Xindy and MiKTeX: empty raw index file

Question

I try to use xindy in MiKTeX. When I compile

\documentclass[a4paper]{article}
\usepackage{makeidx}
\makeindex
\begin{document}
test\index{test}\index{text}
\printindex
\end{document}

with

latex test.tex
texindy test.idx

it prints

C:/Program is not an internal command, external command, program or batch file.

Finished processing index.

Writing markup... [10%] [20%] [30%] [40%] [50%] [60%] [70%] [80%] [90%] [100%]
Markup written into file "test.ind".

The problem is that text.ind contains an empty theindex environment. Also, with the option -d kepp_tmpfiles I can see that the raw-index file is empty (the file zBpYoFHjX4above).

Note, the error/warning message C:/Program is not an internal command, ... from texindy.

I don't know if the following is related. If I try to compile xindy in Cygwin I get the error:

C:\Program Files (x86)\MiKTeX 2.9\scripts\xindy\texindy.pl: not a symlink as required for
TeX Live at C:\Program Files (x86)\MiKTeX 2.9\scripts\xindy\texindy.pl  line 423.

How to solve this?

Answer 1

It was not necessary to change texindy.pl. Please add a line

$filter=quotify($filter);

at the next line of line 719 of xindy.pl. After the change, sub filter_index becomes as follows:

sub filter_index ( $$ ) {
    my ($filter, $input) = @_;
    my $output = tmpnam();
    push (@temp_files, $output);
    $output=quotify($output);
    $filter=quotify($filter);
    print "Running filter: $filter <$input >$output\n"  if $verbose;
    system "$filter <$input >$output";
    print "filtered xindy input file: $output\n"  if $debug{script};
    return $output;
}
