Re: [Axiom-developer] Hyper doc search error

Hello Tim,

[ about the correct path to awk binary ]
> i'm open to suggestions about how to fix this.

A suggestion: use a ./configure that look for those binaries and write
the Makefile.

Suggestion for the one who would like to tackle this issue: you'll
find in 
http://www.linux-france.org/~dmentre/demexp/latest-src/demexp--dev--0.7.tar.gz
a configure script written from scratch. It is under GPL license but,
as the unique author of that code, I give permission to any coder of
Axiom project to reuse it under Axiom's BSD-like license.

----searchpath shell script (don't know where it comes from)------
#!/bin/sh
# Find a program in the path

IFS=':'
for dir in $PATH; do
  if test -z "$dir"; then dir=.; fi
  if test -f $dir/$1; then exit 0; fi
done
exit 1
-----------------------

It could be used like this:

# do we have ocaml?
echo -n "Looking for ocamlc... "
if sh ./searchpath ocamlc; then
    echo "found";
else
    echo "not found";
    echo "*** OCaml compiler is required for compilation";
    echo "*** Please install the package or compile following
instructions found";
    echo "*** in README. Source archive available at";
    echo "***   http://caml.inria.fr/ocaml/distrib.html";;
    exit 2;
fi

It would be better if searchpath would return the found path. Here is
a modified searchpath that does this :

#!/bin/sh
# Find a program in the path and prints its location if found

IFS=':'
for dir in $PATH; do
  if test -z "$dir"; then dir=.; fi
  if test -f $dir/$1; then echo $dir/$1; exit 0; fi
done
exit 1


It should be used like this:

#!/bin/sh

# do we have awk?
echo -n "Looking for awk... "
awk_path=`./searchpath awk`
if [ $? == 0 ]; then
    echo "found: $awk_path";
else
    echo "not found";
    echo "*** Awk is required for compilation";
    echo "*** Please install it";
    exit 2;
fi


I hope it helps,
Best wishes,
d.
