How to use cpp-netlib with Visual Studio 2010?

Question

I'm trying to use cpp-netlib with Visual Studio 2010. I've built cpp-netlib and add .lib files to my project, but I can't compile them.

--Environment

• Windows 7 x64
• cpp-netlib 0.11.0
• boost 1.55.0
• Win32 OpenSSL v1.0.1f

My code is here.

#include <boost/network/protocol/http/client.hpp>
#include <iostream>

int main(int argc, char *argv[]) {
    using namespace boost::network;

    if (argc != 2) {
        std::cout << "Usage: " << argv[0] << " [url]" << std::endl;
        return 1;
    }

    http::client client;
    http::client::request request(argv[1]);
    request << header("Connection", "close");
    http::client::response response = client.get(request);
    std::cout << body(response) << std::endl;

    return 0;
}

I added the cpp-netlib library path and the cpp-netlib include path to the project. Boost and openssl paths were also added. I added the libs to the project.

• libboost_system-vc100-mt-gd-1_55.lib
• libboost_date_time-vc100-mt-gd-1_55.lib
• libboost_regex-vc100-mt-gd-1_55.lib
• cppnetlib-client-connections.lib
• cppnetlib-uri.lib

I think the errors come from something related OpenSSL.

Error   55  error LNK2019: unresolved external symbol - function _BIO_ctrl ...

Actually, I have Japanese one so it's like below.

エラー 55  error LNK2019: 未解決の外部シンボル _BIO_ctrl が関数 "public: class boost::system::error_code const & __thiscall boost::asio::ssl::detail::engine::map_error_code(class boost::system::error_code &)const " (?map_error_code@engine@detail@ssl@asio@boost@@QBEABVerror_code@system@5@AAV675@@Z) で参照されました。    cppnetlib-client-connections.lib(client.obj)

Could you tell me what I'm missing? I tried to add more libs to the project, but it still didn't work.

Answer 1

I should've got to add these two library.

libeay32.lib ssleay32.lib

Answer 2

我遇到了同样的问题，除了我通过使用SSL的WIN32版本而不是X64版本解决了它。
