Installation instructions for the Evidence Data Display Edd

A) The packages Qt, Qwt and DIM are needed

1. Qt can be downloaded from http://qt.nokia.com/. 

   Test have been made with version 4.6.2 which can be downloaded aat
   ftp://ftp.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.6.2.tar.gz.
   It should well work with later version as well. 
   
   Installation instruction are given in the package. Usually, they amount on
   Linux to executing './configure', then 'gmake all' followed by 
   'gmake install', all done within the unpacked directory.
 
   Before the following steps, it should be assured that the right version
   of qmake is used, as many Linux installations include an older version
   of Qt. Use 'qmake -version' to check and adjust your PATH variable if
   necessary.
    
2. Qwt can be downloaded from http://sourceforge.net/projects/qwt/.
   
   Tests were made with version 5.2.1. Installation should simply be done
   by executing 'qmake', then 'make', and finally 'make install'.

3. DIM can be downloaded from http://dim.web.cern.ch/dim/.

   The latest available version should be fine. Follow the installation
   instruction on the web site given at the download link. Note that the
   command line option in 'unzip -a' is mandatory. Compiling is done
   with 'gmake all'.


B) Compiling Edd

An environment variable QWTDIR should point to the Qwt installation,
and DIMDIR to the DIM installation.

Issue 'qmake', then 'make' will build the executable Edd.

To start, the environment variable LD_LIBRARY_PATH needs to include the
location of the Qwt shared library.
