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: 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 with the DIET_USE_WORKFLOW flags set (which can be done in a script or command line with -DDIET_USE_WORKFLOW:BOOL=ON).

  In case cmake is not able to locate the installation of the required libraries, you have to set:

  • XERCES_DIR which defines the path to Xerces installation directory,
    with -DXERCES_DIR:PATH=/usr/local/xerces for example.
  • XQILLA_DIR which defines the path to XQilla installation directory,
    with -DXQILLA_DIR:PATH=/usr/local/xqilla for example.

  N.B. 1:By activating the workflow module, the DAGDA module is also activated. N.B. 2:Workflow support is not available on Windows/Cygwin platforms (Windows XP and Cygwin 1.5.25) for Xerces 3.0.1 and XQilla 2.2.0.

  Here is an example of a generating command line:

  cmake ${path_to_diet_sources} \

  -DOMNIORB4_DIR=/usr/local/omniORB \

  -DDIET_USE_WORKFLOW:BOOL=ON \

  -DXERCES_DIR=/usr/local/xerces \

  -DXQILLA_DIR=/usr/local/xqilla
