1 # Chromoting Build Instructions
3 Chromoting, also known as
4 [Chrome Remote Desktop](https://support.google.com/chrome/answer/1649523),
5 allows one to remotely control a distant machine, all from within the Chromium
6 browser. Its source code is located in the `remoting/` folder in the Chromium
7 codebase. For the sake of brevity, we'll assume that you already have a
8 pre-built copy of Chromium (or Chrome) installed on your development computer.
14 Before you can compile the code, you must obtain an API key to allow it to
15 access the federated Chromoting API.
17 1. Join the chromium-dev list, which can be found at
18 https://groups.google.com/a/chromium.org/forum/#!forum/chromium-dev. (This
19 step is required in order to gain access to the Chromoting API.)
20 1. Visit the Google APIs console at https://code.google.com/apis/console.
21 1. Use the `API Project` dropdown to create a new project with a name of
23 1. On the `Services` page, click the button to activate the
24 `Chrome Remote Desktop API`, and accept the license agreements that
26 1. On the `API Access` page, select the option to create an
27 `OAuth2 client ID`, and supply a product name of your choice.
28 1. Choose the `Web application` type, then click more options.
29 1. Replace the contents of `Authorized Redirect URLs` with:
30 `https://chromoting-oauth.talkgadget.google.com/talkgadget/oauth/chrome-remote-desktop/dev`
31 1. Clear the `Authorized JavaScript Origins` field and click the button to
32 finish creating the client ID.
33 1. Create a file `~/.gyp/include.gypi` according to the following format:
38 'google_api_key': '<API key, listed under Simple API Access in the console>',
39 'google_default_client_id': '<Client ID, listed under Client ID for web applications>',
40 'google_default_client_secret': '<Client secret, listed under Client ID for web applications>',
45 (NB: Replace the text in angled braces according the the instructions between
48 ## Obtain Chromium code
50 If you've already checked out a copy of the browser's codebase, you can skip
51 this section, although you'll still need to run `gclient runhooks` to ensure you
52 build using the API keys you just generated.
54 1. Install the build dependencies, which are listed at
55 http://code.google.com/p/chromium/wiki/LinuxBuildInstructionsPrerequisites.
56 1. Install the depot\_tools utilities, a process that is documented at
57 http://dev.chromium.org/developers/how-tos/install-depot-tools.
58 1. Download the Chromium source code by running:
59 `$ fetch chromium --nosvn=True`
61 ## Build and install the Linux host service
63 If you want to remote into a (Debian-based) GNU/Linux host, follow these steps
64 to compile and install the host service on that system. As of the time of
65 writing, you must compile from source because no official binary package is
68 1. Start in the `src/` directory that contains your checkout of the Chromium
70 1. Build the Chromoting host binaries:
73 $ ninja -C out/Release remoting_me2me_host remoting_start_host \
74 remoting_native_messaging_host remoting_native_messaging_manifests
77 1. When the build finishes, move into the installer directory:
78 `$ cd remoting/host/installer/`
79 1. Generate a DEB package for your system's package manager:
80 `$ linux/build-deb.sh`
81 1. Install the package on your system: `$ sudo dpkg -i *.deb`
82 1. The next time you use the Chromoting extension from your browser, it should
83 detect the presence of the host service and offer you the option to
84 `Enable remote connections`.
85 1. If the Web app doesn't properly detect the host process, you may need to
86 create a symlink to help the plugin find the native messaging host:
87 `$ sudo ln -s /etc/opt/chrome /etc/chromium`
89 (NB: If you compile the host service from source and expect to configure it
90 using the browser extension, you must also compile the latter from source.
91 Otherwise, the package signing keys will not match and the Web app's OAuth2
92 token will not be valid within the host process.)
94 ## Build and install the browser extension
96 The Web app is the Chromoting system's main user interface, and allows you to
97 connect to existing hosts as well as set up the host process on the machine
98 you're currently sitting at. Once built, it must be installed into your browser
101 1. Start in the `src/` directory that contains your checkout of the Chromium
103 1. Build the browser extension (Be sure to replace the substitutions denoted by
107 $ GOOGLE_API_KEY=<API key> GOOGLE_CLIENT_ID_REMOTING=<client ID> \
108 GOOGLE_CLIENT_SECRET_REMOTING=<client secret> \
109 ninja -C out/Release remoting_webapp
112 1. Install the extension into your Chromium (or Chrome) browser:
113 1. Visit the settings page [chrome://extensions].
114 1. If it is unchecked, tick the `Developer mode` box.
115 1. Click `Load unpacked extension...`, then navigate to
116 `out/Release/remoting/remoting.webapp/` within your code checkout.
117 1. Confirm the installation, open a new tab, and click the new app's
119 1. Complete the account authorization step, signing into your Google
120 account if you weren't already.
122 ## Build and install the Android client
124 If you want to use your Android device to connect to your Chromoting hosts,
125 follow these steps to install the client app on it. Note that this is in the
126 very early stages of development. At the time of writing, you must compile from
127 source because no official version is being distributed.
129 1. Follow all the instructions under the `Getting the code` and
130 `Install prerequisites` sections of: TODO: 404
131 http://code.google.com/p/chromium/wiki/AndroidBuildInstructions
132 1. Move into the `src/` directory that contains your checkout of the Chromium
134 1. Build the Android app: `$ ninja -C out/Release remoting_apk`
135 1. Connect your device and set up USB debugging:
136 1. Plug your device in via USB.
137 1. Open the Settings app and look for the `Developer options` choice.
138 1. If there is no such entry, open `About phone`, tap `Build number`
139 7 times, and look again.
140 1. Under `Developer options`, toggle the main switch to `ON` and enable
142 1. On your machine and still in the `src/` directory, run:
143 `$ build/android/adb_install_apk.py --apk=out/Release/apks/Chromoting.apk`
144 1. If your Android device prompts you to accept the host's key, do so.
145 1. The app should now be listed as Chromoting in your app drawer.
147 See the [chromoting_android_hacking.md] guide for instructions on viewing the
148 Android app's log and attaching a debugger.
