Prerequisites
To compile CanvasKit, you will first need to install emscripten. This
will set the environment EMSDK (among others) which is required for
compilation.
Compile and Test Locally
make release # make debug is much faster and has better error messages
make local-example
This will print a local endpoint for viewing the example. You can experiment
with the CanvasKit API by modifying ./canvaskit/example.html and refreshing
the page. For some more experimental APIs, there's also ./canvaskit/extra.html.
For other available build targets, see Makefile and compile.sh.
For example, building a stripped-down version of CanvasKit with no text support or
any of the "extras", one might run:
./compile.sh no_skottie no_particles no_font
Such a stripped-down version is about half the size of the default release build.
Infrastructure Playbook
When dealing with CanvasKit (or PathKit) on our bots, we use Docker. Check out $SKIA_ROOT/infra/wasm-common/docker/README.md for more on building/editing the images used for building and testing.
Updating the version of Emscripten we build/test with
This presumes you have updated emscripten locally to a newer version of the sdk and verified/fixed any build issues that have arisen.
- Edit
$SKIA_ROOT/infra/wasm-common/docker/emsdk-base/Dockerfileto install and activate the desired version of Emscripten. - Edit
$SKIA_ROOT/infra/wasm-common/docker/Makefileto haveEMSDK_VERSIONbe set to that desired version. If there is a suffix that is not_v1, reset it to be_v1. If testing the image later does not work and edits are made to the emsdk-base Dockerfile to correct that, increment to_v2,_v3, etc to force the bots to pick up the new image. - In
$SKIA_ROOT/infra/wasm-common/docker/, runmake publish_emsdk_base - Edit
$SKIA_ROOT/infra/canvaskit/docker/canvaskit-emsdk/Dockerfileto be based off the new version from step 2. CanvasKit has its own docker image because it needs a few extra dependencies to build with font support. - Edit
$SKIA_ROOT/infra/canvaskit/docker/Makefileto have the same version from step 2. It's easiest to keep theemsdk-baseandcanvaskit-emsdkversions be in lock-step. - In
$SKIA_ROOT/infra/canvaskit/docker/, makepublish_canvaskit_emsdk. - In
$SKIA_ROOT/infra/bots/recipe_modules/build/, updatecanvaskit.pyandpathkit.pyto haveDOCKER_IMAAGEpoint to the desired tagged Docker containers from steps 2 and 5 (which should be the same). - In
$SKIA_ROOT/infra/bots/, runmake trainto re-train the recipes. - Optional: Run something like
git grep 1\\.38\\.in$SKIA_ROOTto see if there are any other references that need updating. - Upload a CL with all the changes. Run all Test.+CanvasKit, Perf.+CanvasKit, Test.+PathKit, Perf.+PathKit jobs to make sure the new builds pass all tests and don't crash the perf harnesses.
- Send out CL for review. Feel free to point the reviewer at these steps.
