Build Chromium failed (ensure_bootstrap: command not found)

Question

I tried to get the chromiumos source code and would like to built the chromiumos.

export BOARD=coral
./setup_board --board=${BOARD} --force
./build_packages --board=${BOARD}

But after the commands finished, i got some ERROR message, and I also try to update depot_tools but seems limited by permission denied...How can I solve it? Thanks!

Answer 1

you need to make sure depot_tools is in your $PATH at all times, including before you enter the sdk with cros_sdk

once inside the sdk, depot_tools is mounted at /mnt/host/depot_tools/ which should also be in your $PATH
