Question

美好的一天！我目前正在开发大型p2p通信服务，而且我使用的是mongoose网络服务器，我已经开始使用SSL，为了发送数据，我想我可以使用Boost中的asio。事情是我在编译时遇到错误，实际上是多个错误。

In function `boost::asio::ssl::context::context(boost::asio::ssl::context_base::method)':

我的代码：

#include <iostream>
#include <fstream>
#include <cstdio>
#include <cstring>
#include <boost/asio.hpp>
#include <boost/asio/ssl.hpp>
#include <boost/version.hpp>

char* process_http(int sockfd, char *host, char *page, char *poststr) {
    //This is to avoid application crash when we perform write() or read.
    signal(SIGPIPE, SIG_IGN);
    ssize_t n;
    int sendlineSize = strlen(page) + MAXLINE + 1;
    char sendline[sendlineSize];
    char *recvline = (char *) malloc(sizeof (char) * (sendlineSize));

    sprintf(sendline, "POST %s HTTP/1.0\r\n"
            "Host: %s\r\n"
            "Content-type: application/x-www-form-urlencoded\r\n"
            "Content-length: %d\r\n\r\n"
            "%s", page, host, (int) strlen(poststr), poststr);

    if (write(sockfd, sendline, sizeof (sendline)) == -1) {
        return NULL;
    }

    while ((n = read(sockfd, recvline, sendlineSize)) != 0) {
        recvline[n] = '\0';
    }

    return recvline; //this must be freed by the receiver!! ( allocated here! )
}

我怀疑代码是问题，我尝试更改标志，这是：

-lpthread -lrt -ldl -lboost_serialization -lboost_system -lboost_filesystem -lboost_thread -ltomcrypt -DLTM_DESC -lcrypto -lcrypt -fno-rtti -lboost_program_options -lboost_thread -lssl -lcrypto -lboost_system

我使用Boost进行序列化和一些文件解析，所以我怀疑升级库有问题，升级库版本是1.64，OpenSSL版本是OpenSSL 1.1.0e 2017年2月16日。我已经验证了所有的图书馆，看起来很好，但我似乎无法找到原因。我也使用Netbeans，我没有使用命令行编译它。该项目相当大，所以我认为链接器在检测相关方法时遇到问题。

提升asio undefined引用TLS_method，TLS_client_method等
