## Setup

1. Add this repository as a submodule to your project:

```console

git submodule init

git submodule add https://github.com/lithdew/solana-zig.git sol

git submodule update --init --recursive

```

2. In build.zig:

```zig

const std = @import("std");

const sol = @import("sol/build.zig");

// Assume 'step' is a *std.build.LibExeObjStep, and 'sol/' is the directory in

// which this repository is located within your project.

const sol_pkgs = sol.Packages("sol/");

inline for (@typeInfo(sol_pkgs).Struct.decls) |field| {

    step.addPackage(@field(sol_pkgs, field.name));

}

```

## Example

1. Setup build.zig:

```zig

const std = @import("std");

const sol = @import("sol/build.zig");

const sol_pkgs = sol.Packages("sol/");

pub fn build(b: *std.build.Builder) !void {

    const program = b.addSharedLibrary("helloworld", "main.zig", .unversioned);

    inline for (@typeInfo(sol_pkgs).Struct.decls) |field| {

        program.addPackage(@field(sol_pkgs, field.name));

    }

    program.install();

    try sol.linkSolanaProgram(b, program);

    try sol.generateProgramKeypair(b, program);

}

```

2. Setup main.zig:

```zig

const sol = @import("sol");

export fn entrypoint(_: [*]u8) callconv(.C) u64 {

    sol.print("Hello world!", .{});

    return 0;

}

```

3. Build and deploy your program on Solana devnet:

```console

$ zig build

Program ID: FHGeakPPYgDWomQT6Embr4mVW5DSoygX6TaxQXdgwDYU

$ solana airdrop -ud 1

Requesting airdrop of 1 SOL

Signature: 52rgcLosCjRySoQq5MQLpoKg4JacCdidPNXPWbJhTE1LJR2uzFgp93Q7Dq1hQrcyc6nwrNrieoN54GpyNe8H4j3T

882.4039166 SOL

$ solana program deploy -ud zig-out/lib/libhelloworld.so

Program Id: FHGeakPPYgDWomQT6Embr4mVW5DSoygX6TaxQXdgwDYU

```
