boost::asio ssl linking error

I am having issues with undefined symbols. My boost installation is fine as I have used it for other projects. I understand that I need OpenSSL installed, So installed it in the following way.

I then ran the following commands with VS2010 command prompt with the extracted OpenSSL source (most recent from openssl site) as the working directory.

perl Configure VC-WIN64A no-shared no-idea // I don't trust this.

ms\do_win64a

nmake -f ms\ntdll.mak
nmake -f ms\ntdll.mak install

nmake -f ms\nt.mak
nmake -f ms\nt.mak install

The source file is just the boost example. http://www.boost.org/doc/libs/1_52_0/doc/html/boost_asio/example/ssl/client.cpp

My VS2010 project is setup as follows.

C/C++ > General > Addition Include Directories

E:\libraries\boost_1_49_0   //as used in past projects 
E:\usr\local\ssl\include    //just installed

Linker > General > Addition Library Directories

E:\libraries\boost_1_49_0\stage\lib
E:\usr\local\ssl\lib

Linker > Input > Addition Directories

libeay32.lib

I thought that it might must have been boost tripping out. So I tried an SSL crypto example and that had undefined symbols.

OS is Windows 7 64Bit

Answer 1

I was trying to build a 32bit program with the 64 bit libs.

I changed the following from above to build the 64 bit version

perl Configure VC-WIN64A no-asm –prefix=\Dir\for\64\bit\ssl -DUNICODE -D_UNICODE

ms\do_win64a.bat

then nmake as normal
