UNIX for Dummies Questions & Answers

Hi, I wonder if someone can help me with what is probably a very easy question.

I'm relatively new to UNIX and have recently been trying to get into it more since I bought a new Mac. I'm trying to run the dada engine (to generate random text based on rules) but I can't seem to get it to work. I've downloaded the source code, run ./configure, make and sudo make install. It's installed everything I need.

But when I try to run it - no output. I can make the pb program, which is the text generator, work fine if I include commands which don't involve the C preprocessor. The user interface, dada, contains the following code:

Code:

#!/bin/sh
# User interface/wrapper for the Dada Engine
# Author:    acb
# Commenced: 14-7-1995

PBDIR="/usr/local/bin"
DADAROOT="/usr/local/lib/dada"
CPP=""

#CPP="/lib/cpp"
#CPPARGS="-lang-c++"
FILES=""
#PB="`dirname $0`/pb"
#INCLUDE="-I`dirname $0`/include -I$DADAROOT/include"
PB="${PBDIR}/pb"
INCLUDE="-I${DADAROOT}/include"

while test $# -gt 0
do
  case $1 in
    -D*) CPPARGS="$1 $CPPARGS";;
    -o) PBARGS="$PBARGS $1 $2"; shift;;
    -p) PBARGS="$PBARGS $1";;
    -r) PBARGS="$PBARGS $1 $2"; shift;;
    -s) PBARGS="$PBARGS $1 $2"; shift;;
    -w) PBARGS="$PBARGS $1 $2"; shift;;
    *) CPPARGS="$CPPARGS $1";;
  esac
  shift
done

($CPP $INCLUDE $CPPARGS 2>/dev/null) | $PB $PBARGS

I'm sure there must be a problem with a path in there somewhere or something. /lib/cpp doesn't exist on my machine, for example, but I tried changing this to the location of cpp (/usr/bin/cpp) but still no output.

Sorry for the length of the post, it's just frustrating to try and work this out!

Thanks for your time.

OK, I seem to have partially solved the problem. But there are still some things going wrong.

By changing line 8 to CPP="/usr/bin/cpp" and leaving line 10 as it is, dada now seems to pipe things through pb the way it is supposed to. But various things don't work: in particular, some of the test programs and included scripts aren't working properly. Sometimes they quite because of an unrecognised variable, and sometimes I just get a runtime error before the script is even piped to pb (e.g. pomo.pb).

Any help would be greatly appreciated.

Bump.

It'd be great if someone could give me a hand with this. Please?
