Boost SSL with Visual Studio 2010 and OpenSSL - visual-studio-2010

Question

I'm trying to compile the Boost 1.47 ASIO SSL server and client examples. I can sucessfully incorporate Boost into my project, but I cannot incorporate OpenSSL. When I try to add it I get the errors:

I have tried adding the directory C:\OpenSSL-Win32\lib\, C:\OpenSSL-Win32\lib\VC\, C:\OpenSSL-Win32\lib\VC\static, C:\OpenSSL-Win32\bin, C:\OpenSSL-Win32\include to Project->General Properties->Linker->Additional Library Directories using the openssl pre-compiled libraries (http://www.openssl.org/related/binaries.html). I have also tried compiling OpenSSL myself with the same errors. I'm really at a loss, I have tried everything I have searched Google about a thousand times, tried IRC, every combination of directories I can think of...
My setup is:
Windows 7 64-bit
Windows Visual Studio 2010 64 bit
Boost 1.47
OpenSSL 1.0.0E and G
C/C++ Additional Include Directories: C:\Program Files (x86)\boost\boost_1_47;C:\openssl\include\;C:\OpenSSL-Win32\lib;%(AdditionalIncludeDirectories)
Project->General Properties->Linker->Additional Library Directories: C:\Program Files (x86)\boost\boost_1_47\lib;C:\openssl\lib;C:\openssl;%(AdditionalLibraryDirectories)
- I've tried adding every directory to this property as well....
Right now I'm just trying to compile the following in a VS C++ console project:
// SSLServer.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <cstdlib>
#include <iostream>
#include <boost/bind.hpp>
#include <boost/asio.hpp>
#include <boost/asio/ssl.hpp>
int _tmain(int argc, _TCHAR* argv[])
{
return 0;
}
Thanks in advance.

Answer 1

Looks like you're using the 32-bit version of OpenSSL on a 64-bit machine.
Try downloading the 64-bit version (Win64 OpenSSL v1.0.0g) from http://www.slproweb.com/products/Win32OpenSSL.html
After that's installed (if you use default paths), you should have a C:\OpenSSL-Win64 folder.
You should add:
C:\OpenSSL-Win64\include to your Additional Include Directories
C:\OpenSSL-Win64\lib\VC\static or C:\OpenSSL-Win64\lib\VC to your Additional Library Directories depending on whether you want the static libs or the dlls respectively
libeay32<XXX>.lib and ssleay32<XXX>.lib to Additional Dependencies where <XXX> matches whatever setting you have for [C/C++]->[Code Generation]->[Runtime Library]

Answer 2

I managed to get your little program above to build by linking with the 32-bit version of the Boost library along with the 32-bit version of OpenSSL. You will also need the 32-bit version of the redistributables as well. The bug is present in Boost version 1.51 and 1.52, which are the only versions I tested.
I believe there is a bug in the 64-bit version of the ASIO library. Although, it is possible that it is some sort of configuration problem that has affected many others. I have submitted a Boost bug report about the issue.

Answer 3

I met with the similar issue(VS2010)， solved methods:
1)Properties->C/C++ ->general->additional include Directories: yourpath\boost_1_58_0\boost_1_58_0 (I use 1.58.0 version)
2)Properties->Linker ->general->additional library directories:
yourpath\boost_1_58_0\boost_1_58_0\stage\lib
3)Properties->Linker ->Input ->additional Dependencies:
libeay32.lib
ssleay32.lib
These two .lib files are copied from openssl install directory.
