    3:  INSTALLATION ON THE DOS PLATFORM WITH DJGPP
    4:  -------------------------------------------
    5: 
    6:  OpenSSL has been ported to DJGPP, a Unix look-alike 32-bit run-time
    7:  environment for 16-bit DOS, but only with long filename support.
    8:  If you wish to compile on native DOS with 8+3 filenames, you will
    9:  have to tweak the installation yourself, including renaming files
   10:  with illegal or duplicate names.
   11: 
   12:  You should have a full DJGPP environment installed, including the
   13:  latest versions of DJGPP, GCC, BINUTILS, BASH, etc. This package
   14:  requires that PERL and BC also be installed.
   15: 
   16:  All of these can be obtained from the usual DJGPP mirror sites or
   17:  directly at "http://www.delorie.com/pub/djgpp". For help on which
   18:  files to download, see the DJGPP "ZIP PICKER" page at
   19:  "http://www.delorie.com/djgpp/zip-picker.html". You also need to have
   20:  the WATT-32 networking package installed before you try to compile
   21:  OpenSSL. This can be obtained from "http://www.bgnett.no/~giva/".
   22:  The Makefile assumes that the WATT-32 code is in the directory
   23:  specified by the environment variable WATT_ROOT. If you have watt-32
   24:  in directory "watt32" under your main DJGPP directory, specify
   25:  WATT_ROOT="/dev/env/DJDIR/watt32".
   26: 
   27:  To compile OpenSSL, start your BASH shell, then configure for DJGPP by
   28:  running "./Configure" with appropriate arguments:
   29: 
   30:         ./Configure no-threads --prefix=/dev/env/DJDIR DJGPP
   31:  
   32:  And finally fire up "make". You may run out of DPMI selectors when
   33:  running in a DOS box under Windows. If so, just close the BASH
   34:  shell, go back to Windows, and restart BASH. Then run "make" again.

   39:  Quoting FAQ:
   40: 
   41:   "Cryptographic software needs a source of unpredictable data to work
   42:    correctly.  Many open source operating systems provide a "randomness
   43:    device" (/dev/urandom or /dev/random) that serves this purpose."
   44: 
   45:  As of version 0.9.7f DJGPP port checks upon /dev/urandom$ for a 3rd
   46:  party "randomness" DOS driver. One such driver, NOISE.SYS, can be
   47:  obtained from "http://www.rahul.net/dkaufman/index.html".
