I have just finished porting the 0.9.6 version of openssl to DOS via
the DJGPP compiling environment. I know that Gisle Vanem had commented
on the ability to compile openssl under DJGPP in February and April
of this year, but I didn't see a patch to make this go smoothly. The
main obstacle to the port was the assumption in several places that
symbolic links are available in the operating system, an assumption
not true in DOS. This problem starts with the tar.gz archive. The DJTAR
program tries to convert symbolic links into hard links (by copying the
file), but only 0 byte files are created, because the symbolic links are
unpacked before the file itself.
With this patch openssl compiles without problem. The only warnings
are of unused parameters, missing initializers, and comparisons
between signed and unsigned. Make test has no errors. Make install
seems to work properly also. The DJGPP port of the lynx browser
compiled with the openssl library works well, connecting to secure
sites.
Please note that I am not a programmer and have never worked with
perl before. Nonetheless, I have checked the patch and it seems to
work properly. The changes in regard to handling of symbolic links
shouldn't break other platforms. Compiling instructions are in the
file install.djgpp, included in the patch file. Any suggestions for
improving this would be appreciated.
Doug

+ 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
+ "http://www.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 directory "watt" under
+ $DJDIR.
+
+ To compile openssl, start your BASH shell. The tar.gz file doesn't
+ unpack properly on DOS because of lack of symbolic links. After you
+ unpack the openssl archive, run "./djcopy.sh" to copy files that
+ couldn't be symbolically linked. Then configure for DOS by running
+ "./Configure" with appropriate arguments. The basic syntax for DOS is:
+ "./Configure no-threads DJGPP". Then run "make" and "make test". 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 only been tested with DJGPP 2.03,
+ GCC 2.952, and perl 5.005_02.
