Hello again - So I don't know how you guys pull CMTK sources, but I just published a new release with the DCMTK compile errors fixed.
Download here: https://www.nitrc.org/frs/download.php/11132/CMTK-3.3.1p1-Source.tar.gz Or from SVN at NITRC via https://nitrc.org/svn/cmtk/releases/3.3.1p1 Best, Torsten
