In addition to the requirements and instructions listed in INSTALL.md, this are required as well:
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 (aka 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.
It seems that the perl function canonpath() in the
doesn't treat file specifications where the last directory name
contains periods very well. Unfortunately, some versions of VMS tar
will keep the periods in the OpenSSL source directory instead of
converting them to underscore, thereby leaving your source in
[.openssl-1^.1^.0]. This will lead to issues when
configuring and building OpenSSL.
We have no replacement for Perl's canonpath(), so the best workaround for now is to rename the OpenSSL source directory, as follows (please adjust for the actual source directory name you have):
$ rename openssl-1^.1^.0.DIR openssl-1_1_0.DIR
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.
If you build for debugging, the default on VMS is that image activation starts the debugger automatically, giving you a debug prompt. Unfortunately, this disrupts all other uses, such as running test programs in the test framework.
Generally speaking, if you build for debugging, only use the programs directly for debugging. Do not try to use them from a script, such as running the test suite.
As a compromise, we're turning off the flag that makes the debugger start automatically. If there is a program that you need to debug, you need to turn that flag back on first, for example:
$ set image /flag=call_debug [.test]evp_test.exe
Then just run it and you will find yourself in a debugging session. When done, we recommend that you turn that flag back off:
$ set image /flag=nocall_debug [.test]evp_test.exe
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 that this file exists:
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
VMSTAR to unpack the resulting tar file.
Gzip and VMSTAR are available here:
Should you need it, you can find UnZip for VMS here:
'arch' is mentioned in INSTALL. It's value is determined like this:
arch = f$edit( f$getsyi( "arch_name"), "upcase")
