# Static Build Configuration for Windows

This configuration builds EU-Utility V3 as a single .exe file with all OCR libraries statically linked.

## Prerequisites

### 1. Install vcpkg

```powershell
git clone https://github.com/Microsoft/vcpkg.git C:\vcpkg
C:\vcpkg\bootstrap-vcpkg.bat
C:\vcpkg\vcpkg integrate install
```

### 2. Install Static Libraries

```powershell
# Install Tesseract and dependencies as static libraries
C:\vcpkg\vcpkg install tesseract:x64-windows-static-md
C:\vcpkg\vcpkg install leptonica:x64-windows-static-md
C:\vcpkg\vcpkg install libpng:x64-windows-static-md
C:\vcpkg\vcpkg install tiff:x64-windows-static-md
C:\vcpkg\vcpkg install libjpeg-turbo:x64-windows-static-md
```

**Note:** This takes 30-60 minutes on first run.

### 3. Set Environment Variables

```powershell
$env:VCPKG_ROOT = "C:\vcpkg"
$env:VCPKGRS_DYNAMIC = "0"
```

## Building

### Development Build
```powershell
npm run tauri-dev
```

### Production Build (Single .exe)
```powershell
npm run tauri-build
```

The output will be:
- `src-tauri/target/release/bundle/msi/*.msi` - Windows installer
- `src-tauri/target/release/eu-utility-v3.exe` - Standalone executable

## Build Size

- **Without OCR:** ~15MB
- **With OCR (static):** ~80-120MB

## Distribution

The .msi installer includes everything needed:
- Main application (single .exe)
- WebView2 runtime (if not present)
- Start menu shortcuts

Users do not need to install Tesseract separately.
