| 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. | |

| 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". |
