Subject: | ANNOUNCE: DJGPP port of OpenSSL 1.0.1c uploaded.

This is a port of OpenSSL 1.0.1c to MSDOS/DJGPP.
The OpenSSL Project is an Open Source toolkit implementing the Secure Sockets
Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as
a full-strength general purpose cryptography library. OpenSSL is based on
the excellent SSLeay library developed from Eric A. Young and Tim J. Hudson.
The OpenSSL toolkit is licensed under a dual-license (the OpenSSL license
plus the SSLeay license) situation, which basically means that you are free
to get and use it for commercial and non-commercial purposes as long as you
fulfill the conditions of both licenses.
DJGPP specific changes.
=======================
Fortunately, OpenSSL supports DJGPP out-of-the-box so there is no need to
adjust the source code itself. Neitherless there are assumptions made about
the file system used and its capabilities that require some changes in the
perl configuration scripts and in the way source package is unzipped.
- all new DJGPP specific files are store in the /djgpp directory.
- to install, configure and compile the sources LFN support is required.
- all links (linked files) in the archive have been removed. Depending on if
djtar or tar is used and depending on if they are from DJGPP 2.03 or 2.04
all these tar programs create different kind of files to represent those
links and this breaks either the configuration step or later the building
step.
- the /djgpp directory contains unpack.sh. This small shell script uses
djtar to create a file list of the archive, identifies the links, extract
the sources using djtar and removes all links. Of course, if you download
the DJGPP port all this has already been done.
- as usual the /djgpp directory contains also the diffs file. It shows how
I have changed some of the perl scripts used during the configuration and
building steps to check for the OS used and to copy the files instead of
trying to create links even if this is possible.
- the binaries, headers and libraries will be installed in the corresponding
directories of the DJGPP installation tree. All documentation will be
installend in /dev/env/DJDIR/share/ssl/man. This means that you will have
to adjust your MANPATH in djgpp.env if you want that the man program finds
these new manpages.
- to be able to configure and compile this port, the DJGPP port of perl must
be installed. openssl uses a mix of perl scripts and Makefiles to configure
and compile the sources. I have used perl588b but the previous one may work
as well but I have never tested this.
- Attention: this port depends on WATT-32. Unfortunately there is no DJGPP
specific port available that fits into the DJGPP installation tree so I
downloaded the source archive and compiled it.
I have used watt32s-2.2-dev.10.zip. I had to adjust the following issues:
1) the error numbers list (/src/djgpp/syserr.c) generated by /util/dj_err.exe
does not match the error numbers of DJGPP 2.04, so I have deleted that
program and compiled it again using djdev204. If this is not done a
lot of warnings concerning redefined error numbers will be generated.
Of course, to compile the DJGPP 2.03 port of openssl I have compiled
/util/dj_err.exe with djdev203. The error list must always match the
djdev version that shall be used.
2) I have removed the -gcoff flag from the CFLAGS variable in /src/djgpp.mak.
If this is not done a brocken library will be produced and every single
openssl program created by the testsuite that is linked with libwatt.a
dies with SIGSEGV. Of course, it is well known that the COFF debug
support for the latest GCC compilers is almost completely brocken; using
other versions previous to gcc4NN may work well with -gcoff.
I have never tested the binary distribution of WATT-32 but I fear that
it will not work with gcc4NN and this DJGPP port of openssl.
The buttom line is that you must install the WATT-32 sources in some
directory, configure and compile it either for DJGPP 2.03 or DJGPP 2.04 and
make the WATT_ROOT environment variable point to that directory before you
can configure and compile openssl.
- the binary package of openssl ist not completely SFN clean. But this
concerns the manpages only. Neither the libraries nor the headers are
affected. I do not have the time to invent SFN clean names for hundreds
of manpages which names may change and become useless with the next openssl
update. Of course, the headers and libraries are 8.3 clean and the use of
the libraries do not require LFN support at all.
- the openssl libraries depend on WATT-32, so the WATT-32 headers and library
must be installed somewhere on your hard disk when you link your application
with openssl. Remember to set the WATT_ROOT environment variable to point
to the directory where your installed WATT-32. This does not need to be
the same directory where WATT-32 was installed when openssl was configured
and build.
- the testsuite passes for both djdev203 and djdev204 except for the last test
that requires some certificate that needs to be requested. For some test,
it is also required that the port of GNU bc is installed.
- due to the dependency of WATT-32 and the required value of the WATT_ROOT
environment variable, the source package is not configured at all. You
have to install and build WATT-32 first and then you can configure and
build openssl as described in the original INSTALL.DJGPP file.
- as any cryptographic software, openssl 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 of openssl the 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" as:
<http://www.rahul.net/dkaufman/noise063a2.zip>
Please read the instructions _VERY_ carefully. This driver works on DOS
and may be on some versions of Windows (Windows 3.1 and Win95) but it does
not work for all versions of Windows. For XP it does not work and I have
found no replacement. This means that for WinXP and probably for Win2K
there is no "randomness device" support for openssl available.
- the port has been configured and compiled to support for zlib compression.
The zlib port used is
ftp://ftp.delorie.com/pub/djgpp/current/v2tk/zlib127b.zip
or:
ftp://ftp.delorie.com/pub/djgpp/beta/v2tk/zlib127b.zip
but any other version of the port may work as well.
- the binaries have been build on WinXP using djdev203 or djdev204, gcc471b
and bnu222br4.
Configuring, compiling and running the testsuite takes around 01:30 h not
counting the time to build WATT-32.
For further information about OpenSSL please read the man pages,
various README files and NEWS file. Also visit the home page of openssl.
Please note that I am not an user of openssl. I have only ported it because
I needed it to create another port. This means that I am not able to answer
openssl specific questions.
The port has been compiled using stock djdev203 (patchlevel 2) and consists
of two packages that can be downloaded from ftp.delorie.com and mirrors as
