在centos7 系统编译tengine 时报错：

cc1: all warnings being treated as errors

原因很明显，应该是没有添加编译参数，警告被当成了错误处理。

解决办法;

### \-Wformat=0 就没问题了。Wformat这个配置在Centos下默认是关闭的，所以一直没报错，如果编译的时候打开，也会提示一样的错误。 ###

记录一下另外一个错误：

如果在linux下安装openssl，执行config和make之后，在执行make install时如果出现下面的错误

cms.pod around line 457: Expected text after =item, not a number   
cms.pod around line 461: Expected text after =item, not a number   
cms.pod around line 465: Expected text after =item, not a number   
cms.pod around line 470: Expected text after =item, not a number   
cms.pod around line 474: Expected text after =item, not a number   
POD document had syntax errors at /usr/bin/pod2man line 69.

### 有人验证 安装perl 5.16 可以兼容，安排低版本perl 5.16可以解决问题。 ###

### 解决：   则在root权限下，执行rm -f /usr/bin/pod2man  然后重新make install ###
