  3.  INSTALLATION ON THE DOS PLATFORM WITH DJGPP
    4. 

  4.  -------------------------------------------
    5. 

  5. 

  6.  OpenSSL has been ported to DJGPP, a Unix look-alike 32-bit run-time
    7. 

  7.  environment for 16-bit DOS, but only with long filename support.
    8. 

  8.  If you wish to compile on native DOS with 8+3 filenames, you will
    9. 

  9.  have to tweak the installation yourself, including renaming files
    10. 

  10.  with illegal or duplicate names.
    11. 

  11. 

  12.  You should have a full DJGPP environment installed, including the
    13. 

  13.  latest versions of DJGPP, GCC, BINUTILS, BASH, etc. This package
    14. 

  14.  requires that PERL and the PERL module Text::Template also be
    15. 

  15.  installed (see NOTES.PERL).
    16. 

  16. 

  17.  All of these can be obtained from the usual DJGPP mirror sites or
    18. 

  18.  directly at "http://www.delorie.com/pub/djgpp". For help on which
    19. 

  19.  files to download, see the DJGPP "ZIP PICKER" page at
    20. 

  20.  "http://www.delorie.com/djgpp/zip-picker.html". You also need to have
    21. 

  21.  the WATT-32 networking package installed before you try to compile
    22. 

  22.  OpenSSL. This can be obtained from "http://www.watt-32.net/".
    23. 

  23.  The Makefile assumes that the WATT-32 code is in the directory
    24. 

  24.  specified by the environment variable WATT_ROOT. If you have watt-32
    25. 

  25.  in directory "watt32" under your main DJGPP directory, specify
    26. 

  26.  WATT_ROOT="/dev/env/DJDIR/watt32".
    27. 

  27. 

  28.  To compile OpenSSL, start your BASH shell, then configure for DJGPP by
    29. 

  29.  running "./Configure" with appropriate arguments:
    30. 

  30. 

  31. 	./Configure no-threads --prefix=/dev/env/DJDIR DJGPP
    32. 

  32.  
    33. 

  33.  And finally fire up "make". You may run out of DPMI selectors when
    34. 

  34.  running in a DOS box under Windows. If so, just close the BASH
    35. 

  35.  shell, go back to Windows, and restart BASH. Then run "make" again.

  40.  Quoting FAQ:
    41. 

  41. 

  42.   "Cryptographic software needs a source of unpredictable data to work
    43. 

  43.    correctly.  Many open source operating systems provide a "randomness
    44. 

  44.    device" (/dev/urandom or /dev/random) that serves this purpose."
    45. 

  45. 

  46.  As of version 0.9.7f DJGPP port checks upon /dev/urandom$ for a 3rd
    47. 

  47.  party "randomness" DOS driver. One such driver, NOISE.SYS, can be
    48. 

  48.  obtained from "http://www.rahul.net/dkaufman/index.html".
