Overview

Step 2 downloads all required third-party library source code from various repositories. This includes DCMTK, VTK, ITK, and numerous support libraries. Patches are automatically applied where necessary.
This is a once-only operation. You only need to download sources once unless you’re updating to new library versions.

​
What Gets Downloaded

The download step retrieves source archives for:
  • DCMTK - DICOM Toolkit (with Miele-LXIV patches)
  • VTK - Visualization Toolkit
  • ITK - Insight Segmentation and Registration Toolkit
  • OpenJPEG - JPEG 2000 codec (with patches)
  • OpenSSL - Cryptography library
  • libjpeg - JPEG image library
  • libpng - PNG image library
  • libtiff - TIFF image library
  • libxml2 - XML parsing library
  • libiconv - Character encoding conversion
  • zlib - Compression library
  • GLEW - OpenGL Extension Wrangler Library (optional)
  • GLM - OpenGL Mathematics library (optional)
  • Jasper - Image processing library
  • Miele-LXIV - The main application source code

​
Running the Download

1

Open the configuration menu

From your $EASY_HOME directory, run:
./reconfigure.sh
This launches the kconfig-mconf interface.
2

Enable 'Download sources'

In the configuration menu:
  1. Navigate to “Download sources”
  2. Press Space to enable it (it should show [*])
  3. Optionally, enter the submenu to select which specific libraries to download (all are enabled by default)
  4. Disable all other steps (Configure, Build, Install, etc.) if they’re enabled
3

Save and exit

  1. Select Save
  2. Confirm with Ok
  3. Select Exit
  4. Confirm Exit again Download configuration
4

Execute the download

Run the build script to perform the downloads:
./build.sh
The script will download each library’s source archive and extract it to your configured SRC directory.

​
Expected Output

As the script runs, you’ll see output like: 
SRC: /path/to/your/sources
BLD: /path/to/your/build
BIN: /path/to/your/install

​
Patches Applied

Some libraries receive Miele-LXIV specific patches:
  • DCMTK: Custom modifications for Miele-LXIV integration
  • OpenJPEG: Compatibility patches
Patches are located in the patch/ directory and are applied automatically during the download step.

​
Download Sources

Libraries are downloaded from:
  • DCMTK: OFFIS DICOM server (dicom.offis.de)
  • VTK/ITK: Kitware repositories
  • OpenJPEG: uclouvain GitHub
  • Image libraries: Official project sites
  • Miele-LXIV: GitHub repository

​
Directory Structure After Download

Your SRC directory will contain: 
$SRC/
├── dcmtk-3.6.x/
├── VTK-9.x.x/
├── InsightToolkit-5.x.x/
├── openjpeg-x.x.x/
├── openssl-x.x.x/
├── libjpeg-x/
├── libpng-x.x.x/
├── libtiff-x.x.x/
├── libxml2-vx.x.x/
├── libiconv-x.x/
├── zlib-x.x.x/
└── miele-easy-x.x.x/
Actual version numbers depend on your version set configuration from Step 1.

​
Download Time

Estimated time: 15-30 minutes depending on your internet connection Total download size is approximately 500MB-1GB of compressed source archives.

​
Verification

Verify the downloads completed successfully: 
ls -la $SRC
You should see directories for each library listed above.

​
Troubleshooting

Install wget using Homebrew:
brew install wget
  • Check your internet connection
  • Some corporate networks may block certain download sites
  • Try running the download step again - it will skip already downloaded files
This usually means:
  • The source version doesn’t match the patch
  • The patch was already applied
Check the console output for specific patch errors.

​
What’s Next

Important: Do NOT run the download step again unless you’re intentionally updating library versions. Re-downloading will overwrite any patches that were applied.

Step 3: Build and Install

With all sources downloaded, you’re ready to compile and install the libraries.
