SDK Samples: Fortune Teller

This repository contains instructions and source code to build, package and run Fuchsia samples using only the Fuchsia SDK.

Requirements

1. Install a Bazel version no older than the one defined in the WORKSPACE.bazel file, by following the instructions at https://bazel.build/install. In some Linux distributions, sudo apt-get install bazel should be enough.

2. Make sure this repository has the required submodules:

   git submodule update --recursive --init
   

3. Ensure that there are Fuchsia SSH keys in your host machine. You will need them for running the Fuchsia emulator.

    [[ -f "${HOME}/.ssh/fuchsia_ed25519" ]] || ssh-keygen -P "" -t ed25519 -f "${HOME}/.ssh/fuchsia_ed25519" -C "${USER}@$(hostname -f) Shared SSH Key for Fuchsia"
   
    [[ -f "${HOME}/.ssh/fuchsia_authorized_keys" ]] || ssh-keygen -y -f "${HOME}/.ssh/fuchsia_ed25519" > "${HOME}/.ssh/fuchsia_authorized_keys"
   

Build and package the sample

Now the repository is ready to build the sample.

1. Fetch an emulator image and start an emulator

   tools/ffx product-bundle get workstation.qemu-x64
   tools/ffx emu start -H workstation.qemu-x64
   

2. (optional) watch the device log in a separate window

   tools/ffx log
   

3. Run the fortune-teller component

   bazel run --config=fuchsia_x64 //src/fortune_teller:pkg.component
   

   Watch that your fortune is printed in the log.
