Visual Studio
To build the Vulkan ICD library, use Visual Studio 2019 to open the project folder and wait for it to run CMake. Open the CMake Targets View in the Solution Explorer and select the vk_swiftshader project to build it.
On Windows, most applications can be made to use SwiftShader's DLLs by placing them in the same folder as the executable. On Linux, the LD_LIBRARY_PATH environment variable or -rpath linker option can be used to direct applications to search for shared libraries in the indicated directory first.
All changes require a Change-ID tag in the commit message. A commit hook may be used to add this tag automatically, and can be found at: -review.googlesource.com/tools/hooks/commit-msg. You can execute git clone and manually place the commit hook in SwiftShader/.git/hooks/, or to clone the repository and install the commit hook in one go:
Some tests will automatically be run against the change. Notably, presubmit.sh verifies the change has been formatted using clang-format 11.0.1. Most IDEs come with clang-format support, but may require upgrading/downgrading to the clang-format version 11.0.0 release version (notably Chromium's buildtools has a clang-format binary which can be an in-between revision which produces different formatting results).
googletest contains the Google Test project, as a Git submodule. It is used for running unit tests for Chromium, and Reactor unit tests. Run git submodule update --init to obtain/update the code. Any contributions should be made upstream.

I'm trying to export an image rendered with WebGL on a linux server without a GPU. To do this I'm using headless Chrome however the exported image is black (example exported image, taking a screenshot of page shows its just canvas that is black). I was hoping for some help figuring out why this is happening.
To export the image I render the image into a canvas, export data via canvas.toDataURL('image/jpeg') and then post the data to the server. I'm using Pixi.js for rendering, if I use canvas renderer then everything works on the server; It's WebGL rendering thats not working. It's worth noting the WebGL render works fine in Chrome 63 on a Macbook.
The swiftshader author said in June headless WebGL rendering is possible and it seems to be confirmed by this Chromium issue so I guess I'm missing something. Has anyone got any ideas what I'm doing wrong?
There's an open bug which affects systems without X11 libraries: crbug.com/swiftshader/79. It prevents Chrome OS from running with SwiftShader, but the same issue would also happen on a headless Linux system which has no X11 support.
Fortunately it should be feasible to install X11 and get things running. I'm not 100% sure which packages provide the necessary libraries, but try these: xorg xserver-xorg xvfb libx11-dev libxext-dev libxext-dev:i386
WebGL 1.0 is based on OpenGL ES 2.0 spec, which is based on OpenGL 2.1 spec. There is Mesa library( _(computer_graphics)), which implements software renderer and is used for validation of OpenGL implementation by vendors. I think it supports OpenGL up to 3.1, but I can be wrong and now it supports version even highier.
