ConFoo Montreal 2017 Calling for Papers

Installation

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 (which was first bundled in PHP 4.3.0), 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. The GD1 DLL php_gd.dll was removed in PHP 4.3.2. Also note that the preferred truecolor image functions, such as imagecreatetruecolor(), require GD2.

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.
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.

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 1.x To enable support for FreeType 1.x add --with-ttf[=DIR] .
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] .
Native TrueType string function To enable support for native TrueType string function add --enable-gd-native-ttf .

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!

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'

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).

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`

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.
