编译安装libjpeg

由于libjpeg自带的ltconfig脚本有问题，所以需要手工从系统里面拷贝一份覆盖

tar zxvf jpegsrc.v6b.tar.gz

cd jpeg-6b

cp /usr/share/libtool/config.* .

./configure –host=Darwin –enable-shared

make

make install

编译安装libpng

tar jxvf libpng-1.2.25.tar.bz2

cd libpng-1.2.25

./configure

make

make install

编译安装freetype

tar zxvf freetype-2.3.5.tar.gz

cd freetype-2.3.5

./configure

make

make install

重新编译PHP，只需要./configure的时候加上以下参数

–with-gd –with-jpeg-dir –with-png-dir –with-zlib-dir –with-freetype-dir –enable-gd-native-ttf

观察configure的log，如果有下面的输出就表示成功了。

checking for GD support… yes

checking for the location of libjpeg… yes

checking for the location of libpng… yes

checking for FreeType 2… yes

编译安装完php后，运行php -m可以看到所包含的模块

如果需要编译为64位的PHP(如core 2 duo的CPU,leopard系统),在configure前先运行下面的命令

export CFLAGS='-arch ppc -arch ppc64 -arch i386 -arch x86_64 -g -O2 -pipe'
export CXXFLAGS="${CFLAGS}"
