HOW TO BUILD DATA CATCHER ?

It is assumed that you already have epics/extensions/config, and 
epics/extensions directories intact. This new config structure set up 
should allow the epics/extensions been built under any EPICS supported 
operating system. 

Following gives the procedure steps to obtain the data catcher source 
and build under epics/extensions directory. Step 1 is needed only if
the config.Tar.gz file has never been downloaded or the directory
epics/extensions/config never been created before. 

    1.  Go to epics/extensions/config directory and down load the  
	tar file config.Tar.gz

        Unzip and extract sources from the tar file

	gunzip config.Tar.gz
	tar xvf config.Tar

    2.  Go to epics/extensions directory and down load the tar file  
        Catcher2_2c9.Tar.gz

        Unzip and extract sources from the tar file

	gunzip Catcher2_2c9.Tar.gz
	tar xvf Catcher2_2c9.Tar

    3. Build the data catcher under unix operating system

	cd src/ezca
   	gnumake
	cd ../EzcaScan
   	gnumake
	cd ../ezcaIDL
   	gnumake
	cd ../idl
   	gnumake
	

HOW TO TEST DATA CATCHER ?

   Test the data catcher, make sure the /usr/local/epics/extensions/bin/$HOST_ARCH 
   is in your search path, where $HOST_ARCH is either solaris or sun4 
   for Unix system. The envrionment variable EPICS_EXTENSIONS must be
   set to /usr/local/epics/extensions.

   If the data catcher is built in your private epics extensions area, then 
   you need to set the EPICS_EXTENSIONS_PVT to point to your private area,
   e.g. 

	setenv EPICS_EXTENSIONS_PVT ~/epics/extensions
