The difference between 'managed' and 'should_process' is that the user specifies 'managed' via the -unmanaged command-line flag or a .gclient config, where 'should_process' is dynamically set by gclient if it goes over its recursion limit and controls gclient's behavior so it does not CMake (3.10.2 or later) (if desired) GN (if desired) Ninja (or other build tool) Python, for fetching dependencies [depot_tools] in your path; // dawn. googlesource. com / dawn dawn cd dawn Bootstrap the gclient configuration cp scripts / standalone. gclient . gclient Fetch external dependencies and toolchains with gclient gclient sync

Device or VM. Since Chrome OS uses a different toolchain for eachdevice model, you'll first need to know the name of the model (or "board") youwant to build for. For most boards, amd64-generic and arm-generic willproduce a functional binary, though it won't be optimized and may be missingfunctionality.Additional gclient setupEach board has its own toolchain and misc. build dependencies. To fetch these,list the board under the "cros_boards" gclient custom var. If you were usingthe amd64-generic board, your .gclient file would look like:solutions = [ { "url": " "name": "src", "custom_deps": {}, "custom_vars" : { "cros_boards": "amd64-generic", }, },]target_os = ["chromeos"]Once your .gclient file is updated, you will need to run gclient sync againto fetch the toolchain.NOTE:If you'd like a VM image additionally downloaded for the board, add it to the"cros_boards_with_qemu_images" gclient custom var. That var downloads theSDK along with a VM image. cros_boards downloads only the SDK.If you'd like to fetch multiple boards, add a : between each board in thegclient var. For example: "cros_boards": "amd64-generic:arm-generic".Building for the boardAfter the needed toolchain has been downloaded for your ${BOARD}, a build dirwill have been conveniently created for you at out_$BOARD/Release, which canthen be used to build Chrome. For the amd64-generic board, this wouldlook like:$ gn gen out_amd64-generic/Release$ autoninja -C out_$BOARD/Release chromeOr if you prefer to use your own build dir, simply add the following line to thetop of your GN args: import("//build/args/chromeos/amd64-generic.gni"). eg:$ gn gen out/Default --args='import("//build/args/chromeos/amd64-generic.gni")'$ autoninja -C out/Default chromeThat will produce a Chrome OS build of Chrome very similar

Chrome OS Build InstructionsChrome for Chromium OS can be built in a couple different ways. After followingthe initial setup, you'll need to choose one of the followingbuild configurations:If you're interested in testing Chrome OS code in Chrome, but not interactionswith Chrome OS services, you can build forlinux-chromeos using just a Linuxworkstation.Otherwise, Chrome's full integration can be covered by building for a realChrome OS device or VM using Simple Chrome.Use is_chromeos_device in GN and BUILDFLAG(IS_CHROMEOS_DEVICE) in C++ codeto differentiate between these two modes.[TOC]Common setupFirst, follow the normal Linux buildinstructionsas usual to get a Chromium checkout.You'll also need to add 'chromeos' to the target_os list in your .gclientconfiguration, which will fetch the additional build dependencies required forCrOS. This file is located one level up from your Chromium checkout's src.If you don't already have a target_os line present, simply add this to theend of the .gclient file:If you already have a target_os line present in your .gclient file, you cansimply append 'chromeos' to the existing list there. For example:target_os = ['android', 'chromeos']Once your .gclient file is updated, you will need to run gclient sync oncebefore proceeding with the rest of these instructions.Chromium OS on Linux (linux-chromeos)Chromium on Chromium OS uses Linux Chromium as a base, but adds a large numberof Chrome OS-specific features to the code. For example, the login UI, windowmanager and system UI are part of the Chromium code base and built into thechrome binary.Fortunately, most Chromium changes that affect Chromium OS can be built andtested on a Linux workstation.

Stable version is usually1-2wks behind the latest as Reclient needs to run a few days on testand staging environments without issues and degradations before it'sconsidered as stable.$CHECKOUT_DIR - the location where Reclient should be downloaded.Downloading binaries with gclientYou can configuregclientto download Reclient binaries during the gclient sync phase. Gclient expects aDEPS file in the repository’s root directory. The file contains components thatwill be checked out during the sync phase. To check out Reclient, the fileshould have a similar entry to:', ...}deps = { ...'': { 'packages': [ { 'package': 'infra/rbe/client/${{platform}}', 'version': Var('reclient_version'), } ], 'dep_type': 'cipd', },}">vars = { ... 'reclient_version': '', ...}deps = { ...'': { 'packages': [ { 'package': 'infra/rbe/client/${{platform}}', 'version': Var('reclient_version'), } ], 'dep_type': 'cipd', },}This will instruct gclient to check out of Reclient from/infra/rbe/client/ CIPD package into (example).Extracting a version to a variable (as in an example above) is optional, butprovides a benefit of being able to override the default value through gclient’scustom variables.Note: The snippet above will instruct gclient to download Reclient withGomaIP dependency processor. If you prefer Reclient with Clangscandeps, you'dneed to set package to infra/rbe/client/${{platform}}-csd.Using ReclientStarting and stopping reproxyReclient requires reproxy to be started at the beginning of the build, andstopped at the end. This is done through bootstrap binary by executingfollowing commands:Start:bootstrap -re_proxy=$reproxy_location [-cfg=$reproxy_config_location]Stop:bootstrap -re_proxy=$reproxy_location -shutdownConfigurationEach of Reclient’s binaries can be configured either by command line flags,environment variables, config files, or by combination of either of those (someflags provided in the command line while others in the config file or set asenvironment variables). If the same flag is defined in the command line and inthe config file or as an environment variable, the order of precedence isfollowing (from lowest to highest priority):Config fileEnvironment variableCommand line argumentTo use a configuration file, specify it with the -cfg=$config_file_locationflag. The config file is a list of flag_name=flag_value pairs, each on a newline. Example below:service=$RE_SERVER_ADDRESSinstance=$RE_SERVER_INSTANCEserver_address=unix:///tmp/reproxy.socklog_dir=/tmpoutput_dir=/tmpproxy_log_dir=/tmpdepsscanner_address=$scandeps_server_location #distributed with Reclientuse_gce_credentials=trueTo configure Reclient with environment variables, the variables should beprefixed with RBE_ (e.g. the value of RBE_service environment variable isused to set the service flag).RewrapperFull list of rewrapper config flags can be found indocs/cmd-line-flags.md. A few of the most commonlyused flags are:platform - Comma-separated key value pairs in the form key=value. Thisis used to identify remote platform settings like the docker image to use torun the command. The list of supported keys depends on RE Serverimplementation. A detailed lexicon can be foundhereserver_address - The address reproxy is running on. It needs to be setto the same value as reproxy’s server_address flag so that rewrapper andreproxy can communicate with each other. This value should be UDS onLinux/Mac (e.g. unix:///tmp/reproxy.sock) and a named pipe on Windows (e.g.pipe://reproxy.ipc). Depot_tools has a helper choosing the address based onthe platform(here).labels - Identifies the type of
