- 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 BC also be installed.
- 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.bgnett.no/~giva/".
- 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".
