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.

Augmentez les possibilités des GD de gérer d'autres formats d'images en spécifiant les options --with-XXXX de compilation suivantes :

Formats d'image supportés
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.
webp Pour activer la prise en charge de WebP, ajoutez --with-vpx-dir=DIR . Disponible à partir de PHP 5.5. A partir de PHP 7.0.0 --with-webp-dir=DIR a été ajouté. La prise en charge de libvpx a été supprimé pour libwebp.

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 :

Bibliothèques des polices de caractères supportées
Bibliothèque Option de configuration
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] (Supprimé depuis PHP 7.0.0).
Chaînes TrueType Pour activer le support des chaînes de caractères TrueType, ajoutez l'option --enable-gd-native-ttf . (Inefficace depuis PHP 5.5.0; supprimé à partir de PHP 7.2.0.)

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

Once you have installed php-gd, don't forget to restart the Apache server using the following command:

    sudo service httpd restart

I struggled needlessly for over an hour trying to figure out why it wouldn't work after I had installed the packages along with all their dependencies.  :-)

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

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.

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.

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!

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).
