3 | INSTALLATION ON THE DOS PLATFORM WITH DJGPP | |
4 | ------------------------------------------- | |
5 | ||
6 | Openssl has been ported to DOS, but only with long filename support. If | |
7 | you wish to compile on native DOS with 8+3 filenames, you will have to | |
8 | tweak the installation yourself, including renaming files with illegal | |
9 | or duplicate names. | |
10 | ||
11 | You should have a full DJGPP environment installed, including the | |
12 | latest versions of DJGPP, GCC, BINUTILS, BASH, etc. This package | |
13 | requires that PERL and BC also be installed. | |

15 | All of these can be obtained from the usual DJGPP mirror sites, such |
16 | as "ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp". You also need to | |
17 | have the WATT-32 networking package installed before you try to compile | |
18 | openssl. This can be obtained from "http://www.bgnett.no/~giva/". | |
19 | The Makefile assumes that the WATT-32 code is in the directory | |
20 | specified by the environment variable WATT_ROOT. If you have watt-32 | |
21 | in directory "watt32" under your main DJGPP directory, specify | |
22 | WATT_ROOT="/dev/env/DJDIR/watt32". | |

24 | To compile openssl, start your BASH shell. Then configure for DOS by | |
25 | running "./Configure" with appropriate arguments. The basic syntax for | |
26 | DOS is: | |
27 | ./Configure no-threads --prefix=/dev/env/DJDIR DJGPP | |
28 | ||
29 | You may run out of DPMI selectors when running in a DOS box under | |
30 | Windows. If so, just close the BASH shell, go back to Windows, and | |
31 | restart BASH. Then run "make" again. | |
32 | ||
33 | Building openssl under DJGPP has been tested with DJGPP 2.03, | |
34 | GCC 2.952, GCC 2.953, perl 5.005_02 and perl 5.006_01. |
