Requirements and compilation

The workflow supports in DIET needs the following:

• The Xerces library: the XML handling code is written with Xerces-C++ using the provided DOM API.
• The XQilla library: the conditions in conditional or looping workflow structures are written in XQuery language and parsed using the XQilla library.
• Enable the workflow support when compiling DIET. In order to build DIET with workflow support using cmake, three configuration parameters need to be set:
  • DIET_USE_WORKFLOW as follow: -DDIET_USE_WORKFLOW:BOOL=ON
  • XERCES_DIR: defines the path to Xerces installation directory. (e.g., -DXERCES_DIR:PATH=/usr/local/xerces)
  • XQILLA_DIR: defines the path to XQilla installation directory. (e.g., -DXQILLA_DIR:PATH=/usr/local/xqilla)

  N.B. 1:By activating the workflow module, the DAGDA module is also activated.

  This is an example of generating command line:

  cmake .. -DMAINTAINER_MODE:BOOL=ON -DOMNIORB4_DIR=/usr/local/omniORB \

  -DDIET_USE_WORKFLOW:BOOL=ON \

  -DXERCES_DIR=/usr/local/xerces

  -DXQILLA_DIR=/usr/local/xqilla
