How to use cpp-netlib with Visual Studio 2010? - c++

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.

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

I ran into the same problem, except i fixed it by using the WIN32 version of SSL instead of the X64 version.
