Call to undefined function imagecreatefromjpeg() and GD enabled

Question

im working on ubuntu 14.04 LTS with PHP 5.5.9 with GD enabled and i doubled check with but still showing me this msg everytime i try to use imagecreatefromjpeg()

Fatal error: Call to undefined function imagecreatefromjpeg() in /../library/image.php on line 34

i even tried to check on it from command line by using this

php -r "var_dump(function_exists('imageantialias'));"

and it gives me back bool(false)

is there anyway to fix this without re compiling it?

From the documentation: JPEG support is only available if PHP was compiled against GD-1.8 or later. – Greensickness

looks like this one is a double: #13338839 – Bacteriolysis

i've tried every possible solution with that post and it didnt work out – Carl

OK, so why not trying this call: php -r "var_dump(function_exists('imagecreatefromjpeg'));"? Or try this var_dump(function_exists('imagecreatefromjpeg')); from within the file where this method should be used (and before it is called of course). – Bayles

How do you know gd is enabled? PHP from web and PHP from CLI might have different configurations. – Escobar

"var_dump(function_exists('imagecreatefromjpeg'));" returns true – Carl

i know its enabled cuz php --ri gd gd GD Support => enabled GD Version => 2.1.1-dev FreeType Support => enabled FreeType Linkage => with freetype FreeType Version => 2.5.2 GIF Read Support => enabled GIF Create Support => enabled JPEG Support => enabled libJPEG Version => 8 PNG Support => enabled libPNG Version => 1.2.50 WBMP Support => enabled XPM Support => enabled libXpm Version => 30411 XBM Support => enabled WebP Support => enabled – Carl

For ubantu 16.* use "sudo apt-get install php5.6-gd" – Muddleheaded

Answer 1

I think you've installed an incomplete version of gd.
When you compile the gd extension, use the flag --with-jpeg-dir=DIR and --with-freetype-dir=DIR

ps. dont forget make clean

picture below is the incomplete version of gd:

Make emphasis on "don't forget make clean". – Fianna

Answer 2

In my case, GD was missing after upgrading to PHP 7.3. So, I just added it by using the following command :

sudo apt-get install php7.3-gd

Answer 3

Find php.ini generally C:\xampp\php (in windows system) then open php.ini

1. find extension=gd
2. Uncomment (remove ; from the start of the line)
3. Stop Xampp and start

Hope will work as here it's working!

Try this
<?php
function LoadJpeg($imgname)
{
    /* Attempt to open */
    $im = @imagecreatefromjpeg($imgname);

    /* See if it failed */
    if(!$im)
    {
        /* Create a black image */
        $im  = imagecreatetruecolor(150, 30);
        $bgc = imagecolorallocate($im, 255, 255, 255);
        $tc  = imagecolorallocate($im, 0, 0, 0);

        imagefilledrectangle($im, 0, 0, 150, 30, $bgc);

        /* Output an error message */
        imagestring($im, 1, 5, 5, 'Error loading ' . $imgname, $tc);
    }

    return $im;
}

header('Content-Type: image/jpeg');

$img = LoadJpeg('bogus.image');

imagejpeg($img);
imagedestroy($img);
?>
