Centos 6.2安装libpng错误信息configure: error: ZLib not installed
在编译libpng-1.5.8.tar.gz的时候报错，configure: error: ZLib not installed，我是使用的以下包进行编译的
zlib-1.2.6.tar.gz libpng-1.5.8.tar.gz
解决方法：
1.进入zlib-1.2.6的源文件目录，执行命令 make clean，清除zlib；
2.重新配置 ./configure，后面不要接--prefix参数；
3.编译make && 安装 make install；
4.进入libpng-1.5.8目录，执行命令 ./configure --prefix=/usr/local/libpng;
5.编译make && 安装 make install；
6.安装成功；
