安装GD库

所需的源码包及下载:

gd-2.0.33.tar.gz http://www.boutell.com/gd/
jpegsrc.v6b.tar.gz http://www.ijg.org/
libpng-1.2.7.tar.tar http://sourceforge.net/projects/libpng/
zlib-1.2.2.tar.gz http://sourceforge.net/projects/zlib/
freetype-2.1.9.tar.gz http://sourceforge.net/projects/freetype/

安装步骤：

先安装zlib,freetype,libpng,jpeg,再装GD

1.装zlib

tar zxvf zlib-1.2.2.tar.gz
cd zlib-1.2.2
./configure
make
make install

2.安装libpng

tar zxvf libpng-1.2.7.tar.tar
cd libpng-1.2.7
cd scripts/
mv makefile.linux ../makefile
cd ..
make
make install
注意，这里的makefile不是用./configure生成，而是直接从scripts/里拷一个

3.安装freetype

tar zxvf freetype-2.1.9.tar.gz
cd freetype-2.1.9
./configure
make
make install

4.安装Jpeg

tar zxvf jpegsrc.v6b.tar.gz
cd jpeg-6b/
./configure –enable-shared
make
make test
make install
注意，这里configure一定要带–enable-shared参数，不然，不会生成共享库

5.安装GD

tar zxvf gd-2.0.33.tar.gz
cd gd-2.0.33
./configure –with-png –with-freetype –with-jpeg
make install
