Compile

• Download the latest version which will have a name such as NP330.Oct-26-2023.tgz
• Unpack in a subdirectory of your choice
• gunzip -c NP330.Oct-26-2023.tgz | tar xf -
• cd PROGRAMS.330
• ./Setup LINUX6440    (For the options, just enter ./Setup)
• ./C > C.txt  2>&1       (This is the compile and the C.txt will contain a lot of details. If the compile does not work,  look at the C.txt or Email it to the author)
• cd bin ; ls | wc           (This will indicate the number of programs compiled
• CAREFULLY edit the .profile or .bash_profile to add a line at the end that reads

• # set PATH so it includes CPS
  if [ -d "$HOME/PROGRAMS.330/bin" ] ; then
      PATH="$HOME/PROGRAMS.330/bin:$PATH"
  fi
  

  This assumes that PROGRAMS.330 was installed in the login directory. If it is placed somewhere else, then modify this line. If you have codes in ${HOME}/bin and if you want to easily use executables in the current directory, then also add at the bottom

PATH=:.:$HOME/bin:${PATH}

The revised path will be available on the next login or immediately in the terminal window if one enters

source ~/.profile    or     source ~/.bash_profile

• To test the installation, try this

• cd    (return to the login directory
  which gsac

  If you see something like /home/user/PROGRAMS.330/bin/gsac > then everything is ready to run
• NOTE:  the evalresp-5.0.1 from the EarthScope evalresp page (https://github.com/EarthScope/evalresp) uses  the "safer" strlcpy as a replacement for the standard strncpy routine. If the compile gives the warning such as this
  

       
   gcc (Ubuntu 11.4.0-ubuntu1-22.04) 11.4.0         
   [Note cc is symbolically linked to /usr/bin/gcc which is 11.4 here] 
               mxmldoc.c:658:3: warning: implicit declaration of function ‘strlcpy’; did you mean ‘strncpy’? [-Wimplicit-function-declaration]
                 658 |   strlcpy(temp->anchor, anchor, sizeof(temp->anchor));
                     |   ^~~~~~~ 
                     |   strncpy
        

  then carefully change the 11 instances of strlcpy( in mxmldoc.c to strncpy( and then return to PROGRAMS.330/IRIS and enter the command DOCOMPILE
