Purpose

  This recipe demonstrates how to build a static version of OpenSSL
  using Microsoft Visual Studio 6.

Motivation

  When compiling WebJob, I prefer to link against statically compiled
  OpenSSL libraries.  Since WebJob must be compiled as a multithreaded
  binary on WIN32 platforms, it is necessary to compile against a
  compatible set of OpenSSL libraries -- i.e., the standard OpenSSL
  build won't work.

Requirements

  Cooking with this recipe requires Microsoft Visual Studio 6 and
  Active Perl 5.8.7 or higher. Note: Higher versions of Visual Studio
  have not been tested, so your results may vary.

  This recipe was last tested on openssl-0.9.8b.

Solution

  The solution is to modify nt.mak to use /MT prior to building
  OpenSSL.

  The following steps describe how to implement this solution.

  1. Unpack OpenSSL tar ball.

  2. Open a command window and run:

       cd <path_to_openssl_source>
       VCVARS32.bat
       perl Configure VC-WIN32
       ms\do_ms

  3. Edit ms\nt.mak and replace /MD with /MT in the CFLAG macro.
     This causes OpenSSL to link against multi-threaded libraries.

       notepad ms\nt.mak

  4. Compile with:

       nmake -f ms\nt.mak

  5. Test with:

       cd out32
       ..\ms\test

  6. Install OpenSSL using the script provided in Appendix 1.

       cd ..
       <path_to_script>\install_openssl.cmd
