Build Instructions

This project fully supports Linux and Windows today. Support for Android is TBD.

Git the Bits

You should have access to the Khronos GitHub repository at https://github.com/KhronosGroup/. The preferred work flow is to clone the repo, create a branch, push branch to GitHub and then issue a merge request to integrate that work back into the repo.

Note: If you are doing ICD (driver) development, please make sure to look at documentation in the ICD Loader and the Sample Driver.

Linux System Requirements

Ubuntu 14.04.3 LTS, 14.10, 15.04 and 15.10 have been used with the sample driver.

These packages are used for building and running the samples.

sudo apt-get install git subversion cmake libgl1-mesa-dev freeglut3-dev libglm-dev qt5-default libpciaccess-dev libpthread-stubs0-dev libudev-dev bison graphviz libpng-dev
sudo apt-get build-dep mesa

The sample driver uses DRI3 for its window system interface. That requires extra configuration of Ubuntu systems.

Ubuntu 14.04.3 LTS support of DRI 3

Ubuntu 14.04.3 LTS does not ship a xserver-xorg-video-intel package with supported DRI 3 on intel graphics. The xserver-xorg-video-intel package can be built from source with DRI 3 enabled. Use the following commands to enable DRI3 on ubuntu 14.04.3 LTS.

Ubuntu 14.10 support of DRI 3

Warning: Recent versions of 14.10 have REMOVED DRI 3. Version: 2:2.99.914-1~exp1ubuntu4.1 is known to work. To see status of this package:

dpkg -s xserver-xorg-video-intel

Note: Version 2:2.99.914-1~exp1ubuntu4.2 does not work anymore. To install the working driver from launchpadlibrarian.net:

Remove the current driver:

sudo apt-get purge xserver-xorg-video-intel

Download the old driver:

wget http://launchpadlibrarian.net/189418339/xserver-xorg-video-intel_2.99.914-1%7Eexp1ubuntu4.1_amd64.deb

Install the driver:

sudo dpkg -i xserver-xorg-video-intel_2.99.914-1~exp1ubuntu4.1_amd64.deb

Pin the package to prevent updates

sudo bash -c "echo $'Package: xserver-xorg-video-intel\nPin: version 2:2.99.914-1~exp1ubuntu4.1\nPin-Priority: 1001' > /etc/apt/preferences.d/xserver-xorg-video-intel"

Either restart Ubuntu or just X11.

Ubuntu 15.04 support of DRI 3

Ubuntu 15.04 has never shipped a xserver-xorg-video-intel package with supported DRI 3 on intel graphics. The xserver-xorg-video-intel package can be built from source with DRI 3 enabled. Use the following commands to enable DRI3 on ubuntu 15.04.

Clone the repository

To create your local git repository:

mkdir YOUR_DEV_DIRECTORY  # it's called Vulkan-LoaderAndValidationLayers on Github, but the name doesn't matter
cd YOUR_DEV_DIRECTORY
git clone -o khronos https://github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers .
# Or substitute the URL from your forked repo for https://github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers above.

Linux Build

The sample driver uses cmake and should work with the usual cmake options and utilities. The standard build process builds the icd, the icd loader and all the tests.

Example debug build:

cd YOUR_DEV_DIRECTORY  # cd to the root of the Vulkan-LoaderAndValidationLayers git repository
./update_external_sources.sh  # Fetches and builds glslang, llvm, LunarGLASS, and spirv-tools
cmake -H. -Bdbuild -DCMAKE_BUILD_TYPE=Debug
cd dbuild
make

To run Vulkan programs you must tell the icd loader where to find the libraries. This is described in a specification in the Khronos documentation Git repository. See the file: https://github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers/blob/sdk-1.0.3/loader/LoaderAndLayerInterface.md#vulkan-installable-client-driver-interface-with-the-loader

This specification describes both how ICDs and layers should be properly packaged, and how developers can point to ICDs and layers within their builds.

