| 11 | Requirement details
|
|---|
| 12 | -------------------
|
|---|
| 13 |
|
|---|
| 14 | In addition to the requirements and instructions listed
|
|---|
| 15 | in [INSTALL.md](INSTALL.md), this are required as well:
|
|---|
| 16 |
|
|---|
| 17 | * At least ODS-5 disk organization for source and build.
|
|---|
| 18 | Installation can be done on any existing disk organization.
|
|---|
| 19 |
|
|---|
| 20 | About ANSI C compiler
|
|---|
| 21 | ---------------------
|
|---|
| 22 |
|
|---|
| 23 | An ANSI C compiled is needed among other things. This means that
|
|---|
| 24 | VAX C is not and will not be supported.
|
|---|
| 25 |
|
|---|
| 26 | We have only tested with DEC C (aka HP VMS C / VSI C) and require
|
|---|
| 27 | version 7.1 or later. Compiling with a different ANSI C compiler may
|
|---|
| 28 | require some work.
|
|---|
| 29 |
|
|---|
| 30 | Please avoid using C RTL feature logical names `DECC$*` when building
|
|---|
| 31 | and testing OpenSSL. Most of all, they can be disruptive when
|
|---|
| 32 | running the tests, as they affect the Perl interpreter.
|
|---|
| 33 |
|
|---|
| 34 | About ODS-5 directory names and Perl
|
|---|
| 35 | ------------------------------------
|
|---|
| 36 |
|
|---|
| 37 | It seems that the perl function canonpath() in the `File::Spec` module
|
|---|
| 38 | doesn't treat file specifications where the last directory name
|
|---|
| 39 | contains periods very well. Unfortunately, some versions of VMS tar
|
|---|
| 40 | will keep the periods in the OpenSSL source directory instead of
|
|---|
| 41 | converting them to underscore, thereby leaving your source in
|
|---|
| 42 | something like `[.openssl-1^.1^.0]`. This will lead to issues when
|
|---|
| 43 | configuring and building OpenSSL.
|
|---|
| 44 |
|
|---|
| 45 | We have no replacement for Perl's canonpath(), so the best workaround
|
|---|
| 46 | for now is to rename the OpenSSL source directory, as follows (please
|
|---|
| 47 | adjust for the actual source directory name you have):
|
|---|
| 48 |
|
|---|
| 49 | $ rename openssl-1^.1^.0.DIR openssl-1_1_0.DIR
|
|---|
| 50 |
|
|---|
| 51 | About MMS and DCL
|
|---|
| 52 | -----------------
|
|---|
| 53 |
|
|---|
| 54 | MMS has certain limitations when it comes to line length, and DCL has
|
|---|
| 55 | certain limitations when it comes to total command length. We do
|
|---|
| 56 | what we can to mitigate, but there is the possibility that it's not
|
|---|
| 57 | enough. Should you run into issues, a very simple solution is to set
|
|---|
| 58 | yourself up a few logical names for the directory trees you're going
|
|---|
| 59 | to use.
|
|---|
| 60 |
|
|---|
| 61 | About debugging
|
|---|
| 62 | ---------------
|
|---|
| 63 |
|
|---|
| 64 | If you build for debugging, the default on VMS is that image
|
|---|
| 65 | activation starts the debugger automatically, giving you a debug
|
|---|
| 66 | prompt. Unfortunately, this disrupts all other uses, such as running
|
|---|
| 67 | test programs in the test framework.
|
|---|
| 68 |
|
|---|
| 69 | Generally speaking, if you build for debugging, only use the programs
|
|---|
| 70 | directly for debugging. Do not try to use them from a script, such
|
|---|
| 71 | as running the test suite.
|
|---|
| 72 |
|
|---|
| 73 | ### The following is not available on Alpha
|
|---|
| 74 |
|
|---|
| 75 | As a compromise, we're turning off the flag that makes the debugger
|
|---|
| 76 | start automatically. If there is a program that you need to debug,
|
|---|
| 77 | you need to turn that flag back on first, for example:
|
|---|
| 78 |
|
|---|
| 79 | $ set image /flag=call_debug [.test]evp_test.exe
|
|---|
| 80 |
|
|---|
| 81 | Then just run it and you will find yourself in a debugging session.
|
|---|
| 82 | When done, we recommend that you turn that flag back off:
|
|---|
| 83 |
|
|---|
| 84 | $ set image /flag=nocall_debug [.test]evp_test.exe
|
|---|
| 85 |
|
|---|
| 86 | About assembler acceleration
|
|---|
| 87 | ----------------------------
|
|---|
| 88 |
|
|---|
| 89 | OpenSSL has assembler acceleration for a number of BIGNUM and crypto
|
|---|
| 90 | routines. The VMS config targets tries to look for a selection of
|
|---|
| 91 | assemblers and will use what they find. If none of the assemblers are
|
|---|
| 92 | found, OpenSSL will be built as if `no-asm` was configured.
|
|---|
| 93 |
|
|---|
| 94 | ### For Itanium / IA64 / I64
|
|---|
| 95 |
|
|---|
| 96 | - There is only one assembler, a port of Intel's `ias`, found in the
|
|---|
| 97 | HP Open Source Tools CD, available through [DECUSlib](http://www.decuslib.com).
|
|---|
| 98 | It's assumed to be set up as per the instructions, where `disk` and
|
|---|
| 99 | `dir` are expected to be adapted to local conditions:
|
|---|
| 100 |
|
|---|
| 101 | $ ias :== $disk:[dir]iasi64.exe
|
|---|
| 102 |
|
|---|
| 103 | Checking the distribution
|
|---|
| 104 | -------------------------
|
|---|
| 105 |
|
|---|
| 106 | There have been reports of places where the distribution didn't quite
|
|---|
| 107 | get through, for example if you've copied the tree from a NFS-mounted
|
|---|
| 108 | Unix mount point.
|
|---|
| 109 |
|
|---|
| 110 | The easiest way to check if everything got through as it should is to
|
|---|
| 111 | check that this file exists:
|
|---|
| 112 |
|
|---|
| 113 | [.include.openssl]configuration^.h.in
|
|---|
| 114 |
|
|---|
| 115 | The best way to get a correct distribution is to download the gzipped
|
|---|
| 116 | tar file from ftp://ftp.openssl.org/source/, use `GZIP -d` to uncompress
|
|---|
| 117 | it and `VMSTAR` to unpack the resulting tar file.
|
|---|
| 118 |
|
|---|
| 119 | Gzip and VMSTAR are available here:
|
|---|
| 120 |
|
|---|
| 121 | <http://antinode.info/dec/index.html#Software>
|
|---|
| 122 |
|
|---|
| 123 | Should you need it, you can find UnZip for VMS here:

| 127 | How the value of 'arch' is determined
|
|---|
| 128 | -------------------------------------
|
|---|
| 129 |
|
|---|
| 130 | 'arch' is mentioned in INSTALL. It's value is determined like this:
|
|---|
| 131 |
|
|---|
| 132 | arch = f$edit( f$getsyi( "arch_name"), "upcase")
|
|---|
