| INSTALLATION ON THE DOS PLATFORM WITH DJGPP | |
| ------------------------------------------- | |
| Openssl has been ported to 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, such | |
| as "ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp". 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 DOS by | |
| running "./Configure" with appropriate arguments. The basic syntax for | |
| DOS is: | |
| ./Configure no-threads --prefix=/dev/env/DJDIR DJGPP | |
| 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. | |
| Building openssl under DJGPP has been tested with DJGPP 2.03, | |
| GCC 2.952, GCC 2.953, perl 5.005_02 and perl 5.006_01. |
