Linux下安装PHP的GD支持库
1、安装 zlib
wget ftp://ftp.sunfreeware.com/pub/freeware/SOURCES/zlib-1.2.3.tar.gz
tar -zxf zlib-1.2.3.tar.gz
cd zlib-1.2.3
./configure –prefix=/usr/local/zlib
make
make install
2、安装 jpeg
wget ftp://ftp.sunfreeware.com/pub/freeware/SOURCES/jpeg-6b.tar.gz
mkdir -p /usr/local/jpeg6
mkdir -p /usr/local/jpeg6/bin
mkdir -p /usr/local/jpeg6/lib
mkdir -p /usr/local/jpeg6/include
mkdir -p /usr/local/jpeg6/man
mkdir -p /usr/local/jpeg6/man1
mkdir -p /usr/local/jpeg6/man/man1
tar -zxf jpeg-6b.tar.gz
cd jpeg-6b
./configure –prefix=/usr/local/jpeg6 –enable-shared –enable-static
make
make install
安装完成提示：
Libraries have been installed in:
/usr/local/jpeg6/lib
3、安装 libpng
wget ftp://ftp.sunfreeware.com/pub/freeware/SOURCES/libpng-1.2.16.tar.gz
tar -zxf libpng-1.2.16.tar.gz
cd libpng-1.2.16
./configure –prefix=/usr/local/libpng
make
make install
4、安装 freetype
wget http://download.savannah.nongnu.org/releases/freetype/freetype-2.3.4.tar.gz
tar -zxf freetype-2.3.4.tar.gz
cd freetype-2.3.4
mkdir -p /usr/local/freetype
./configure –prefix=/usr/local/freetype
make
make install
5、安装 GD
wget ftp://ftp.sunfreeware.com/pub/freeware/SOURCES/gd-2.0.33.tar.gz
tar -zxf gd-2.0.33.tar.gz
cd gd-2.0.33
mkdir -p /usr/local/gd2
./configure –prefix=/usr/local/gd2 –with-jpeg=/usr/local/jpeg6/ –with-png=/usr/local/lib/ –with-zlib=/usr/local/lib/ –with-freetype=/usr/local/freetype/
make
make install
--------------------
安装jpg时候，如果出错。
先装libtool
libtool-1.X.tar.gz //是我下载的版本
./configure
make
make install
再装jpegsrc.v6b.tar.gz
./configure --enable-shared --enable-static 这些lib这种包用默认路径就行。不然如果其他的需要这个包还得指它的路径
这里可能会出错
checking host system type… Invalid configuration `x86_64-unknown-linux-gnu ‘: machine `x86_64-unknown ‘ not recognized
checking build system type… Invalid configuration `x86_64-unknown-linux-gnu ‘: machine `x86_64-unknown ‘ not recognized
configure: error: libtool configure failed
或者
/libtool --mode=compile gcc -O2 -I. -c ./jcapimin.c
make: ./libtool：命令未找到
make: *** [jcapimin.lo] 错误 127
./libtool --mode=compile gcc -O2 -I. -c ./cjpeg.c
make: ./libtool：命令未找到
make: *** [cjpeg.lo] 错误 127
解决方法
cp /usr/share/libtool/config/config.guess .
cp /usr/share/libtool/config/config.sub .
cp到jpeg的安装文件目录，注意后面的个“.”
make clean
再重新
./configure --prefix=/usr/local/libjpeg/ --enable-shared --enable-static
make
make install
--------------------------------
如果已经安装php，建议通过追加编译安装
进入“[php解压目录]/ext/gd”目录，执行如下命令：
[php安装目录]/bin/phpize
Java代码
./configure --with-php-config=[php安装目录]/bin/php-config --with-jpeg=[jpeg-6b安装目录] --with-png=[libpng安装目录] --with-freetype=[freetype安装目录] --with-gettext=[gettext安装目录] --with-gd=[gd安装目录]
make
make install
安装成功后会在“[php安装目录]/lib/php/extensions/no-debug-non-zts-20060613”目录下生成gd.so文件，
然后cp [php安装目录]/lib/php/extensions/no-debug-non-zts-20060613/gd.so /opt/php/ext
修改php.ini文件加载gd组件，添加extension_dir=/opt/php/ext和extension=gd.so，如果有extension_dir=/opt/php/ext则不需要增加
Java代码
extension_dir=/opt/php/ext
extension=gd.so
