Installation
To enable GD-support configure PHP --with-gd[=DIR] , where DIR is the GD base install directory. To use the recommended bundled version of the GD library (which was first bundled in PHP 4.3.0), use the configure option --with-gd . GD library requires libpng and libjpeg to compile.
In Windows, you'll include the GD2 DLL php_gd2.dll as an extension in php.ini. The GD1 DLL php_gd.dll was removed in PHP 4.3.2. Also note that the preferred truecolor image functions, such as imagecreatetruecolor(), require GD2.
Enhance the capabilities of GD to handle more image formats by specifying the --with-XXXX configure switch to your PHP configure line.
| Image Format | Configure Switch |
|---|---|
| jpeg | To enable support for jpeg add --with-jpeg-dir=DIR . Jpeg 6b, 7 or 8 are supported. |
| png | To enable support for png add --with-png-dir=DIR . Note, libpng requires the zlib library, therefore add --with-zlib-dir[=DIR] to your configure line. |
| xpm | To enable support for xpm add --with-xpm-dir=DIR . If configure is not able to find the required libraries, you may add the path to your X11 libraries. |
Note: When compiling PHP with libpng, you must use the same version that was linked with the GD library.
Enhance the capabilities of GD to deal with different fonts by specifying the --with-XXXX configure switch to your PHP configure line.
| Font library | Configure Switch |
|---|---|
| FreeType 2 | To enable support for FreeType 2 add --with-freetype-dir=DIR . |
| T1lib | To enable support for T1lib (Postscript Type 1 fonts) add --with-t1lib[=DIR] . |
| Native TrueType string function | To enable support for native TrueType string function add --enable-gd-native-ttf . |

It should be noted that it might be pretty easy to install gd without the need to recompile php, when using debian:
apt-get install php5-gd
If you have already compiled PHP and want to recompile '--with-gd', don't forget to run 'make clean' first!To get GD bundled under Ubuntu, the way to recompile php5 with gd is described here (french) http://doc.ubuntu-fr.org/modules_php#php5-gdI was running PHP on a SUSE box on amazon EC2.
to get gd to work all I had to do was to run:
> yast -i php5_gd
and when that completed I just restarted apache. voila!
I also had to install the libgd package in addition to php5-gd:
sudo apt-get install libgd2-xpm-dev*
People having difficulties setting the --with-libdir option needs to set it like this :
--with-libdir=lib64
That option works fine. Doing --with-libdir=/usr/lib64 doesn't work because the configure script prepends the --prefix option before the --with-libdir option. So, doing --with-libdir=/usr/lib64 makes the configure script to look for libs in /usr/usr/lib64, which is wrong of course, and not in /usr/lib64.
On Macox lion with mac port just use:sudo port install php5-gd
sudo apt-get install php5-gd && sudo service apache2 restart
To install under Ubuntu 14.04.
If you are using PHPBREW , the extension is called gd.
So you do.
```
phpbrew ext install gd
```
It will compile the extension to the core.

On Ubuntu I was missing the libpng-dev, libjpeg-dev (and in my case) libwebp-dev libraries, all gettable with apt-get.
Also once those libraries are installed, including --with-png-dir --with-jpeg-dir --with-webp-dir, without any values (i.e. =/dir) appeared to be valid ... though admittedly I didn't try without (in case the configure script autodetected them).
For all who use php 7 and ubuntu
sudo apt-get install php7.0-gd
To install on CentOS:
yum install php-gd
#install under Ubuntu 16.04:
* if you have access to PHP7.1:
<sudo> apt install php7.1-gd && <sudo> systemctl restart apache2
* if you have access to PHP7.0:
<sudo> apt install php7.0-gd && <sudo> systemctl restart apache2

On AntergosOS ( Arch linux )
*first run >>php -v and get current php version. In my case for PHP 7.1.14
sudo pacman -S php71-gd
then restart you apache server using,
sudo systemctl restart httpd
php --version if result is 7.2 version
sudo apt-get install php7.2-gd
To install PHP GD extension on an Amazon Linux AMI server, with php 7:
sudo yum install php 70-gd
Do remember to restart Apache after the installation!
sudo service httpd restart
Since 7.4 replace "--with-gd" by "--enable-gd"As of PHP 7.4, to enable GD you have to use --enable-gd instead of --with-gdcurrently is php7.2-gd
sudo apt install php7.2-gd
Hello. Does GD image processing allow for color spaces / color profiles to be defined or maintained from the source image? For example, if I upload a jpg with ProPhoto RGB color space with the embedded profile, will all of the subsequent processed images that are output maintain the profile? Or is there no profile and or is it changed to sRGB?
Same question goes for ImageMagick.
Thank you so much!
Installation on Pop-os No need for php5 or php7.0 etc:
sudo apt install php-gd
Note if you have php-fpm installed, you have to restart the service for the installation to show up in phpinfo output...
systemctl restart php-fpm (or equivalent)
