How do I enable GD?

What does PHP GD do?

i checked the phpinfo() its there and it is enabled.

I tired to see if there is anything that i can add on the php.ini but i couldn't find any. The error is thrown when i call

gd_info();

Is there anything that i can add on the php.ini file that can solve this problem, or is there another library for gd?

The error am getting is the following

Fatal error: Call to undefined function gd_info(

I had exactly the same problem

although I had installed it using apt-get install php7.0-gd that function was undefined, so I inspected php.ini file in /etc/php/7.0/apache2/php.ini

turned out that the line for gd extension was commented!

so I removed semicolon before the line and it was working!

so crazy wasted an half an hour of mine :D

It may be a little bit late, but I hope it helps anyone.

I had the same problem when I tried to run GD over apache. The problem was in php.ini path for apache. By default it is not using php.ini from php directory. You need to define PHPIniDir in httpd file or place copy of php.ini to apache folder.

To check if it is your case you can compare output of php --ini from php folder and output of phpinfo() over apache. If it is showing different php.ini destinations you need to fix it.

Logged in as root, I installed the php-gd libraries using

$ yum install php-gd

it said everything worked fine, so i did

$ /etc/init.d/nginx restart

But the code I had been working on still complained of not having the gd libraries and when I went to check the output of phpinfo there was no 'gd' section.

I should note that yum list | grep gd shows

gd.i386  2.0.33-9.4.el5_1.1  installed
gd-devel.i386  2.0.33-9.4.el5_1.1  installed
gdb.i386  6.8-27.el5  installed
gdbm.i386  1.8.0-26.2.1  installed
php-gd.i386  5.1.6-23.2.el5_3  installed

I also added extension=gd.so manually to /etc/php.ini and it is still not showing up or raising an error which leads me to believe my php.ini is not being re-parsed when I restart nginx. Is there something outside of restarting nginx I have to do to get php.ini changes loaded?

I have a fair amount (like 3 years) of ad-hoc server administration experience although no formal training, but I'm relatively new to nginx and have never worked with CentOS before, so any help would be much appreciated.

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.

Supported image formats

Image Format	Configure Switch
`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.

Supported font libraries

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.)

For all who use php 7 and ubuntu

sudo apt-get install php7.0-gd

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).

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

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!

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.

As of PHP 7.4, to enable GD you have to use --enable-gd instead of --with-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!
