fatal error: openssl/bio.h

admin

出现这个或者fatal error: openssl/名单.h: No such file or directory。都是没有安装libssl-dev～

libssl-dev包含libraries, header files and manpages，他是openssl的一部分，而openssl对ssl进行了实现～

解决方案：

1. 使用sudo apt-get install libssl-dev来安装libssl-dev即可

解决方案：

1. sudo apt-get install aptitude
   
2. 
   
3. sudo aptitude install libssl-dev
   
4. 
   
5. dpkg -l *libssl*

执行sudo aptitude install libssl-dev前，可以先查看下工具安装情况，我的安装情况如下：
