Fatal error: The command did not produce any output.

[ghost]

Hello buddy. How can I solve this problem?

My Code:

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

require_once '../../../vendor/autoload.php';

use thiagoalessio\TesseractOCR\TesseractOCR;

$executable='/home/***/webapps/pub/thiagoalessio/tesseract_ocr';
$dir = $executable.'/temp_php';

if( chmod($dir, 0777) )
{
    
    echo (new TesseractOCR('text.png'))
        ->executable($executable)
        ->tempDir($dir)
        ->run();
    
         
    chmod($dir, 0755);
    
}
else
{
    echo "Couldn't do it.";
}

And the result:

Fatal error:
Uncaught thiagoalessio\TesseractOCR\UnsuccessfulCommandException: Error! The command did not produce any output.

Hi @MabutasGroup , $executable='/home/***/webapps/pub/thiagoalessio/tesseract_ocr'; is not the executable you need ... what my library provides is only a convenient way of generating valid tesseract commands, but you still need the real tesseract installed on your server: https://github.com/tesseract-ocr/tesseract
and the real tesseract is what you should put in executable ;D

Since this is a usage question rather than a bug on the library, I'm going to close this and invite you to join https://gitter.im/thiagoalessio/tesseract-ocr-for-php in case you have further questions, sound good ?

Thank you for your responding.

tesseract-ocr/tesseract#751
It seems Blacklist and whitelist no longer work in 4.00alpha. They used to work in 3.04.
If I want to use them, I should downgrade to tesseract 3.04 ?
