There are two different sets of packages for Linux:
- the Qt 5 based packages for all modern Linux distributions ( /
- the Qt 4 based legacy packages for older Linux distributions (,

The Qt 5 based packages are recommended for most modern Linux distributions and support DXF/DWG <= 2018 (DXF/DWG R32).

The Qt 4 based packages are recommended only for older Linux distributions if the Qt 5 based version does not work due to incompatible gcc libraries. These packages only support DXF/DWG <= 2013 (DXF/DWG R27).
