If you're looking for Lantern binaries, you can find all of them at the following links:
If you're looking for help, please visit below user forums:
We are going to create a Docker image that will take care of compiling Lantern for Windows and Linux, in order to compile Lantern for OSX you'll need an OSX host, this is a limitation caused by Lantern depending on C code and OSX build tools for certain features.
Building the docker image
In order to build the docker image open a terminal,
cd into the
lantern project and execute
cd lantern make docker
This will take a while, be patient, you only need to do this once.
Building Lantern binaries
Building for Linux
If you want to build for Linux on all supported architectures, use:
You can also build for Linux 386:
make linux-386 file lantern_linux_386 # lantern_linux_386: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), not stripped
Or only for amd64:
make linux-amd64 file lantern_linux_amd64 # lantern_linux_amd64: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), not stripped
make linux-arm file lantern_linux_arm # lantern_linux_arm: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), not stripped
Building for Windows
Lantern supports the 386 architecture on Windows. In order to build Lantern on Windows use:
make windows file lantern_windows_386.exe # lantern_windows_386.exe: PE32 executable for MS Windows (GUI) Intel 80386 32-bit
Building for OSX
Lantern supports the amd64 architecture on OSX. In order to build Lantern on OSX you'll need an OSX host. Run the following command:
make darwin file lantern_darwin_amd64 # lantern_darwin_amd64: Mach-O 64-bit executable x86_64
Building all binaries
If you want to build all supported binaries of Lantern use the
Building headless version
HEADLESS environment variable is set, the generated binaries will be
headless, that is, it doesn't depend on the systray support libraries, and
will not show systray or UI.
Packaging requires some special environment variables.
Lantern on OS X is packaged as the
Lantern.app app bundle, distributed inside
of a drag-and-drop dmg installer. The app bundle and dmg can be created using:
VERSION=2.0.0-beta2 make package-darwin file Lantern.dmg # Lantern.dmg: bzip2 compressed data, block size = 100k
make package-darwin signs the Lantern.app using the BNS code signing
certificate in your KeyChain. The
can be obtained from
too-many-secrets and must be
installed to the system's key chain beforehand.
If signing fails, the script will still build the app bundle and dmg, but the app bundle won't be signed. Unsigned app bundles can be used for testing but should never be distributed to end users.
The background image for the DMG is
Packaging for Windows
Lantern on Windows is distributed as an installer built with
nsis. The installer is built and signed with
make package-windows to be able to sign the executable, the environment varaibles
BNS_CERT_PASS must be set to point to the secrets directory
of the BNS certificate. You can set the environment variables and run the
script on one line, like this:
SECRETS_DIR=$PATH_TO_TOO_MANY_SECRETS BNS_CERT_PASS='***' \ VERSION=2.0.0-beta1 make package-windows
Packaging for Ubuntu
Lantern on Ubuntu is distributed as a
.deb package. You can generate a Debian
VERSION=2.0.0-beta2 make package-linux
The version string must match the Debian requirements:
This will build both 386 and amd64 packages.
Generating all packages
make packages task combining all the arguments that
SECRETS_DIR=$PATH_TO_TOO_MANY_SECRETS BNS_CERT_PASS='***' \ VERSION=2.0.0-beta1 make packages
Releasing for QA
Then, create all distribution packages:
[...env variables...] make packages
release-qa to upload the packages that were just generated to
both AWS S3 and the Github release page:
VERSION=2.0.0-beta5 make release-qa
If you want to release a beta you must have created a package for QA first,
then use the
release-beta will promote the QA files that are currently in S3 to beta.
Releasing for production
After you're satisfied with a beta version, it will be time to promote beta packages to production and to publish the packages for auto-updates:
VERSION=2.0.0-beta5 GH_TOKEN=$GITHUB_TOKEN make release
make release expects a
lantern-binaries directory at
You can provide a different directory by passing the
Creating the Android embeddable library
In order to build the Android ARM library that can be embedded in applications,
Lantern is using
gomobile. This simplifies the process notably.
Currently, as Go 1.5 is not stable, a specific git revision is used within an isolated Docker image.
To build a development library (takes shorter time):
To build the final version for Firetweet:
If you pass the
FIRETWEET_MAIN_DIR env variable to
make android-lib, the
generated bindings and library will be copied into it:
FIRETWEET_MAIN_DIR=/path/to/firetweet/src/main make android-lib
You can also override this environment variable if you want to use the Flashlight Android Tester app.
If the environment variable
UPDATE_DIST=true is set,
make genassets also
updates the resources in the dist folder.
An annotated tag can be added like this:
git tag -a v1.0.0 -m"Tagged 1.0.0" git push --tags
make create-tag as a shortcut for creating and uploading tags:
VERSION='2.0.0-beta5' make create-tag
If you want to both create a package and upload a tag, run the
right after the
[...env variables...] make packages create-tag
The icons used for the system tray are stored in
src/github/getlantern/lantern/icons. To apply changes to the icons, make
your updates in the icons folder and then run
Continuous Integration with Travis CI
Continuous builds are run on Travis CI. These builds use the
configuration. The github.com/getlantern/cf unit tests require an envvars.bash
to be populated with credentials for cloudflare. The original
An encrypted version is checked in as
envvars.bash.enc, which was encrypted
per the instructions here.
Documentation for developers
Please, go to README-dev for an in-depth explanation of the Lantern internals and cloud services.
Lantern is a gost project that provides repeatable builds and consolidated pull requests for lantern.
Go code in Lantern must pass several tests:
You can find a generic git-hook
file, which can be used as a pre-push (or pre-commit) hook to automatically
ensure these tests are passed before committing any code. Only Go packages in
src/github.com/getlantern will be tested, and only those that have changes in
Install by copying it into the local
.git/hooks/ directory, with the
file name if you want to run it before pushing. Alternatively, you can name it
pre-commit to run it before each commit..
If you must commit without running the hooks, you can run git with the
