Building OpenSSL for Windows

Install Dependencies


  • Extract OpenSSL source and navigate to it in VC++ prompt.
  • In Visual C++ 2008 32-bit Command Prompt:
    set PATH=C:\Users\IEUser\AppData\Local\nasm;%PATH%
    perl Configure VC-WIN32 --prefix=C:\OpenSSL-Win32
    nmake -f ms\ntdll.mak
    nmake -f ms\ntdll.mak test
    nmake -f ms\ntdll.mak install


There are precompiled but need to ensure the compiler is msvc 9.0 (2008) along with the openssl include and lib folders for libtorrent to link to.
