Hello,
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
%28x86%29\boost\boost_1_47;C:\openssl\include\;C:\OpenSSL-Win32\lib;%(AdditionalIncludeDirectories)
Project->General Properties->Linker->Additional Library
Directories: C:\Program Files
%28x86%29\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
#include
#include
int _tmain(int argc, _TCHAR* argv[])
{
return 0;
}
Thanks in advance.
