   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 the PERL module Text::Template also be
  15  installed (see NOTES.PERL).
  16
  17  All of these can be obtained from the usual DJGPP mirror sites or
  18  directly at "http://www.delorie.com/pub/djgpp". For help on which
  19  files to download, see the DJGPP "ZIP PICKER" page at
  20  "http://www.delorie.com/djgpp/zip-picker.html". You also need to have
  21  the WATT-32 networking package installed before you try to compile
  22  OpenSSL. This can be obtained from "http://www.watt-32.net/".
  23  The Makefile assumes that the WATT-32 code is in the directory
  24  specified by the environment variable WATT_ROOT. If you have watt-32
  25  in directory "watt32" under your main DJGPP directory, specify
  26  WATT_ROOT="/dev/env/DJDIR/watt32".
  27
  28  To compile OpenSSL, start your BASH shell, then configure for DJGPP by
  29  running "./Configure" with appropriate arguments:
  30
  31         ./Configure no-threads --prefix=/dev/env/DJDIR DJGPP
  32
  33  And finally fire up "make". You may run out of DPMI selectors when
  34  running in a DOS box under Windows. If so, just close the BASH
  35  shell, go back to Windows, and restart BASH. Then run "make" again.

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