| 3 | INSTALLATION ON THE DOS PLATFORM WITH DJGPP |
| 4 | ------------------------------------------- |

| Andy Polyakov | 9222bc6 | 2005-01-14 16:25:36 +0000 | [diff] [blame] | 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. |
| Richard Levitte | 451dc18 | 2002-06-13 20:42:35 +0000 | [diff] [blame] | 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 BC also be installed. |
| 15 | |
| Andy Polyakov | 9222bc6 | 2005-01-14 16:25:36 +0000 | [diff] [blame] | 16 | All of these can be obtained from the usual DJGPP mirror sites or |
| 17 | directly at "http://www.delorie.com/pub/djgpp". For help on which |
| 18 | files to download, see the DJGPP "ZIP PICKER" page at |
| 19 | "http://www.delorie.com/djgpp/zip-picker.html". You also need to have |
| 20 | the WATT-32 networking package installed before you try to compile |
| 21 | OpenSSL. This can be obtained from "http://www.bgnett.no/~giva/". |
| Richard Levitte | 5319be4 | 2002-12-04 09:54:10 +0000 | [diff] [blame] | 22 | The Makefile assumes that the WATT-32 code is in the directory |
| 23 | specified by the environment variable WATT_ROOT. If you have watt-32 |
| 24 | in directory "watt32" under your main DJGPP directory, specify |
| 25 | WATT_ROOT="/dev/env/DJDIR/watt32". |

| Andy Polyakov | 9222bc6 | 2005-01-14 16:25:36 +0000 | [diff] [blame] | 27 | To compile OpenSSL, start your BASH shell, then configure for DJGPP by |
| 28 | running "./Configure" with appropriate arguments: |
| Richard Levitte | 451dc18 | 2002-06-13 20:42:35 +0000 | [diff] [blame] | 29 | |
| Andy Polyakov | 9222bc6 | 2005-01-14 16:25:36 +0000 | [diff] [blame] | 30 | ./Configure no-threads --prefix=/dev/env/DJDIR DJGPP |
| 31 | |
| 32 | And finally fire up "make". You may run out of DPMI selectors when |
| 33 | running in a DOS box under Windows. If so, just close the BASH |
| 34 | shell, go back to Windows, and restart BASH. Then run "make" again. |

| 39 | Quoting FAQ: |
| 40 | |
| 41 | "Cryptographic software needs a source of unpredictable data to work |
| 42 | correctly. Many open source operating systems provide a "randomness |
| 43 | device" (/dev/urandom or /dev/random) that serves this purpose." |
| 44 | |
| Andy Polyakov | 9222bc6 | 2005-01-14 16:25:36 +0000 | [diff] [blame] | 45 | As of version 0.9.7f DJGPP port checks upon /dev/urandom$ for a 3rd |
| 46 | party "randomness" DOS driver. One such driver, NOISE.SYS, can be |
| 47 | obtained from "http://www.rahul.net/dkaufman/index.html". |
