**Building IPATool from source requires Go 1.22 or later, cloning the majd/ipatool repository, and running `go build -o ipatool ./main` to produce the executable binary.**

IPATool is an open-source command-line utility written in Go that enables interaction with Apple's App Store APIs for searching, purchasing, and downloading IPA files. Because it is distributed as source code via GitHub, you can build IPATool from source to compile a native binary for your specific operating system and architecture. This guide walks through the complete build process using the actual source structure found in the `majd/ipatool` repository.

## Prerequisites

Before you begin, ensure your system meets the following requirements:

- **Go 1.22 or later**: IPATool uses modern Go modules and language features. Verify your installation with `go version`.
- **Git**: Required to clone the repository.

```bash
go version

```

## Clone the Repository

First, download the source code from GitHub. The repository uses standard Go project layout with the main entry point located at [`main/main.go`](https://github.com/majd/ipatool/blob/main/main/main.go).

```bash
git clone https://github.com/majd/ipatool.git
cd ipatool

```

## Understanding the Project Structure

Familiarity with the codebase layout helps when troubleshooting build issues or contributing modifications:

- **`go.mod`**: Defines module dependencies including `github.com/spf13/cobra` for CLI commands and keychain libraries.
- **[`main/main.go`](https://github.com/majd/ipatool/blob/main/main/main.go)**: The application entry point that initializes the command tree and calls `cmd.Execute()`.
- **`cmd/`**: Contains individual subcommand implementations (search, download, login).
- **`pkg/appstore/`**: Core business logic for App Store API interactions.
- **`pkg/keychain/`**: Platform-specific credential storage implementations.

## Build Instructions

### Basic Build for Current Platform

Compile a binary for your local operating system and architecture:

```bash
go build -o ipatool ./main

```

This command reads [`main/main.go`](https://github.com/majd/ipatool/blob/main/main/main.go), resolves dependencies listed in `go.mod`, and produces an executable named `ipatool` (or `ipatool.exe` on Windows) in the current directory.

### Cross-Compilation

Go supports cross-compilation for multiple platforms without requiring platform-specific toolchains. Set the `GOOS` and `GOARCH` environment variables to target different systems:

```bash

# Build for macOS (Intel)

GOOS=darwin GOARCH=amd64 go build -o ipatool-darwin-amd64 ./main

# Build for macOS (Apple Silicon)

GOOS=darwin GOARCH=arm64 go build -o ipatool-darwin-arm64 ./main

# Build for Linux

GOOS=linux GOARCH=amd64 go build -o ipatool-linux-amd64 ./main

# Build for Windows

GOOS=windows GOARCH=amd64 go build -o ipatool-windows-amd64.exe ./main

```

### Install to System PATH

To install the binary permanently into your `$GOPATH/bin` directory (usually `$HOME/go/bin`):

```bash
go install ./...

```

Ensure `$GOPATH/bin` is added to your system PATH to invoke `ipatool` from any location.

## Key Source Files and Build Configuration

Several files control the build process and runtime behavior:

- **`go.mod`** (repository root): Declares the module path `github.com/majd/ipatool` and external dependencies.
- **`go.sum`** (repository root): Cryptographic checksums for dependency verification to ensure reproducible builds.
- **[`main/main.go`](https://github.com/majd/ipatool/blob/main/main/main.go)**: Entry point that imports `github.com/majd/ipatool/cmd` and calls the root command executor.
- **[`cmd/root.go`](https://github.com/majd/ipatool/blob/main/cmd/root.go)**: Defines root command flags and binds subcommands like `search`, `download`, and `login`.

The build process automatically embeds version information and compiles all packages under `pkg/`, including `pkg/appstore/` for API logic and `pkg/http/` for HTTP client configuration with caching support.

## Verification and Testing

After building, verify the binary works correctly:

```bash
./ipatool --help

```

Successful execution confirms that **Go modules** were resolved correctly and the **keychain** integration compiled for your platform.

## Troubleshooting Common Build Issues

- **"go: module not found" errors**: Run `go mod tidy` to ensure `go.mod` and `go.sum` are synchronized with the source code.
- **Keychain compilation failures on Linux**: Install `libsecret-1-dev` or `gnome-keyring` development headers, as the `pkg/keychain/` package requires CGO bindings on Linux systems.
- **Version mismatches**: If you encounter syntax errors, verify you are using Go 1.22+ as specified in the module requirements.

## Summary

Building IPATool from source provides full control over the compilation process and ensures compatibility with your specific system architecture:

- Install **Go 1.22 or later** and **Git** as prerequisites.
- Clone the `majd/ipatool` repository from GitHub.
- Use `go build -o ipatool ./main` to compile for your current platform.
- Leverage `GOOS` and `GOARCH` environment variables for cross-compilation.
- Install permanently with `go install ./...` to add to your system PATH.
- Key source files include [`main/main.go`](https://github.com/majd/ipatool/blob/main/main/main.go) for the entry point and `go.mod` for dependency management.

## Frequently Asked Questions

### What version of Go is required to build IPATool?

IPATool requires **Go 1.22 or later**, as defined in the `go.mod` file's module directives. Older versions may fail to compile due to language feature requirements in the `pkg/appstore/` and `cmd/` packages.

### Can I build IPATool on Windows?

Yes. Use `GOOS=windows GOARCH=amd64 go build -o ipatool.exe ./main` to produce a Windows executable. Note that the **keychain** functionality in `pkg/keychain/` is limited on Windows compared to macOS, and credential storage falls back to alternative mechanisms.

### How do I update IPATool after building from source?

Navigate to your local repository and pull the latest changes, then rebuild:

```bash
cd ipatool
git pull origin main
go build -o ipatool ./main

```

Alternatively, run `go install github.com/majd/ipatool@latest` to fetch and build the latest tagged release directly without manual cloning.

### Where is the compiled binary located after running go build?

By default, `go build` places the binary in the current working directory with the name specified by the `-o` flag (e.g., `./ipatool`). If you use `go install ./...`, the binary is placed in `$GOPATH/bin` or `$GOBIN` if that environment variable is set.
