我已经安装了Asterisk 11.9.0，但是当我尝试启动Asterisk实例时，我得到这个错误:
[root@localhost]# asterisk -rvvvv
asterisk: symbol lookup error: /usr/lib/libasteriskssl.so.1: undefined symbol: _ast_mem_backtrace_buffer
我试着在网上搜索，但是找不到这个错误的任何解释。如果有人在这方面指导我，我将非常感激，我正在使用Centos 6。x:2.6.32-358.el6.x86_64

期待您的反馈。由于
您已经删除了所有的libssl副本，如果有的话
之后需要安装libssl-devel并重新编译asterisk与您的库版本。
