well i've added some lines in robot_functions.php to find the problem. here they are :
echo $command . "<br>"; // try running this from shell in admin dir
print_r($result); // holds the output sent to STDOUT
echo "<br>" . $retval; // is zero if command succeeded
and when spidering comes through a pdf, a doc or a xls file, I can read this :
/usr/opt/www/juju/catdoc/bin/catdoc -s 8859-1 ../admin/temp/53771962.tmp
Array ( )
so it appears it returns nothing, even for pdf files (i had believed that it works for pdf files because of the green quote but actually it seems it doesn't)
its very strange, maybe the temp files aren't created ?
