Hello,

Questions with regards to compiling PHP to support GD with JPEG on 64-bit CentOS 5.5.

1) Specifying folder for jpeg library
When I execute the following command, am I saying the full path to libdir is at /usr/source/lib64?
../configure --with-apxs2=/usr/local/apache2/bin/apxs --with-gd --with-jpeg-dir=/usr/source --with-libdir=lib64

Should I have done the following instead?
../configure --with-apxs2=/usr/local/apache2/bin/apxs --with-gd --with-jpeg-dir=/usr/source/lib64


2) After copying the compiled JPEG libraries to the the lib64 directory, PHP is still unable to call the GD functions (ie ImageCreateFromJpeg) properly.
Once I've done the following.
../configure --enable-shared
make
make install

I have the following files installed. Meanwhile the /usr/local/lib64 directory doesn't have these files. Despite copying the whole set to /usr/local/lib64, the above configure command still doesn't work.
/usr/local/lib/libjpeg.a
/usr/local/lib/libjpeg.la
/usr/local/lib/libjpeg.so -> libjpeg.so.8.0.2
/usr/local/lib/libjpeg.so.8 -> libjpeg.so.8.0.2
/usr/local/lib/libjpeg.so.8.0.2

The following displays a blank page on my Firefox.
header('Content-Type: image/jpeg');
$image_file_path = '/usr/local/apache2/htdocs/image.jpg';
$image_file_path";
$im = @ImageCreateFromJpeg($image_file_path)";
echo "$im";
imagejpeg($im);
echo "End: imagedestroy($im)";
?>

Hi Mike,
Dont know about your server config, but maybe try using this create
image script and see.

function create_image()
{
//Let's generate a totally random string using md5
$md5_hash = md5(rand(0,999));
//We don't need a 32 character long string so we trim it down to 5
$security_code = substr($md5_hash, 15, 5);

//Set the session to store the security code
$_SESSION["security_code"] = $security_code;

//Set the image width and height
$width = 100;
$height = 20;

//Create the image resource
$image = ImageCreate($width, $height);

//We are making three colors, white, black and gray
$white = ImageColorAllocate($image, 255, 255, 255);
$black = ImageColorAllocate($image, 0, 0, 0);
$grey = ImageColorAllocate($image, 204, 204, 204);

//Make the background black
ImageFill($image, 0, 0, $black);

//Add randomly generated string in white to the image
ImageString($image, 3, 30, 3, $security_code, $white);

//Throw in some lines to make it a little bit harder for any
bots to break
ImageRectangle($image,0,0,$width-1,$height-1,$grey);
imageline($image, 0, $height/2, $width, $height/2, $grey);
imageline($image, $width/2, 0, $width/2, $height, $grey);

//Tell the browser what kind of file is come in
header("Content-Type: image/jpeg");

//Output the newly created image in jpeg format
ImageJpeg($image);

//Free up resources
ImageDestroy($image);
}

Was taken from the WebCheatSheet.com - Create CAPTCHA Protection.
Namely to see how they are using the ImageJpeg, not the whole code.
But, at least you will have a code you know produces an image if
anything and
you can shorten the things on the list to check. ;)

Just tried it with the following but still fails. All I'm getting is a blank page.

function create_image()
{
//Let's generate a totally random string using md5
$md5_hash = md5(rand(0,999));
//We don't need a 32 character long string so we trim it down to 5
$security_code = substr($md5_hash, 15, 5);

//Set the session to store the security code
$_SESSION["security_code"] = $security_code;

//Set the image width and height
$width = 100;
$height = 20;

//Create the image resource
$image = ImageCreate($width, $height);

//We are making three colors, white, black and gray
$white = ImageColorAllocate($image, 255, 255, 255);
$black = ImageColorAllocate($image, 0, 0, 0);
$grey = ImageColorAllocate($image, 204, 204, 204);

//Make the background black
ImageFill($image, 0, 0, $black);

//Add randomly generated string in white to the image
ImageString($image, 3, 30, 3, $security_code, $white);

//Throw in some lines to make it a little bit harder for any bots to break
ImageRectangle($image,0,0,$width-1,$height-1,$grey);
imageline($image, 0, $height/2, $width, $height/2, $grey);
imageline($image, $width/2, 0, $width/2, $height, $grey);

//Tell the browser what kind of file is come in
header("Content-Type: image/jpeg");

//Output the newly created image in jpeg format
ImageJpeg($image);

//Free up resources
ImageDestroy($image);
}

create_image();

Re: Configuring PHP with GD and JPEG support

Hey Mike,
A google search for "PHP is unable to call the GD function" reveiled
some interesting results. Have a look see.

Best,
Karl
