    make options reference

    The make command is used inside the Gaia repo to create a Gaia profile that can be loaded onto your device or run in a B2G Desktop build. This article looks in detail at the different make options available.

    Note: There are many environment variables present in the Makefile. Do not depend on them as they may be removed in the future.

    Created profiles are generally stored in the root of the gaia directory, for example /gaia/profile, and contain the following items:

    • defaults/: Directory containing default settings to be reloaded after you reset the phone.
    • extensions/: Directory containing extensions.
    • settings.json: Settings file.
    • user.js: Another file containing more settings/preferences.
    • webapps/: Directory containing all the web apps that are to be installed on the phone.

    Note: When you've already made a profile and you want to build a new one, you must delete the existing profile directory before trying to generate a new one.



    This simply gives you an unbranded, non-debug build. For a branded build you need to use Official Mozilla branding make; for a debug build you need Debug make.

    Push to device

    make install-gaia
    make reset-gaia

    With ADB (Android Debug Bridge) setup, these make targets will push Gaia to the device. install-gaia will just push updates of Gaia from your working directory to your device. reset-gaia will purge all existing configuration, profiles, web apps and database entries (a new settings database will be initialized) before pushing Gaia.

    Note: Pushing Gaia to your device using make install-gaia / make reset-gaia builds Gaia with 1x resolution assets by default. To specify higher resolution assets you need to use the GAIA_DEV_PIXELS_PER_PX or GAIA_DPPX make options (see High resolution image assets for more details of these options.). When pushing Gaia to your device in this fashion, you should specify the relevant make option along with your device's scale factor, so for example make install-gaia GAIA_DEV_PIXELS_PER_PX=1.5 for a Flame device (or 2, or 2.5, etc; see the scale factor values in the table inside 512 icon for device display.)

    Build specific apps

    APP=system make
    APP=system make install-gaia

    When a profile already exists, APP allows you to specify which app to re-package, instead of re-packing and re-pushing all the Gaia apps. Note that while this command pushes the new app package and the manifest, the manifest change (e.g. new permissions, keyboard layout declarations) will not get picked up by Gecko.

    Specify custom profile folder

    You can specify a custom directory to build your profile in, using PROFILE_FOLDER, for example:

    PROFILE_FOLDER=profile-b2g-desktop make

    Different device builds

    There are a few make options that create builds for different devices, with different purposes.

    Create a phone build of Gaia

    GAIA_DEVICE_TYPE=phone make

    This build gets apps from /gaia/build/config/phone/apps-engineering.list.

    Create a tablet build of Gaia

    GAIA_DEVICE_TYPE=tablet make

    This build gets apps from /gaia/build/config/tablet/apps-engineering.list.

    Different types of build

    There are a few make options that create different types of build, with different purposes.

    Production make

    PRODUCTION=1 make

    This creates a production build of Gaia:

    • Gaia is run as packaged apps, which are harder to debug, but are the best available state for apps in terms of available API permissions, etc.
    • Test apps are not included in the build
    • Remote debugging is turned off by default
    • Lock screen is turned on (which in turn will cut USB connections)
    • Marionette is turned off
    • First time user experience is turned on
    • Offline cache is used.

    Note: You can also use the alias make production.

    Debug make

    DEBUG=1 make

    The DEBUG variable runs Gaia as hosted apps on a built-in web server on a specific GAIA_PORT, rather than the default of packaged apps which have to be re-packaged after every change; this makes things easier to test. Launching the profile with the latest Firefox Nightly will also give you nice B2G specific panels on the Firefox Developer Tools.

    In addition:

    • Test apps are included in the build.
    • Remote debugging is turned on by default.
    • Lock screen is turned off (USB connections won't be interrupted.)
    • Marionette is turned on, which is needed when running Gaia unit tests.
    • First time user experience is turned off.
    • Offline cache is not used, even if it is generated.

    Device debug make

    DEVICE_DEBUG=1 make

    This disables screen lock on the device, and enables debugging with the ADB tool, so is useful for device debugging.

    In Firefox OS version > 1.2, specify this param when you want to debug Firefox OS webapps with the App Manager.

    Debug desktop make

    DEBUG=1 DESKTOP=0 make

    This option creates a desktop debug version, for running inside B2G desktop.

    Official Mozilla branding make


    Use this to make an official Mozilla-branded build.

