CentOS单独编译安装PHP gd库扩展

注意:如果您已经编译安装过GD库,请重新编译安装php不带gd库成功后,执行以下操作

安装libpng

wget http://jaist.dl.sourceforge.net/project/libpng/libpng16/1.6.29/libpng-1.6.29.tar.gz 
tar -xf libpng-1.6.29.tar.gz

cd libpng-1.6.29

CFLAGS="-O3 -fPIC" ./configure --prefix=/usr/local/libpng

make && make install

安装jpegsrc

wget http://www.ijg.org/files/jpegsrc.v9a.tar.gz 
tar -xf jpegsrc.v9a.tar.gz

cd jpeg-9a/

CFLAGS="-O3 -fPIC" ./configure --prefix=/usr/local/jpeg

make && make install

mkdir -p /usr/local/jpeg/include
mkdir -p /usr/local/jpeg/lib
mkdir -p /usr/local/jpeg/bin
mkdir -p /usr/local/jpeg/man/man1

安装freetype

wget http://ftp.twaren.net/Unix/NonGNU/freetype/freetype-2.5.5.tar.gz 
tar -xf freetype-2.5.5.tar.gz

cd freetype-2.5.5

./configure --prefix=/usr/local/freetype

make && make install

跳转到php源码GD目录

cd home/apps/web/php/php-5.6.2/ext/gd

/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config  --with-jpeg-dir=/usr/local/jpeg/  --with-png-dir=/usr/local/libpng/   --with-freetype-dir=/usr/local/freetype/

make

make install

configure: WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers. 请安装re2c

这里出现了错误 Module 'gd' already loaded in Unknown on line 0 原因是编译安装的时候已经带上GD库,请重新编译安装不带上gd

php.ini 添加extension=gd.so

重启web服务器和php-fpm
