The program fails to build when linking with the 64 bit version of the Boost library as well as the 64 bit version of the OpenSSL library. The build succeeds when the 32 bit version of the Boost library is used in conjunction with the 32 bit version of the OpenSSL library. I have tried building it for Boost versions 1.51 and 1.52. Have also tried the c and j versions of the 64 bit OpenSSL library for Windows which results in the same error. The link above is for building with VS2010. The same error results for me when I try to build with VS2008. I have also written a description of the problem in StackOverflow.com as well which involved building one of the ASIO example programs: http://stackoverflow.com/questions/14286346/link-unresolved-error-with-vs2008-boost-asio-and-openssl The work around to the problem right now is to build it with 32 bit libraries. If you can successfully build using VS2010 or VS2008 with the 64 bit versions, then please advise on what you think the problem might be. This problem has been reported by several individuals."
