# Building SKQP for Fuchsia Using an arm64 device as an example, to build skqp for Fuchsia: ``` gn gen out/fuchsia-arm64 --args="is_official_build=false is_debug=false skia_update_fuchsia_sdk=true target_cpu=\"arm64\" target_os=\"fuchsia\" using_fuchsia_sdk=true skia_tools_require_resources=true skia_skqp_global_error_tolerance=8" ``` The effect of `skia_update_fuchsia_sdk=true` is that it will download both the Fuchsia SDK and a compatible clang for building SKQP as part of the `gn gen ...` step above. Next step, compile skqp for Fuchsia: ``` autoninja -C out/fuchsia-arm64 ":skqp_repo" ``` The effect of this build will be to produce a Fuchsia package repository named `skqp_repo` in the `out` directory of the build. `skqp_repo` can then be served to a Fuchsia device using `//fuchsia/sdk/tools/pm serve -repo skqp_repo` (where // is the skia build root). See [install fuchsia packages](https://fuchsia.dev/fuchsia-src/development/sdk/documentation/packages#install-package) for more on serving packages to Fuchsia devices. # Fuchsia CIPD Package Creation and Upload Procedure These steps assume the creation of the arm64 CIPD package as an example. Because the package requires a path from the output directory of the build, the `gn gen` arguments must match the prescribed path declared in `cipd_arm64.yaml` in order for this CIPD package creation and upload to succeed. ## Create CIPD Package ``` cipd create -pkg-def=cipd_arm64.yaml ``` ## Set CIPD Ref of `latest` If applicable, set `latest` ref to new CIPD package. ``` cipd set-ref skia/fuchsia/skqp/arch/arm64 -ref latest -version mdhS7sryb2zxQuXT803Dv_XZ0r7B5j8jSbZmIi0JvOcC ``` ## Set the git-commit Tag ``` cipd set-tag skia/fuchsia/skqp/arch/arm64 -tag=git-commit:9c2b7cfe9080c6c4692234667a671db216a2e229 -version mdhS7sryb2zxQuXT803Dv_XZ0r7B5j8jSbZmIi0JvOcC ```
