   3  INSTALLATION ON THE DOS PLATFORM WITH DJGPP
   4  -------------------------------------------
   5
   6  OpenSSL has been ported to DJGPP, a 32-bit run-time environment for
   7  16-bit DOS, but only with long filename support. If you wish to
   8  compile on native DOS with 8+3 filenames, you will have to tweak the
   9  installation yourself, including renaming files with illegal
  10  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, such
  17  as "ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp". You also need to
  18  have the WATT-32 networking package installed before you try to compile
  19  openssl. This can be obtained from "http://www.bgnett.no/~giva/".
  20  The Makefile assumes that the WATT-32 code is in the directory
  21  specified by the environment variable WATT_ROOT. If you have watt-32
  22  in directory "watt32" under your main DJGPP directory, specify
  23  WATT_ROOT="/dev/env/DJDIR/watt32".
  24
  25  To compile openssl, start your BASH shell. Then configure for DOS by
  26  running "./Configure" with appropriate arguments. The basic syntax for
  27  DOS is:
  28  ./Configure no-threads --prefix=/dev/env/DJDIR DJGPP
  29
  30  You may run out of DPMI selectors when running in a DOS box under
  31  Windows. If so, just close the BASH shell, go back to Windows, and
  32  restart BASH. Then run "make" again.
  33
  34  Building openssl under DJGPP has been tested with DJGPP 2.03,
  35  GCC 2.952, GCC 2.953, perl 5.005_02 and perl 5.006_01.

  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 OpenSSL checks upon /dev/urandom$ for a 3rd party DOS
  47  driver. One such driver implemented by Robert Rothenberg "Walking-Owl"
  48  can be obtained from "http://www.funet.fi/pub/crypt/random/noise063.zip."
