yum编译执行命令如下：

yum install ntpdate wget autoconf automakelibtool gcc-c++ zlib-devel libjpeg-devel sqlite-devel libcurl-devel pcre-develspeex-devel libedit-devel openssl-devel libogg-devel libvorbis-devel

报错信息如下：

解决思路：

1：执行yum clean all 清除缓存目录下的软件包及旧的headers；

2：接着执行 yum list 重新列出所有已经安装和可以安装的软件包；

3：重新执行上述命令，发现yum编译成功；

注意：如果执行 yum list 报错，那就检查一下yum仓库是否有问题；并清除/etc/yum.repos.d/下多余.repo文件！
