Pré-requis
CentOS 6
yum install php-gd
worked, no need to recompile.
Installation
Pour activer le support de GD, vous devez compiler PHP avec l'option --with-gd[=DIR] , où DIR est le dossier d'installation de GD. Il est recommandé d'utiliser la version de GD qui est distribuée avec PHP, en utilisant simplement l'option --with-gd . La bibliothèque GD requiert libpng et libjpeg pour compiler.
Sous Windows, vous devez inclure la bibliothèque php_gd2.dll comme extension dans le fichier php.ini. La bibliothèque php_gd.dll a été supprimée de PHP 4.3.2. Notez aussi que les fonctions conseillées truecolor, comme imagecreatetruecolor(), requièrent GD2.
Augmentez les possibilités des GD de gérer d'autres formats d'images en spécifiant les options --with-XXXX de compilation suivantes :
| Format d'image | Option de compilation |
|---|---|
| jpeg | Pour activer le support de la bibliothèque JPEG, ajouter l'option --with-jpeg-dir=DIR . Jpeg 6b, 7 ou 8 est supporté. |
| png | Pour activer le support de la bibliothèque PNG, ajouter l'option --with-png-dir=DIR . Notez que libpng requiert la bibliothèque zlib et, donc, il vous faudra ajouter aussi --with-zlib-dir[=DIR] dans votre ligne de compilation. |
| xpm | Pour activer le support de la bibliothèque XPM, ajoutez l'option --with-xpm-dir=DIR . Si le script de compilation n'est pas capable de trouver les bibliothèques nécessaires, il vous faudra ajouter le chemin vers les bibliothèques X11. |
Note: Lorsque vous compilez PHP avec libpng, vous devez utiliser la même version que celle liée à la bibliothèque GD.
Augmentez les possibilités de GD pour qu'elle manipule différents types de polices de caractères en ajoutant les options --with-XXXX de compilation suivantes :
| Bibliothèque | Option de configuration |
|---|---|
| FreeType 1.x | Pour activer le support de FreeType 1.x, ajoutez l'option --with-ttf[=DIR] . |
| FreeType 2 | Pour activer le support de FreeType 2, ajoutez l'option --with-freetype-dir=DIR . |
| T1lib | Pour activer le support de T1lib (Postscript Type 1 fonts), ajoutez l'option --with-t1lib[=DIR] . |
| Chaînes TrueType | Pour activer le support des chaînes de caractères TrueType, ajoutez l'option --enable-gd-native-ttf . |

Running a Debian Squeeze server, all I had to do to add support for GD to my Apache server was simply run `apt-get install php5-gd` and then restart Apache. No recompiling or reconfiguring or anything. Simple!

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.

I also had to install the libgd package in addition to php5-gd:
sudo apt-get install libgd2-xpm-dev*

I 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!

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-gd

In Slackware 64bit (I tested 13.1) you need to make symlinks to libpng and libjpeg if you want to compile php with GD, even if you've already installed them, otherwise configure will give you a "libpng not found" error, even if you set --with-libdir=/usr/lib64 (it seems to have no effects at all). So, run these before configuring:
ln -s /usr/lib64/libjpeg.so /usr/lib/libjpeg.so
ln -s /usr/lib64/libpng.so /usr/lib/libpngp.so

If you have already compiled PHP and want to recompile '--with-gd', don't forget to run 'make clean' first!

On 64bit centos, needed to create links from lib64 to lib. Php seems to insist on looking in lib, even with "with-jpeg-dir" config.
Eg
ln -s /usr/lib64/libjpeg.so.62.0.0 /usr/lib/libjpeg.so
ln -s /usr/lib64/libpng.so.3.10.0 /usr/lib/libpng.so
./configure \
--with-config-file-path=/etc \
--prefix=/usr \
--with-bz2 \
--enable-zip \
--enable-mbstring \
--with-apxs2=/usr/sbin/apxs \
--with-zlib-dir=/usr/include \
--with-libxml-dir=/usr/lib64 \
--with-mcrypt=/usr/lib64 \
--with-mysql \
--with-gd \
--with-jpeg-dir=/usr \
--with-png-dir=/usr \
--enable-calendar

If you have already compiled php without jpeg support and decide you want it , then before you compile again you might need to run "make clean" first.

For Redhat Linux 64 bit machine:
--with-libdir=lib64 --with-gd --with-jpeg-dir --with-png-dir

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

On my system,I had to ensure I had not only libpng and libjpeg, but also the libpng-devel and libjpeg-devel packages installed.

Everytime I try to install the gd-lib as a dynamic extension, I run into the same problem: It wont work.
I get the following error:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/pkg/lib/php/20040412/gd.so' - dlopen(/usr/pkg/lib/php/20040412/gd.so, 9): Symbol not found: __cg_jpeg_resync_to_restart\n Referenced from: /System/Library/Frameworks/ApplicationServices. framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/ImageIO\n Expected in: /usr/pkg/lib/libjpeg.62.dylib\n in Unknown on line 0
I use pkgsrc for software package managment on my mac, as may be apparent from the paths.
The solution is, to edit the file /usr/pkg/sbin/envvars and remove or comment the DYLD_LIBRARY_PATH because it is causing the error...

jpeg [jpg] file processing doesn't work unless you build php with '--with-jpeg-dir=<path to jpeg library>'.
It still doesn't work unless <path to jpeg library> points to the directory holding the directory holding the library unless libjpeg.<whatever> is in either /usr/lib or /usr/local/lib. For instance, on a mac with libjpeg.a installed via mac ports, you need '/opt/local' rather than '/opt/local/lib'
