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

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