Validation Test

The test executables can be found in the dbuild/tests directory. The tests use the Google gtest infrastructure. Tests available so far:

vk_layer_validation_tests: Test Vulkan layers.

There are also a few shell and Python scripts that run test collections (eg, run_all_tests.sh).

Linux Demos

The demos executables can be found in the dbuild/demos directory. The demos use DRI 3 to render directly onto window surfaces.

vulkaninfo: report GPU properties
tri: a textured triangle
cube: a textured spinning cube

Windows System Requirements

Windows 7+ with additional required software packages:

Microsoft Visual Studio 2013 Professional. Note: it is possible that lesser/older versions may work, but that has not been tested.
CMake (from http://www.cmake.org/download/). Notes:
- Tell the installer to “Add CMake to the system PATH” environment variable.
Python 3 (from https://www.python.org/downloads). Notes:
- Select to install the optional sub-package to add Python to the system PATH environment variable.
- Need python3.3 or later to get the Windows py.exe launcher that is used to get python3 rather than python2 if both are installed on Windows
Git (from http://git-scm.com/download/win).
- Note: If you use Cygwin, you can normally use Cygwin's “git.exe”. However, in order to use the “update_external_sources.bat” script, you must have this version.
- 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 each a 32-bit and a 64-bit version, as the 64-bit installer does not install the 32-bit libraries and tools.
glslang is required for demos and tests.
- You can download and configure it (in a peer directory) here: https://github.com/KhronosGroup/glslang/blob/master/README.md
- A windows batch file has been included that will pull and build the correct version. Run it from Developer Command Prompt for VS2013 like so:
  - update_external_sources.bat --build-glslang

Optional software packages:

Cygwin (from https://www.cygwin.com/). Notes:
- Cygwin provides some Linux-like tools, which are valuable for obtaining the source code, and running CMake. Especially valuable are the BASH shell and git packages.
- If you don‘t want to use Cygwin, there are other shells and environments that can be used. You can also use a Git package that doesn’t come from Cygwin.

Windows Build

Cygwin is used in order to obtain a local copy of the Git repository, and to run the CMake command that creates Visual Studio files. Visual Studio is used to build the software, and will re-run CMake as appropriate.

Example debug x64 build (e.g. in a “Developer Command Prompt for VS2013” window):

cd YOUR_DEV_DIRECTORY  # cd to the root of the Vulkan-LoaderAndValidationLayers git repository
update_external_sources.bat --all
build_windows_targets.bat

At this point, you can use Windows Explorer to launch Visual Studio by double-clicking on the “VULKAN.sln” file in the \build folder. Once Visual Studio comes up, you can select “Debug” or “Release” from a drop-down list. You can start a build with either the menu (Build->Build Solution), or a keyboard shortcut (Ctrl+Shift+B). As part of the build process, Python scripts will create additional Visual Studio files and projects, along with additional source files. All of these auto-generated files are under the “build” folder.

Vulkan programs must be able to find and use the vulkan-1.dll libary. Make sure it is either installed in the C:\Windows\System32 folder, or the PATH environment variable includes the folder that it is located in.

This specification describes both how ICDs and layers should be properly packaged, and how developers can point to ICDs and layers within their builds.

Windows 64-bit Installation Notes

If you plan on creating a Windows Install file (done in the windowsRuntimeInstaller sub-directory) you will need to build for both 32-bit and 64-bit Windows since both versions of EXEs and DLLs exist simultaneously on Windows 64.

To do this, simply create and build the release versions of each target:

cd LoaderAndTools  # cd to the root of the Vulkan git repository
update_external_sources.bat --all
mkdir build
cd build
cmake -G "Visual Studio 12 Win64" ..
msbuild ALL_BUILD.vcxproj /p:Platform=x64 /p:Configuration=Release
mkdir build32
cd build32
cmake -G "Visual Studio 12" ..
msbuild ALL_BUILD.vcxproj /p:Platform=x86 /p:Configuration=Release
