## Introduction
2023-09-12 08:43:09 -05:00
2023-08-01 21:37:38 -05:00
This guide covers setting up environments for core, Flutter/Dart, and Python development. See the relevent sections.
## Obtaining the source code
```shell
2023-09-02 20:13:08 -05:00
git clone https://gitlab.com/veilid/veilid.git
2023-08-01 21:37:38 -05:00
```
## Dependencies
### GNU/Linux
Development of Veilid on GNU/Linux requires a Debian variant such as Debian
itself, Ubuntu or Mint. Pull requests to support other distributions would be
welcome!
Running the setup script requires:
2023-09-12 08:43:09 -05:00
2023-08-01 21:37:38 -05:00
* Android SDK and NDK
* Rust
2023-09-12 08:43:09 -05:00
You may decide to use Android Studio [here ](https://developer.android.com/studio )
to maintain your Android dependencies. If so, use the dependency manager
2023-08-01 21:37:38 -05:00
within your IDE. If you plan on using Flutter for Veilid development, the Android Studio
2023-09-12 08:43:09 -05:00
method is highly recommended as you may run into path problems with the 'flutter'
command line without it. If you do so, you may skip to
2023-08-01 21:37:38 -05:00
[Run Veilid setup script ](#Run Veilid setup script ).
* build-tools;33.0.1
* ndk;25.1.8937393
* cmake;3.22.1
* platform-tools
* platforms;android-33
#### Setup Dependencies using the CLI
You can automatically install the prerequisites using this script:
```shell
2023-08-18 08:19:07 -05:00
./dev-setup/install_linux_prerequisites.sh
2023-08-01 21:37:38 -05:00
```
Otherwise, you may choose to use Android `sdkmanager` . Follow the installation
instructions for `sdkmanager`
[here ](https://developer.android.com/studio/command-line/sdkmanager ), then use
the command line to install the requisite package versions:
```shell
sdkmanager --install "platform-tools"
sdkmanager --install "platforms;android-33"
sdkmanager --install "build-tools;33.0.1"
sdkmanager --install "ndk;25.1.8937393"
sdkmanager --install "cmake;3.22.1"
```
Export environment variables and add the Android SDK platform-tools directory to
your path.
```shell
cat < < EOF > > ~/.profile
export ANDROID_SDK_ROOT=< path to sdk >
export ANDROID_NDK_HOME=$ANDROID_SDK_ROOT/ndk/25.1.8937393
export PATH=\$PATH:$ANDROID_SDK_ROOT/platform-tools
EOF
```
#### Run Veilid setup script
Now you may run the Linux setup script to check your development environment and
pull the remaining Rust dependencies:
```shell
2023-08-18 08:19:07 -05:00
./dev-setup/setup_linux.sh
2023-08-01 21:37:38 -05:00
```
#### Run the veilid-flutter setup script (optional)
If you are developing Flutter applications or the flutter-veilid portion, you should
install Android Studio, and run the flutter setup script:
```shell
cd veilid-flutter
./setup_flutter.sh
```
### macOS
Development of Veilid on MacOS is possible on both Intel and ARM hardware.
Development requires:
2023-09-12 08:43:09 -05:00
* Android Studio
2023-08-01 21:37:38 -05:00
* Xcode, preferably latest version
* Homebrew [here ](https://brew.sh )
* Android SDK and NDK
* Rust
2023-09-12 08:43:09 -05:00
You will need to use Android Studio [here ](https://developer.android.com/studio )
2023-08-01 21:37:38 -05:00
to maintain your Android dependencies. Use the SDK Manager in the IDE to install the following packages (use package details view to select version):
2023-09-12 08:43:09 -05:00
2023-08-01 21:37:38 -05:00
* Android SDK Build Tools (33.0.1)
* NDK (Side-by-side) (25.1.8937393)
* Cmake (3.22.1)
* Android SDK 33
* Android SDK Command Line Tools (latest) (7.0/latest)
#### Setup command line environment
Export environment variables and add the Android SDK platform-tools directory to
your path.
