Issues building/linking OpenSSL on Win7 64bit and linking in VS2010

[andrewmchugh]

I was running a boost ssl project on linux which OpenSSL seems to be less of a ball ache. Since boost requires openssl to be installed, I tired to install it and then use an SSL example to test the installation.

I 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 prefix so it just builds to /usr/local

ms\do_win64a

// not using the DLLs but I built them anyway.

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

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

It all builds without failing (or doesn't flag anything up) but the project fails to compile due to undefined symbols. I know it must be something with the way I built it. But I can see where I could have gone wrong since is so simple. I have deleted the src and build are tired repeating a few times but had no luck. I am literally pulling my hair out it has brought my project to a standstill.

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
ssleay32.lib


Source file and header is just osslcrypto from an example.

Fixed. Was trying to build a 32bit program with 64 bit libs linked. What I did above was fine.