    Dogfood make

    DOGFOOD=1 make

    Dogfooding options and utilities are turned on, for example the Feedback app, which allows dog fooders to easily submit feedback on the OS.

    System apps make

    B2G_SYSTEM_APPS=1 make

    This environment variable lets you push an app to /system/b2g instead of /data/local. You should use this when you work with a user build. This variable is automatically set when running make production. This can be used for install-gaia or reset-gaia too.

    Distribution and market customization build


    Note: Read Market Customizations for more details.

    Developer/debugging options

    There are also make options for adding/removing features or changing settings, for debugging purposes.

    Enable remote debugging


    This enables remote debugging on the device, the same as using the option in the developer settings.

    JavaScript optimization make

    GAIA_OPTIMIZE=1 make

    This triggers an optimization pass on Gaia's JavaScript, concatenating/compressing the files. This is automatically set when running make production. This can be used for install-gaia or reset-gaia too.

    High resolution image assets


    Or with alias:

    GAIA_DPPX=1.5 make

    When packaging the app, this option replaces images with their *@1.5x.(gif|jpg|png) equivalents if such images exist. You need to use the above option as part of a standard make command, for example:

    GAIA_DEV_PIXELS_PER_PX=1.5 make reset-gaia
    GAIA_DEV_PIXELS_PER_PX=1.5 make install-gaia

    Gaia is currently targetting the following screen resolutions:

    • qHD: ~540×960; device pixel ratio = 1.6875
    • WVGA: ~480×800; device pixel ratio = 1.5
    • HBGA (320x240); device pixel ratio = 1

    use GAIA_DEV_PIXELS_PER_PX to make sure the images looks sharp on qHD and WVGA devices. see A pixel is not a pixel for more information about device pixels per css pixels.

    Running integration tests

    You can run integration tests on Gaia using make. See Gaia integration tests for details.

    Running Raptor performance tests

    You need to configure your device for running Raptor tests prior to actually running the tests. See Raptor for details.

    make raptor

    Low memory profile build


    This variable generates a low memory profile version of Gaia, aimed at low memory devices like the Tarako.

    Disable first time use experience (FTU)


    Disable the FTU with this environment variable.

    Disable lockscreen

    You can disable the Firefox OS lockscreen using the NO_LOCK_SCREEN option, for example:

    NO_LOCK_SCREEN=1 make

    Reference Workloads

    Reference workloads allow developers/testers to quickly install a large amount of data in several applications, typically on a newly-flashed phone.

    The commands are (from the gaia directory):

    make reference-workload-light
    • 200 contacts
    • 200 sms messages
    • 50 dialer history entries
    • 20 gallery images
    • 20 songs
    • 5 videos
    make reference-workload-medium
    • 500 contacts
    • 500 sms messages
    • 100 dialer history entries
    • 50 gallery images
    • 50 songs
    • 10 videos
    make reference-workload-heavy
    • 1000 contacts
    • 1000 sms messages
    • 200 dialer history entries
    • 100 gallery images
    • 100 songs
    • 20 videos
    make reference-workload-x-heavy
    • 2000 contacts
    • 2000 sms messages
    • 500 dialer history entries
    • 250 gallery images
    • 250 songs
    • 50 videos

    These targets accept the APP environment variable, or an APPS environment variable that should contain the app names separated by a space, e.g.:

    APP=sms make reference-workload-light
    APPS="sms communications/contacts" make reference-workload-heavy

    The apps available are:

    APPS="gallery music video communications/contacts sms communications/dialer"

    In order to install music (songs) with reference workloads, the utility mid3v2 must be installed. This utility can be installed with:

    sudo apt-get install python-mutagen

    If you run Fedora or RHEL instead, use:

    sudo yum install python-mutagen

    Documentation make

    Gaia docs can be built, via jsdoc3. To generate these, you can use the following command:

    make docs

    Enabling IME layout and dictionaries

    To enable keyboard IME layout and dictionaries enabled, use following command structure:

    GAIA_KEYBOARD_LAYOUTS=en,zh-Hant-Zhuyin,el,de,fr,zh-Hans-Pinyin make

    We currently don't ship all the layouts by default due to disk space concerns. Bug 1029951 is being work on to decouple shipped layouts and it's dictionaries (by offering dictionary download to the users).

    Please look at the file build/config/keyboard-layouts.json to know all available layouts.
