我在编译http://www.boost.org/doc/libs/1_47_0/doc/html/boost_asio/example/ssl/client.cpp的boost示例。出于某种原因，我得到了下面的错误，我不知道如何解决这些问题：错误编译ssl客户端的boost示例
ssl_client.cpp:37:25: error: ‘boost::asio::ssl::verify_context’ has not been declared
ssl_client.cpp: In constructor ‘client::client(boost::asio::io_service&, boost::asio::ssl::context&, boost::asio::ip::basic_resolver<boost::asio::ip::tcp>::iterator)’:

ssl_client.cpp:31:5: error: ‘async_connect’ is not a member of ‘boost::asio’

我目前使用以下行编译：
g++ -I /usr/include/boost -Wall -o main ssl_client.cpp -lboost_system
而且我最近安装升压通过：
sudo apt-get install libboost-all-dev
我敢肯定有一个简单的修复，有没有人知道我做错了什么？
============================================== ========================== 更新：
现在我已经试过编译：
g++ -I /usr/include/boost -Wall -o main ssl_client.cpp -lboost_system -lcrypto -lssl -lpthread
，但我仍然收到以下错误：
ssl_client.cpp:37:25: error: ‘boost::asio::ssl::verify_context’ has not been declared

看到了这一点？ http://stackoverflow.com/a/29118744/85371 – sehe
刚刚尝试过它，使用-lcrypto，-lssl和-lpthread，但由于某些原因我仍然收到大量错误。 –
