Change the INSTALL documentation for unified builds

Browse Source 
Because of the unified scheme, building on different platforms is very
similar.  We currently have Unix and OpenVMS on the unified scheme,
which means that a separate INSTALL.VMS is no longer needed.

1c. Configure OpenSSL for building outside of the source tree.
OpenSSL can be configured to build in a build directory separate from
the directory with the source code. It's done by placing yourself in
some other directory and invoking the configuration commands from
there.
Unix example:
$ mkdir /var/tmp/openssl-build
$ cd /var/tmp/openssl-build
$ /PATH/TO/OPENSSL/SOURCE/config [options]

Paths can be relative just as well as absolute. Configure will
do its best to translate them to relative paths whenever possible.

installation target paths.
NOTE: The header files used to reside directly in the include
directory, but have now been moved to include/openssl so that
OpenSSL can co-exist with other libraries which use some of the
same filenames. This means that applications that use OpenSSL
should now use C preprocessor directives of the form
#include <openssl/ssl.h>
instead of "#include <ssl.h>", which was used with library versions
up to OpenSSL 0.9.2b.
If you install a new version of OpenSSL over an old library version,
you should delete the old header files in the include directory.
Compatibility issues:
Compatibility issues with previous OpenSSL versions:
* COMPILING existing applications
To compile an application that uses old filenames -- e.g.
"#include <ssl.h>" --, it will usually be enough to find
the CFLAGS definition in the application's Makefile and
add a C option such as
OpenSSL 1.1 hides a number of structures that were previously
open. This includes all internal libssl structures and a number
of EVP types. Accessor functions have been added to allow
controlled access to the structures' data.
-I/usr/local/ssl/include/openssl
This means that some software needs to be rewritten to adapt to
the new ways of doing things. This often amounts to allocating
an instance of a structure explicitly where you could previously
allocate them on the stack as automatic variables, and using the
provided accessor functions where you would previously access a
structure's field directly.
to it.
<TBA>
But don't delete the existing -I option that points to
the ..../include directory! Otherwise, OpenSSL header files
could not #include each other.
* WRITING applications
To write an application that is able to handle both the new
and the old directory layout, so that it can still be compiled
with library versions up to OpenSSL 0.9.2b without bothering
the user, you can proceed as follows:
- Always use the new filename of OpenSSL header files,
e.g. #include <openssl/ssl.h>.
- Create a directory "incl" that contains only a symbolic
link named "openssl", which points to the "include" directory
of OpenSSL.
For example, your application's Makefile might contain the
following rule, if OPENSSLDIR is a pathname (absolute or
relative) of the directory where OpenSSL resides:
incl/openssl:
-mkdir incl
cd $(OPENSSLDIR) # Check whether the directory really exists
-ln -s `cd $(OPENSSLDIR); pwd`/include incl/openssl
You will have to add "incl/openssl" to the dependencies
of those C files that include some OpenSSL header file.
- Add "-Iincl" to your CFLAGS.
With these additions, the OpenSSL header files will be available
under both name variants if an old library version is used:
Your application can reach them under names like <openssl/foo.h>,
while the header files still are able to #include each other
with names of the form <foo.h>.
Some APIs have changed as well. However, older APIs have been
preserved when possible.

Note on support for multiple builds
-----------------------------------
OpenSSL is usually built in its source tree. Unfortunately, this doesn't
support building for multiple platforms from the same source tree very well.
It is however possible to build in a separate tree through the use of lots
of symbolic links, which should be prepared like this:
mkdir -p objtree/"`uname -s`-`uname -r`-`uname -m`"
cd objtree/"`uname -s`-`uname -r`-`uname -m`"
(cd $OPENSSL_SOURCE; find . -type f) | while read F; do
mkdir -p `dirname $F`
rm -f $F; ln -s $OPENSSL_SOURCE/$F $F
echo $F '->' $OPENSSL_SOURCE/$F
done
make -f Makefile.in clean
OPENSSL_SOURCE is an environment variable that contains the absolute (this
is important!) path to the OpenSSL source tree.
Also, operations like 'make update' should still be made in the source tree.

INSTALLATION ON THE VMS PLATFORM
--------------------------------
Intro
-----
This file is divided in the following parts:
Requirements - Mandatory reading.
Cheking the distribution - Mandatory reading.
Quick start
Test <TO BE ADDED>
Installation <TO BE ADDED>
Backward portability <TO BE ADDED>
Possible bugs and quirks <TO BE ADDED>
Requirements
------------
To build and install OpenSSL, you will need:
* Perl 5 with core modules (please read README.PERL)
* The perl module Text::Template (please read README.PERL)
* DEC C or some other ANSI C compiler. VAX C is *not* supported.
[Note: OpenSSL has only been tested with DEC C. Compiling with
a different ANSI C compiler may require some work]
Checking the distribution
-------------------------
There have been reports of places where the distribution didn't quite
get through, for example if you've copied the tree from a NFS-mounted
Unix mount point.
The easiest way to check if everything got through as it should is to
check for one of the following files:
[.crypto]opensslconf^.h.in
The best way to get a correct distribution is to download the gzipped
tar file from ftp://ftp.openssl.org/source/, use GUNZIP to uncompress
it and use VMSTAR to unpack the resulting tar file.
GUNZIP is available {FIXME: where is it available?}
VMSTAR is available {FIXME: where is it available?}
Quick start
-----------
If you want to just get on with it, do this:
$ @config
$ mms
$ mms test
$ mmm install
This will buidl and install OpenSSL in the default location, which is
SYS$COMMON:[OPENSSL-'VERSION']. If you want it to be anywhere else,
run config.com like this:
$ @config --prefix=PROGRAM:[OPENSSL]

NOTES FOR THE OPENVMS PLATFORM
==============================
Requirement details
-------------------
In addition to the requirements listed in INSTALL, these are required
as well:
* At least ODS-5 disk organization for source and build.
Installation can be done on any existing disk organization.
About ANSI C compiler
---------------------
An ANSI C compiled is needed among other things. This means that VAX C
is not and will not be supported.
We have only tested with DEC C (a.k.a HP VMS C / VSI C), compiling with
a different ANSI C compiler may require some work.
Checking the distribution
-------------------------
There have been reports of places where the distribution didn't quite
get through, for example if you've copied the tree from a NFS-mounted
Unix mount point.
The easiest way to check if everything got through as it should is to
check for one of the following files:
[.crypto]opensslconf^.h.in
The best way to get a correct distribution is to download the gzipped
tar file from ftp://ftp.openssl.org/source/, use GZIP -d to uncompress
it and VMSTAR to unpack the resulting tar file.
