CPP-入Netlib使用HTTP客户端时身体提升的Mac OSX赛格故障 [英] cpp-Netlib with Boost Mac OSX seg fault when using HTTP Client body
问题描述
最近，我开始学习CPP-NETLIB需要升压并试图编译的CPP-NETLIB的例子之一，从有网站的 http://cpp-netlib.org/0.11.2/examples/http/http_client.html 。我从来没有使用升压，我想知道我应该怎么去搞清楚我的编译程序的时候什么联系呢？我使用自制作为我包管理器当前。我通过运行安装提振
I recently started learning cpp-netlib which requires Boost and am running into some issues when trying to compile one of the cpp-netlib examples from there site http://cpp-netlib.org/0.11.2/examples/http/http_client.html. I have never used Boost before and am wondering how I should go about figuring out what to link when compiling my program? I am using homebrew as my package manager currently. I installed boost by running
brew install boost --c++11
我然后通过运行安装CPP-NETLIB
I then installed cpp-netlib by running
brew install cpp-netlib
我复制并从网站和硬codeD粘贴code例如请求URI
I copied and pasted the code example from the site and hardcoded the request URI
#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;
}
在谷歌的时间与我的室友搜索，我们发现了什么刺激，我需要链接库，我们也发现，铛++是找到我的Mac电脑的老过时的OpenSSL是在pinstalled到操作系统$ P $，而不是新版本我已通过自制软件安装。有了这个新的知识，我们发现，使用这个命令的作品编译
After hours of Google searches with my roommate we found what boost libraries I needed to link, we also found that clang++ was finding my Macs old outdated openssl that is preinstalled in to the operating system and not the new version that I had installed through homebrew. With this new knowledge we found that compiling with this command works
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
运行程序时我现在得到一个分段错误。当我尝试运行LLDB调试我的程序LLDB与退出总线错误：10。
我发现，赛格故障发生在运行此行code时
I am now getting a segmentation fault when running the program. When I attempt to run lldb to debug my program lldb exits with a "bus error: 10". I found that the seg fault is occurring when running this line of code
std::cout << body(response) << std::endl;
当我跑Valgrind的，我得到以下输出
When I run valgrind I get the following output

任何帮助很多AP preciated！
Any help is much appreciated!
推荐答案
我发现，摆脱了段错误的，我需要包括-std = C ++ 11使得命令编译
I found that to get rid of the segmentation fault I needed to include -std=c++11 making the command to compile
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
我也许应该创建一个make文件。
I should probably create a make file.
