `@executable_path/../MacOS/libvulkan.1.dylib`
+- `LC_RPATH` is no longer present
-2) checkout the correct version of the tree based on the contents of the
-glslang\_revision file at the root of the Vulkan-LoaderAndValidationLayers tree
-(do the same anytime that Vulkan-LoaderAndValidationLayers is updated from remote)
+The "bundle fix-up" operation also puts a copy of the Vulkan loader into the
+bundle, making the bundle completely self-contained and self-referencing.
- - On Windows
+##### The vulkaninfo Application
- ```script
- git checkout < [path to Vulkan-LoaderAndValidationLayers]\glslang_revision [in glslang repo]
- ```
+There is also a `vulkaninfo` application that you can run from the command line:
- - Non Windows
+ vulkaninfo/vulkaninfo
- ```script
- git checkout `cat [path to Vulkan-LoaderAndValidationLayers]\glslang_revision` [in glslang repo]
- ```
+If you run this from the build directory, vulkaninfo's RPATH is already
+set to point to the Vulkan loader in the build tree, so it has no trouble
+finding it. But the loader will not find the MoltenVK driver and you'll see a
+message about an incompatible driver. To remedy this:
-3) Configure the glslang source tree with CMake and build it with your IDE of choice
+ VK_ICD_FILENAMES=<path-to>/MoltenVK/Package/Latest/MoltenVK/macOS/MoltenVK_icd.json vulkaninfo/vulkaninfo
-4) Enable the `CUSTOM_GLSLANG_BIN_PATH` and `CUSTOM_SPIRV_TOOLS_BIN_PATH` options in the Vulkan-LoaderAndValidationLayers CMake configuration and point the `GLSLANG_BINARY_PATH` and `SPIRV_TOOLS_BINARY_PATH` variables to the correct location
+If you run `vulkaninfo` from the install directory, the `RPATH` in the
+`vulkaninfo` application got removed and the OS needs extra help to locate
+the Vulkan loader:
-5) If building on Windows with MSVC, set `DISABLE_BUILDTGT_DIR_DECORATION` to _On_.
- If building on Windows, but without MSVC set `DISABLE_BUILD_PATH_DECORATION` to _On_
+ DYLD_LIBRARY_PATH=<path-to>/Vulkan-Loader/loader VK_ICD_FILENAMES=<path-to>/MoltenVK/Package/Latest/MoltenVK/macOS/MoltenVK_icd.json vulkaninfo/vulkaninfo
-## Optional software packages

-- [Cygwin for windows](https://www.cygwin.com/)
- - Cygwin provides some Linux-like tools, which can be valuable for working with the repository,
- such as the BASH shell and git packages
