+ 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.
+
+ RUN-TIME CAVEAT LECTOR
+ --------------
+
+ 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".
