sudo apt-get install php5-gd && sudo service apache2 restart
To install under Ubuntu 14.04.
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, 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.
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. |
| webp | To enable support for webp add --with-vpx-dir=DIR . Available as of PHP 5.5. As of PHP 7.0.0 --with-webp-dir=DIR has to be added, i.e. support for libvpx has been removed in favor of libwebp. |
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] (Removed as of PHP 7.0.0). |
| Native TrueType string function | To enable support for native TrueType string function add --enable-gd-native-ttf . (Effectless as of PHP 5.5.0; removed as of PHP 7.2.0.) |

Instructions how to compile bundled version on Linux:
http://stackoverflow.com/questions/35560150/php-gd-bundled-extension-without-recompiling-php-solution
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
I also had to install the libgd package in addition to php5-gd:
sudo apt-get install libgd2-xpm-dev*
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).
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 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-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. :-)
#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

I was having a gdImageCreateFromJpegCtx undefined symbol....
the solution was found in here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=470483
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'
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 Macox lion with mac port just use:
sudo port install php5-gd
I installes php5-gd by adding
deb http://ftp.de.debian.org/debian sid main
in /etc/apt/sources.list
then
apt-get install php5-gd
then i have troubles for starting apache2 but google find all troubles ...
cd /etc/apache2
mkdir conf.d
changes in apache2.conf :
replace
LockFile ${APACHE_LOCK_DIR}/accept.lock
by
Mutex file:${APACHE_LOCK_DIR} default
comment lines NameVirtualHost (with a #)
a2enmod suexec (correction Suexec....)
a2enmod rewrite (correction erreur dav)
a2enmod dav_fs (correction erreur filesystem)
service apache2 start
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.
While it is true that you can install GD with apt, that version comes without some of the traits of the internal, compiled version.
I noticed that when I tried to call method `imageantialias`
