PHP 最全编译安装 gd 库

安装gd依赖库

　　freetype

wget http://download.savannah.gnu.org/releases/freetype/freetype-2.4.0.tar.gz

tar jxvf freetype-2.4.0.tar.gz

cd freetype-2.4.0

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

make && make install

　jpegsrc

wget http://www.ijg.org/files/jpegsrc.v9.tar.gz

tar -zxvf jpegsrc.v9.tar.gz

cd jpeg-9

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

make && make install

libpng

wget http://jaist.dl.sourceforge.net/project/libpng/libpng12/1.2.56/libpng-1.2.56.tar.gz 

tar -zxvf libpng-1.2.56.tar.gz

cd libpng-1.2.56
 
./configure --prefix=/usr/local/libpng
 
make && make install

安装 gd 库

cd /path/php-5.6.25

cd 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

其中with-php-config 为PHP相关目录   with-jpeg-dir  with-png-dir    with-freetype 分别与上面的configure 指定的prefix 安装路径保持一致
