### Initializing a New Project with Git Submodule (Shell)

Source: https://github.com/frida/releng/blob/main/README.md

This snippet demonstrates the initial setup steps for a new project, including initializing a Git repository, adding the `releng` submodule, copying essential Meson build scripts, and configuring `.gitignore` to exclude build and dependency directories.

```sh
$ git init my-project
$ cd my-project
$ git submodule add https://github.com/frida/releng.git
$ cp releng/meson-scripts/* .
$ echo -e '/build/\n/deps/' > .gitignore
```

### Defining a Simple Vala Application (Vala)

Source: https://github.com/frida/releng/blob/main/README.md

This snippet provides a basic 'hello.vala' source file. It defines a `main` function that prints 'Hello World from Vala!' to the console and returns 0, serving as a minimal example for the project.

```vala
int main (string[] args) {
	print ("Hello World from Vala!\n");
	return 0;
}
```

### Cross-Compiling for Raspberry Pi (Shell)

Source: https://github.com/frida/releng/blob/main/README.md

This snippet details the steps for cross-compiling the project for Raspberry Pi. It includes installing the `g++-arm-linux-gnueabihf` cross-compiler, then configuring with `--host=arm-linux-gnueabihf` and building with `make`.

```sh
$ sudo apt-get install g++-arm-linux-gnueabihf
$ ./configure --host=arm-linux-gnueabihf
$ make
```

--------------------------------

### Building and Running the Project (Shell)

Source: https://github.com/frida/releng/blob/main/README.md

This snippet illustrates how to build the project using `make` and then execute the compiled 'hello' application located in the 'build' directory, demonstrating the successful compilation and output.

```sh
$ make
$ ./build/hello
Hello World from Vala!
```

--------------------------------

### Configuring Meson Build File (Meson)

Source: https://github.com/frida/releng/blob/main/README.md

This snippet shows the basic `meson.build` configuration for a new project. It defines the project name, language (Vala), version, and an executable target named 'hello' from 'hello.vala', linking against the 'glib-2.0' dependency.

```meson
project('my-project', 'vala', version: '1.0.0')
executable('hello', 'hello.vala', dependencies: dependency('glib-2.0'))
```

### Cross-Compiling for iOS (Shell)

Source: https://github.com/frida/releng/blob/main/README.md

This snippet shows the commands to configure and build the project for iOS ARM64 architecture. It uses the `./configure` script with the `--host=ios-arm64` flag, followed by `make` to compile.

```sh
$ ./configure --host=ios-arm64
$ make
```

### Cross-Compiling for Android (Shell)

Source: https://github.com/frida/releng/blob/main/README.md

This snippet provides the commands to configure and build the project for Android ARM64 architecture. It uses the `./configure` script with the `--host=android-arm64` flag, followed by `make` to compile.

```sh
$ ./configure --host=android-arm64
$ make
```
