Requirement details
In addition to the requirements and instructions listed in INSTALL,
this 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) and require
version 7.1 or later. Compiling with a different ANSI C compiler may
require some work.
Please avoid using C RTL feature logical names DECC$* when building
and testing OpenSSL. Most of all, they can be disruptive when
running the tests, as they affect the Perl interpreter.
About MMS and DCL
MMS has certain limitations when it comes to line length, and DCL has
certain limitations when it comes to total command length. We do
what we can to mitigate, but there is the possibility that it's not
enough. Should you run into issues, a very simple solution is to set
yourself up a few logical names for the directory trees you're going
to use.
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:
The best way to get a correct distribution is to download the gzipped
tar file from, use GZIP -d to uncompress
it and VMSTAR to unpack the resulting tar file.
Gzip and VMSTAR are available here:
Should you need it, you can find UnZip for VMS here:
