Compiling OpenSSL for Win x64

I’m upgrading the components of the user provisioning system I built. Previously, I used ActiveState Perl and the UWinnipeg PPM repository to get the Net::LDAPS stack working.

This time, though, I decided I wanted to use the native architecture of my Server 2008 R2 systems. I am using the Perl64 install from ActiveState, but I have to build my own SSL libraries (and maybe roll up PPMs for the needed perl mods).

I just compiled OpenSSL for x64 (amd64), mostly following the instructions in the INSTALL.W64 and INSTALL.W32 documents. I’m blogging the step for my future reference:

1. Open a VS x64 Win64 Command Prompt and navigate to the source directory
2. perl Configure VC-WIN64A –prefix=c:\local\openssl
3. ms\do_win64a.bat
4. nmake -f ms\ntdll.mak
5. nmake -f ms\ntdll.mak test (all tests passed)
6. nmake -f ms\ntdll.mak install

Running the openssl command succeeds:

C:\local\openssl\bin>openssl version
