1 | Notes for the DOS platform with DJGPP |
| 2 | ===================================== | |
| 451dc18f | 3 | |
| 9222bc6b AP |
4 | OpenSSL has been ported to DJGPP, a Unix look-alike 32-bit run-time |
| 5 | environment for 16-bit DOS, but only with long filename support. | |
| 6 | If you wish to compile on native DOS with 8+3 filenames, you will | |
| 7 | have to tweak the installation yourself, including renaming files | |
| 8 | with illegal or duplicate names. | |
| 451dc18f RL |
9 | |
| 10 | You should have a full DJGPP environment installed, including the | |
| 11 | latest versions of DJGPP, GCC, BINUTILS, BASH, etc. This package | |
| 1dc1ea18 | 12 | requires that PERL and the PERL module `Text::Template` also be |
| 9f1fe6a9 | 13 | installed (see [NOTES-PERL.md](NOTES-PERL.md)). |
| 451dc18f | 14 | |
| 9222bc6b | 15 | All of these can be obtained from the usual DJGPP mirror sites or |
| 1dc1ea18 | 16 | directly at <http://www.delorie.com/pub/djgpp>. For help on which |
| 9222bc6b | 17 | files to download, see the DJGPP "ZIP PICKER" page at |
| 1dc1ea18 | 18 | <http://www.delorie.com/djgpp/zip-picker.html>. You also need to have |
| 9222bc6b | 19 | the WATT-32 networking package installed before you try to compile |
| 1dc1ea18 | 20 | OpenSSL. This can be obtained from <http://www.watt-32.net/>. |
| 5319be44 RL |
21 | The Makefile assumes that the WATT-32 code is in the directory |
| 22 | specified by the environment variable WATT_ROOT. If you have watt-32 | |
| 1dc1ea18 DDO |
23 | in directory `watt32` under your main DJGPP directory, specify |
| 24 | `WATT_ROOT="/dev/env/DJDIR/watt32"`. | |
| 451dc18f | 25 | |
| 9222bc6b | 26 | To compile OpenSSL, start your BASH shell, then configure for DJGPP by |
| 1dc1ea18 | 27 | running `./Configure` with appropriate arguments: |
| 451dc18f | 28 | |
| 1dc1ea18 | 29 | ./Configure no-threads --prefix=/dev/env/DJDIR DJGPP |
| df443918 | 30 | |
| 1dc1ea18 | 31 | And finally fire up `make`. You may run out of DPMI selectors when |
| 9222bc6b | 32 | running in a DOS box under Windows. If so, just close the BASH |
| 1dc1ea18 | 33 | shell, go back to Windows, and restart BASH. Then run `make` again. |

| 38 | Quoting FAQ: | |
| 39 | ||
| 40 | "Cryptographic software needs a source of unpredictable data to work | |
| 41 | correctly. Many open source operating systems provide a "randomness | |
| 1dc1ea18 | 42 | device" (`/dev/urandom` or `/dev/random`) that serves this purpose." |
| 0b52f89b | 43 | |
| 1dc1ea18 DDO |
44 | As of version 0.9.7f DJGPP port checks upon `/dev/urandom$` for a 3rd |
| 45 | party "randomness" DOS driver. One such driver, `NOISE.SYS`, can be | |
| 46 | obtained from <http://www.rahul.net/dkaufman/index.html>. |
