Fuchsia samples using the Fuchsia SDK

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

Set up and bootstrap the SDK samples repository

Clone this SDK samples repository on your host machine. This repository contains the Bazel-based Fuchsia SDK and sample components.

The tasks include:

  • Bootstrap the SDK samples repository.
  • Download the SDK toolchain to initialize the SDK environment.
  • Verify that you can run ffx commands.

Do the following:

  1. Open a terminal.

  2. In the terminal, change to your home directory:

    cd

  3. Clone the Fuchsia samples repository:

    git clone https://fuchsia.googlesource.com/sdk-samples/getting-started fuchsia-getting-started --recurse-submodules

    This git clone command creates a new directory named fuchsia-getting-started and clones the content of the SDK samples repository{:.external}.

  4. Go to the new directory:

    cd fuchsia-getting-started

  5. Run the bootstrap script to install Bazel and other required dependencies:

    scripts/bootstrap.sh

  6. To verify that you can use the ffx tool in your environment, run the following command:

    tools/ffx sdk version

    This command prints output similar to the following:

    $ tools/ffx sdk version
21.20240623.2.1

    At this point, you only need to confirm that you can run ffx commands without error.

    Note: The output above shows the version 21.20240623.2.1, which indicates that this SDK was built and published on June 23, 2024.

Building and flashing the reference product to vim3

Once you have downloaded the toolchain, you will be able to build products. Here, you will need a vim3 plugged into your computer to build and flash a product bundle to it. Remote desktops may not allow for flashing to vim3.

  1. Make sure the device is in fastboot:

    tools/ffx target reboot -b

  2. Check for the target:

    tools/ffx target list

    This should print an output similar to the following

    NAME                      SERIAL          TYPE       STATE      ADDRS/IP                            RCS
fuchsia-c863-1474-66db    c863147466db    Unknown    Fastboot    [fe80::37a4:2a98:628b:3687%eth0,    Y
                                                              172.16.243.55]

  3. Flash and build the reference product:

    tools/bazel run products/reference:reference.vim3.flash

    This should print an output similar to the following:

Now you have successfully flashed the reference product to a vim3. You can use the command below to ssh into the target:

tools/ffx target ssh

Use the command below to find more commands you can use with your flashed target:

tools/ffx target help

Booting up a Fuchsia emulator

Something else you can do is boot the product in an emulator

  1. Build and start the emulator

    tools/bazel run products/reference:reference.x64.emu

    Optionally, if you want to ssh into the emulator instead of using the terminal window, use the following command.

    tools/ffx target ssh

Running a session on the emulator

A session is a component. Each Fuchsia product builds its user experience within a session

  1. Once your emulator is running, you can see that a terminal window pops up on the screen that shows a fuchsia colored square in the middle. This is part of the session that automatically runs when you run the product. Run the following command to see the logs of your session.

    tools/ffx log --filter reference_session

    This should print an output similar to the following:

    [01546.453857][session:session] INFO: Welcome to Fuchsia!
[01546.453896][session:session] INFO: Develop on Fuchsia!

    Optionally, to stop the session, run the following command

    tools/ffx session stop

    You will see that the terminal window no longer has the colored square.

Now, feel free to add your own message to this binary that the session's component runs and change the color of the square in these following files, respectively.

src/reference_session:main.cc

src/reference_session:graphical_window.cc

Close the terminal window and rerun the emulator to test your changes.
