HOW TO BUILD DATA CATCHER ? 

Following gives the procedure steps to obtain the data catcher source 
and build under epics/extensions directory. 

It is assumed that you already have epics/config, epics/extensions
directory intact.

1.  Go to the directory where down loaded tar file should reside

    	cd epics/extensions    

2.  Unzip and extract sources from the tar file

	gunzip Catcher2_2c.Tar.gz
	tar xvf Catcher2_2c.Tar

3. Build the data catcher

    cd src
    gnumake

  Note: If building on sun4 make sure that the 
	 SPECIAL_LANG = /usr/lang/SC2.0.1patch 
	 is set in the CONFIG_SITE.Unix.sun4 in the epics/config directory




HOW TO TEST DATA CATCHER ? 

Test the data catcher, make sure the /usr/local/epics/extensions/bin/$HOST_ARCH 
is in your search path. 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
    cd
    catcher -D

where $HOST_ARCH is either solaris or sun4.
