我正在尝试从http://www.boost.org/doc/libs/1_47_0/doc/html/boost_asio/example/ssl/client.cpp编译boost示例。出于某种原因，我遇到以下错误，我不知道如何修复它们：
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)’:

我目前正在使用以下行进行编译：
g++ -I /usr/include/boost -Wall -o main ssl_client.cpp -lboost_system
我最近安装了boost：
sudo apt-get install libboost-all-dev
我确信有一个简单的解决办法，有人知道我做错了吗？
=============================================== ========================= 更新：
我现在尝试编译：
g++ -I /usr/include/boost -Wall -o main ssl_client.cpp -lboost_system -lcrypto -lssl -lpthread
但我仍然遇到以下错误：
ssl_client.cpp:37:25: error: ‘boost::asio::ssl::verify_context’ has not been declared

修正了它！这是因为apt-get给了我升级版本1.46，我需要版本1.48。我做了以下修复：
apt-get purge libboost-all-dev
和
apt-get install libboost1.48-all-dev
