使用 HTTP 客户端主体时，带有 Boost Mac OSX 的 cpp-Netlib 段错误
cpp-Netlib with Boost Mac OSX seg fault when using HTTP Client body
我最近开始学习需要 Boost 的 cpp-netlib，并且在尝试从站点 http://cpp-netlib.org/0.11.2/examples/http/http_client.html 编译其中一个 cpp-netlib 示例时遇到了一些问题 运行。我以前从未使用过 Boost，我想知道在编译我的程序时我应该如何弄清楚 link 的内容？我目前正在使用自制软件作为我的包管理器。我通过 运行ning
安装了 boost
brew install boost --c++11
然后我通过 运行ning
安装了 cpp-netlib
brew install cpp-netlib
我从站点复制并粘贴了代码示例并对请求 URI 进行了硬编码
#include <boost/network/protocol/http/client.hpp>
#include <iostream>
int main()
{
using namespace boost::network;
http::client client;
http::client::request request("http://www.boost.org");
request << header("Connection", "close");
http::client::response response = client.get(request);
std::cout << body(response) << std::endl;
return 0;
}
经过数小时 Google 与室友的搜索，我们找到了我需要的增强库 link，我们还发现 clang++ 正在寻找我的 Mac 上预装在操作系统中的过时的 openssl系统，而不是我通过自制软件安装的新版本。有了这些新知识，我们发现用这个命令编译是可行的
clang++ -g -I /usr/local/Cellar/openssl/1.0.2e/include test.cpp -L /usr/local/Cellar/openssl/1.0.2e/lib -lboost_system-mt -lboost_thread-mt -lcppnetlib-client-connections -lcppnetlib-uri -lcppnetlib-server-parsers -lssl -lcrypto
我现在在 运行 运行程序时遇到分段错误。当我尝试 运行 lldb 调试我的程序时，lldb 以 "bus error: 10" 退出。
我发现当 运行 宁这行代码
时发生段错误
std::cout << body(response) << std::endl;
当我 运行 valgrind 我得到以下输出

非常感谢任何帮助！
我发现要消除分段错误，我需要包含 -std=c++11 使命令编译
clang++ -std=c++11 -I /usr/local/Cellar/openssl/1.0.2e/include test.cpp -L /usr/local/Cellar/openssl/1.0.2e/lib -lboost_system -lboost_thread-mt -pthread -lcppnetlib-client-connections -lcppnetlib-uri -lcppnetlib-server-parsers -lssl -lcrypto
我应该创建一个 make 文件。
