#### 解决方法

autoconf版本太高造成的,我的办法是安装autoconf 2.13
redhat类系统运行如下命令
yum install autoconf213.noarch
export PHP_AUTOCONF=/usr/bin/autoconf-2.13
export PHP_AUTOHEADER=/usr/bin/autoheader-2.13

64位环境下
configure: error: libjpeg.(a|so) not found.
或者 configure: error: *.(a|so) not found.
这些库已经安装了但还报错
在configure 时加参数 –with-libdir=lib64
```
