bun install
```

Build the Application

For Development (with hot reload)

bun run tauri dev

For Production Build

# Build the application
bun run tauri build

# The built executable will be in:
# - Linux: src-tauri/target/release/
# - macOS: src-tauri/target/release/
# - Windows: src-tauri/target/release/

Platform-Specific Build Options

Debug Build (faster compilation, larger binary)
```
bun run tauri build --debug
```
Universal Binary for macOS (Intel + Apple Silicon)

Troubleshooting

Common Issues

"cargo not found" error
- Ensure Rust is installed and ~/.cargo/bin is in your PATH
- Run source ~/.cargo/env or restart your terminal
Linux: "webkit2gtk not found" error
- Install the webkit2gtk development packages listed above
- On newer Ubuntu versions, you might need libwebkit2gtk-4.0-dev
Windows: "MSVC not found" error
- Install Visual Studio Build Tools with C++ support
- Restart your terminal after installation
"claude command not found" error
- Ensure Claude Code CLI is installed and in your PATH
- Test with claude --version
Build fails with "out of memory"
- Try building with fewer parallel jobs: cargo build -j 2
- Close other applications to free up RAM

Verify Your Build

After building, you can verify the application works:

# Run the built executable directly
# Linux/macOS
./src-tauri/target/release/opcode

# Windows
./src-tauri/target/release/opcode.exe
