mafredri / build_chromium_headless.sh
Created March 9, 2017 16:09
Script to build (and update) headless Chromium on Ubuntu
#!/usr/bin/env zsh
# This script checks out the latest chromium and builds the headless
# version of it. When the chromium source is already present, the
# repository is updated.
#
# A .tar.gz is created in $DIR containing the headless_shell binary,
# this binary runs chromium. The resulting binary should be quite
# portable given that the (few) dependencies are installed on the target
# machine.
