| 3 | INSTALLATION ON THE DOS PLATFORM WITH DJGPP
|
---|
| 4 | -------------------------------------------
|
---|
| 5 |
|
---|
| 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.
|
---|
| 11 |
|
---|
| 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).
|
---|
| 16 |
|
---|
| 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".
|
---|
| 27 |
|
---|
| 28 | To compile OpenSSL, start your BASH shell, then configure for DJGPP by
|
---|
| 29 | running "./Configure" with appropriate arguments:
|
---|
| 30 |
|
---|
| 31 | ./Configure no-threads --prefix=/dev/env/DJDIR DJGPP
|
---|
| 32 |
|
---|
| 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.

| 40 | Quoting FAQ:
|
---|
| 41 |
|
---|
| 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."
|
---|
| 45 |
|
---|
| 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".
