3 INSTALLATION ON THE DOS PLATFORM WITH DJGPP
4 -------------------------------------------
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.
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).
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".
28 To compile OpenSSL, start your BASH shell, then configure for DJGPP by
29 running "./Configure" with appropriate arguments:
31 ./Configure no-threads --prefix=/dev/env/DJDIR DJGPP
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.

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."
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".