```shell
cat < < EOF > > ~/.zshenv
export ANDROID_SDK_ROOT=$HOME/Library/Android/sdk
export ANDROID_NDK_HOME=$HOME/Library/Android/sdk/ndk/25.1.8937393
export PATH=\$PATH:$HOME/Library/Android/sdk/platform-tools
EOF
```
2023-09-12 08:43:09 -05:00
#### Run Veilid setup script (macOS)
2023-08-01 21:37:38 -05:00
Now you may run the MacOS setup script to check your development environment and
pull the remaining Rust dependencies:
```shell
2023-08-18 08:19:07 -05:00
./dev-setup/setup_macos.sh
2023-08-01 21:37:38 -05:00
```
2023-09-12 08:43:09 -05:00
#### Run the veilid-flutter setup script (optional) (macOS)
2023-08-01 21:37:38 -05:00
If you are developing Flutter applications or the flutter-veilid portion, you should
install Android Studio, and run the flutter setup script:
```shell
cd veilid-flutter
./setup_flutter.sh
```
### Windows
2023-09-03 02:44:25 -05:00
For a simple installation allowing Rust development, follow these steps:
2023-09-12 08:43:09 -05:00
Install Git from < https: / / git-scm . com / download / win >
2023-09-03 02:44:25 -05:00
2023-09-15 13:24:25 -05:00
Install Rust from < https: / / static . rust-lang . org / rustup / dist / x86_64-pc-windows-msvc / rustup-init . exe > (this may prompt you to run the Visual Studio Installer, and reboot, before proceeding).
2023-09-03 02:44:25 -05:00
2023-09-15 13:24:25 -05:00
Ensure that protoc.exe is in a directory in your path. For example, it can be obtained from < https: / / github . com / protocolbuffers / protobuf / releases / download / v24 . 3 / protoc-24 . 3-win64 . zip >
2023-09-03 02:44:25 -05:00
2023-09-15 13:24:25 -05:00
Ensure that capnp.exe (for Cap’ n Proto 1.0.1) is in a directory in your path. For example, it can be obtained from the < https: / / capnproto . org / capnproto-c + + -win32-1 . 0 . 1 . zip > distribution. Please note that the Windows Package Manager Community Repository (i.e., winget) as of 2023-09-15 has version 0.10.4, which is not sufficient.
2023-09-03 02:44:25 -05:00
Start a Command Prompt window.
```shell
git clone https://gitlab.com/veilid/veilid.git
cd veilid
cargo build
cd target
cd debug
veilid-server.exe
```
This may result in a popup window from local security software, asking whether you wish to allow network access by veilid-server.exe.
To use the CLI, navigate to the above `debug` directory in another Command Prompt window (while veilid-server.exe is still running), and type:
```shell
veilid-cli.exe
```
2023-08-01 21:37:38 -05:00
## Running the Application(s)
### Veilid Server
In order to run the `veilid-server` locally:
```shell
cd ./veilid-server
cargo run
```
In order to see what options are available:
```shell
cargo run -- --help
```
#### Configuration
`veilid-server` has a wealth of configuration options. Further documentation on
the format of the `veilid-server.conf` file may be found [in the project /doc
directory](./doc/config/veilid-server-config.md).
When running `veilid-server` in a Unix-like environment, the application will
look for its config file under `/etc/veilid-server/` . If the config file is not
found in this location, `veilid-server` will follow the XDG user directory spec
and look in `~/.config/veilid-server` .
When running under Windows, the `veilid-server.conf` file may be created at
`C:\Users\<user>\AppData\Roaming\Veilid\Veilid\` , and when running under macOS,
at `/Users/<user>/Library/Application Support/org.Veilid.Veilid` .
### Veilid CLI
In order to connect to your local `veilid-server` :
```shell
cd ./veilid-cli
cargo run
```
Similar to `veilid-server` , you may see CLI options by typing:
```shell
cargo run -- --help
```
## Building the Application
### Linux Packages
Veilid server and cli can be built locally using the
[Earthly ](https://earthly.dev/ ) framework. After [installing earthly on your
local machine](https://earthly.dev/get-earthly), you may use the `earthly` cli
to initiate a build:
```shell
earthly +package-linux
```
This will assemble all dependencies and build `.deb` packages for both amd64 and
arm64 platforms. Earthly, built on Docker, caches build layers, so after a
longer first build, subsequent builds should be much quicker.
During development, you may want to kick off specific build steps. To see a list
of the build steps configured, consult the `Earthfile` , or you may use the
`earthly` cli:
```shell
earthly ls
```
