cron: ln -s apps/images_ocr/tess is not a directory

[jlaba]

The cron script echos the error above. I think the relative path to apps/images_ocr is not correct, when called with system cron. Currently I'm not able to figuring out the correct path, but introduced an extra check in app.php, to make sure the path is an existing directory, which might be useful in generall (s. first line of code, which is line 85 in app.php):

    if (is_dir('apps/images_ocr') && !file_exists('apps/images_ocr/tess')) {
        $depth = 1;

        while ($depth < MAX_DEPTH_CHECK) {
            $depth += 1;
            exec('find / 2>/dev/null -maxdepth '.$depth.' -name "tessdata" -type d', $result);
            printf($result);
            if ($result != null && strlen($result[0]) > 0) {
                exec('ln -s '.$result[0].' apps/images_ocr/tess');
                break;
            }
        }
    }
