centos 7源码安装mplayer播放器出错，帮忙看报错信息

shizongger

按照本教程http://blog.csdn.net/u010048823/article/details/51292544来作的实验，在./config这一步中失败了，报错信息如下：

然后我打开了config.log查看报错信息，如下：

1. [root@shizongger MPlayer-1.3.0]# cat config.log

我知道报错信息很长，但是还是劳烦大神帮忙看看是怎么回事儿！

yasm没装啊，另外如果你是打算练习一下源码安装，建议别用mplayer试手，这个程序依赖的东西很多很杂，不是适合新手入门

yasm没装。报错就按错误找。这是Linux的基本能力呀！
