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

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

2. Install Static Libraries

# 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

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

Building

Development Build

npm run tauri-dev

Production Build (Single .exe)

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.
