### Windows Build - Microsoft Visual Studio
4. Create a `build` directory, change into that directory, and run cmake
For example, for VS2017 (generators for other versions are [specified here](#win-cmake-generators)):
-```
- cmake -G "Visual Studio 15 2017 Win64" ..
-```
- This will create a Windows solution file named `VULKAN.sln` in the build directory.
+
+ cmake -G "Visual Studio 15 2017 Win64" ..
+
+This will create a Windows solution file named `VULKAN.sln` in the build directory.
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.

### Windows Notes
-<a name="win-cmake-generators"/>
+[](#win-cmake-generators)
-**Cmake Visual Studio Generators**
+#### 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:
| 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**
+#### 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.
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
It should be straightforward to adapt this repository to other Linux distributions.
**Required Package List:**
-```
-sudo apt-get install git cmake build-essential libx11-xcb-dev libxkbcommon-dev libmirclient-dev libwayland-dev libxrandr-dev
-```
+
+ sudo apt-get install git cmake build-essential libx11-xcb-dev libxkbcommon-dev libmirclient-dev libwayland-dev libxrandr-dev
### 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):
-1. In a Linux terminal, `cd Vulkan-LoaderAndValidationLayers` -- the root of the cloned git repository
+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:
-```
-mkdir build
-cd build
-cmake -DCMAKE_BUILD_TYPE=Debug ..
-```
+
+ ```script
+ mkdir build
+ cd build
+ cmake -DCMAKE_BUILD_TYPE=Debug ..
+ ```
+
4. Change into the newly-created build directory
5. Run `make -j8` to begin the build
-If your build system supports ccache, you can enable that via cmake option `-DUSE_CCACHE=On`
+If your build system supports ccache, you can enable that via CMake option `-DUSE_CCACHE=On`

+#### The Update External Sources script
-**The Update External Sources script**
Employing [optional parameters to **update_external_sources.sh**](#update-external-sources) can streamline repository set-up.
-**Using the new loader and layers:**
-```
-export LD_LIBRARY_PATH=<path to your repository root>/build/loader
-export VK_LAYER_PATH=<path to your repository root>/build/layers
-```

### WSI Support Build Options
Assuming that you've built the code as described above and the current directory is still `build`, you can execute:
-```
-sudo make install
-```
+ sudo make install
+
This command installs files to:
-* `/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
+- `/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
You may need to run `ldconfig` in order to refresh the system loader search cache on some Linux systems.
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:
-```
--DCMAKE_INSTALL_PREFIX=/tmp/build
--DDEST_DIR=/tmp/build
-```
+ -DCMAKE_INSTALL_PREFIX=/tmp/build
+ -DDEST_DIR=/tmp/build
Then run `make install` as before. The install step places the files in `/tmp/build`.
-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`.

-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.

### Linux Notes
#### Linux 32-bit support
Usage of this repository's contents in 32-bit Linux environments is not officially supported.
-However, since this repository is supported on 32-bit Windows, these modules should generally work on 32-bit Linux.
+However, since this repository is supported on 32-bit Windows,
+these modules should generally work on 32-bit Linux.
Here are some notes for building 32-bit targets on a 64-bit Ubuntu "reference" platform:
Set up your environment for building 32-bit targets:
-```
-export ASFLAGS=--32
-export CFLAGS=-m32
-export CXXFLAGS=-m32
-export PKG_CONFIG_LIBDIR=/usr/lib/i386-linux-gnu
-```
+ export ASFLAGS=--32
+ export CFLAGS=-m32
+ export CXXFLAGS=-m32
+ export PKG_CONFIG_LIBDIR=/usr/lib/i386-linux-gnu
Again, your PKG_CONFIG configuration may be different, depending on your distribution.
-If the libraries in the `external` directory have already been built for 64-bit targets, delete or "clean" this directory and rebuild it with the above settings using the `update_external_sources` shell script.
-This is required because the libraries in `external` must be built for 32-bit in order to be usable by the rest of the components in the repository.

### 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.

## Ninja Builds - All Platforms
-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
-- 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

## Loader and Validation Layer Dependencies
+
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:
1) clone the repository:
`git clone https://github.com/KhronosGroup/glslang.git`
-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)
