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?

我在ubuntu上工作14.04 LTS与PHP 5.5.9 启用GD并且我加倍检查 但仍显示 每当我尝试使用imagecreatefromjpeg()



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

它让我回来了 bool(false)

无论如何都有 修复此问题而不重新编译它?

    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:

    Try this
    function LoadJpeg($imgname)
        /* Attempt to open */
        $im = @imagecreatefromjpeg($imgname);
        /* See if it failed */
            /* 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');

    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
