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. As of PHP 7.4.0, --with-gd becomes --enable-gd (whether to enable the extension at all) and --with-external-gd (to opt into using an external libgd, rather than the bundled one).
In Windows, you'll include the GD DLL php_gd.dll as an extension in php.ini. Prior to PHP 8.0.0, the DLL was named php_gd2.dll.
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 |
|---|---|
avif |
To enable support for avif add --with-avif. Available as of PHP 8.1.0. |
jpeg |
To enable support for jpeg add --with-jpeg-dir=DIR. Jpeg 6b, 7 or 8 are supported. As of PHP 7.4.0, use --with-jpeg instead. |
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. As of PHP 7.4.0, --with-png-dir and --with-zlib-dir have been removed. libpng and zlib are required. |
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. As of PHP 7.4.0, use --with-xpm instead. |
webp |
To enable support for webp add --with-webp-dir=DIR. As of PHP 7.4.0, use --with-webp instead. |
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. As of PHP 7.4.0 use --with-freetype instead, which relies on pkg-config. |
Native TrueType string function |
To enable support for native TrueType string function add --enable-gd-native-ttf. (This option has no effect and has been removed as of PHP 7.2.0.) |
#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------------------------------------------------Qussayyon Qamaron: Qusai.zf2gmailcomPeople having difficulties setting the --with-libdir option needs to set it like this :--with-libdir=lib64That 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.Instructions how to compile bundled version on Linux:http://stackoverflow.com/questions/35560150/php-gd-bundled-extension-without-recompiling-php-solutionsudo apt-get install php5-gd && sudo service apache2 restartTo install under Ubuntu 14.04.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-gdphp --version if result is 7.2 versionsudo apt-get install php7.2-gdTo install PHP GD extension on an Amazon Linux AMI server, with php 7:sudo yum install php 70-gdDo remember to restart Apache after the installation!sudo service httpd restartI 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).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-gdInstallation on Pop-os No need for php5 or php7.0 etc:sudo apt install php-gdIf 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 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 httpdI 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_gdand when that completed I just restarted apache. voila!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)If you have already compiled PHP and want to recompile '--with-gd', don't forget to run 'make clean' first!
