# How to Use Vulkan SDK with AppVeyor and Travis CI?
AppVeyor and Travis CI are popular, free web services that provide continuous integration style build and testing environments for open source projects - for Windows and Linux, respectively. They are relatively easy to setup if your project is self-contained, but can be a little bit tricky if you need to install some additional dependencies. Today I successfully finished installing Vulkan SDK in these environments, to test Vulkan Memory Allocator project. Here is how to do it:
In AppVeyor I have everything configured on their website, so you can’t really see configuration file. To download Vulkan SDK, I used
curl --silent --show-error --output VulkanSDK.exe https://vulkan.lunarg.com/sdk/download/126.96.36.199/windows/VulkanSDK-188.8.131.52-Installer.exe
First command downloads and second one installs Vulkan SDK in silent mode. The SDK is installed to C:\VulkanSDK\184.108.40.206 directory.
Next I added an environmental variable in Environment > Environmental variables section:
In my Visual Studio project settings, I added include directory "$(VULKAN_SDK)/Include" and library directory "$(VULKAN_SDK)/Lib". Then I could successfully
#include <vulkan/vulkan.h> and link with vulkan-1.lib.
For Travis CI you can see my current configuration file as: .travis.yml. What I did here is I added few commands to
install section. First there are some
apt-get commands that install some additional libraries, which I took from Getting Started with the Vulkan SDK page:
sudo apt-get -qq update
sudo apt-get install -y libassimp-dev libglm-dev graphviz libxcb-dri3-0 libxcb-present0 libpciaccess0 cmake libpng-dev libxcb-dri3-dev libx11-dev libx11-xcb-dev libmirclient-dev libwayland-dev libxrandr-dev
Then I download and install Vulkan SDK. URL to real file is in the same format as for Windows. I used
wget command for downloading. The file is a self-extracting archive that unpacks SDK content to following subdirectory of current directory: VulkanSDK/220.127.116.11/x86_64.
wget -O vulkansdk-linux-x86_64-18.104.22.168.run https://vulkan.lunarg.com/sdk/download/22.214.171.124/linux/vulkansdk-linux-x86_64-126.96.36.199.run
chmod ugo+x vulkansdk-linux-x86_64-188.8.131.52.run
Finally I issue a command that sets environmental variable pointing to the SDK, to have it available in the code just like on Windows:
Then I needed to configure my project to search for include files in "$(VULKAN_SDK)/include" and library files in "$(VULKAN_SDK)/lib" (directory names are lowercase this time!). Finally I could
#include <vulkan/vulkan.h> and link with libvulkan.so.
