| 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. | |
| 451dc18f RL |
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 | ||

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/". | |

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". | |

27 | To compile OpenSSL, start your BASH shell, then configure for DJGPP by |
| 28 | running "./Configure" with appropriate arguments: | |
| 451dc18f | 29 | |
| 9222bc6b AP |
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 | ||
| 9222bc6b AP |
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". |
