PHP4 and JPEG How To (was Re: GD 1.8.1/PHP RC1)

Hello, > I recently saw on the php.net site that support was added to PHP 4 RC1 for jpeg images > in the GD library. I have been trying for about 10 hours now to make it work and cannot. > specifically ImageCreateFromJpeg & ImageJpeg. OK. Here's how I sucessfully got JPEG working in PHP4 : 1) download gd ( http://www.boutell.com/gd/ ) 2) Decompress gd $tar xvzf gd-1.8.1.tar.gz 3) Edit gd's Makefile to fit your needs $cd gd-1.8.1/ $vi Makefile You've to tell gd that you want JPEG support in gd's Makefile : CFLAGS=-O -DHAVE_JPEG LIBS=-lm -lgd -lpng -lz -ljpeg Also check where the files will be installed, for example : INSTALL_LIB=/usr/local/lib/gd INSTALL_INCLUDE=/usr/local/include/gd 4) Compile gd $make (optionnal) check that JPEG support has been included in GD. $nm libgd.a | grep GD_JPEG_VERSION 00000004 r GD_JPEG_VERSION 5) Install gd $su #make install #exit 6) Configure PHP using your favorite options : $cd ../php4 $./configure --prefix=/usr \ --with-apxs=/usr/local/apache/bin/apxs \ --with-shared-apached=/etc/httpd \ --with-config-file-path=/usr/lib \ --with-regex=apache \ --without-pcre-regex \ --enable-debug=no \ --enable-versioning \ --enable-safe-mode \ --enable-track-vars \ ==> --with-gd=/usr/local \ ==> --with-jpeg-dir=/usr \ --with-ttf=/usr/lib Two notes : 1)"--with-gd=/usr/local" is used to find the following files : /usr/local/lib/gd/gd.a /usr/local/include/gd/gd*.h 2)"--with-jpeg-dir=/usr" is used to find the jpeg library : /usr/lib/libjpeg.so Then, I get in the output of ./configure : checking whether to include GD support... yes (static) checking for gdImageString16 in -lgd... yes checking for compress in -lz... yes checking for png_info_init in -lpng... yes checking for gdImageColorResolve in -lgd... yes checking for gdImageCreateFromPng in -lgd... yes checking for gdImageCreateFromGif in -lgd... no checking for libjpeg (needed by gd-1.8+)... yes checking for jpeg_read_header in -ljpeg... yes checking for gdImageCreateFromJpeg in -lgd... yes You can also check php_config.h for the following : #define HAVE_GD_JPG 1 7) Build PHP $make You can check for JPEG support with : $nm ext/gd/gd.o | grep Jpeg U gdImageCreateFromJpeg U gdImageJpeg 8) Install PHP $su #make install #exit 9) That's it ! (don't forget to restart apache, if that's your situation). 10) Test : <?php Header("Content-type: image/jpeg"); $me=ImageCreateFromJPEG("me.jpg"); ImageJPEG($me); ?> Enjoy ! :-) Please check the "optionnal" tests if anything goes wrong.
