   2  NOTES FOR THE OPENVMS PLATFORM
   3  ==============================
   4
   5  Requirement details
   6  -------------------
   7
   8  In addition to the requirements and instructions listed in INSTALL,
   9  this are required as well:
  10
  11   * At least ODS-5 disk organization for source and build.
  12     Installation can be done on any existing disk organization.
  13
  14
  15  About ANSI C compiler
  16  ---------------------
  17
  18  An ANSI C compiled is needed among other things.  This means that
  19  VAX C is not and will not be supported.
  20
  21  We have only tested with DEC C (a.k.a HP VMS C / VSI C) and require
  22  version 7.1 or later.  Compiling with a different ANSI C compiler may
  23  require some work.
  24
  25  Please avoid using C RTL feature logical names DECC$* when building
  26  and testing OpenSSL.  Most of all, they can be disruptive when
  27  running the tests, as they affect the Perl interpreter.
  28
  29
  30  About ODS-5 directory names and Perl
  31  ------------------------------------
  32
  33  It seems that the perl function canonpath() in the File::Spec module
  34  doesn't treat file specifications where the last directory name
  35  contains periods very well.  Unfortunately, some versions of VMS tar
  36  will keep the periods in the OpenSSL source directory instead of
  37  converting them to underscore, thereby leaving your source in
  38  something like [.openssl-1^.1^.0].  This will lead to issues when
  39  configuring and building OpenSSL.
  40
  41  We have no replacement for Perl's canonpath(), so the best workaround
  42  for now is to rename the OpenSSL source directory, as follows (please
  43  adjust for the actual source directory name you have):
  44
  45     $ rename openssl-1^.1^.0.DIR openssl-1_1_0.DIR
  46
  47
  48  About MMS and DCL
  49  -----------------
  50
  51  MMS has certain limitations when it comes to line length, and DCL has
  52  certain limitations when it comes to total command length.  We do
  53  what we can to mitigate, but there is the possibility that it's not
  54  enough.  Should you run into issues, a very simple solution is to set
  55  yourself up a few logical names for the directory trees you're going
  56  to use.
  57
  58
  59  About debugging
  60  ---------------
  61
  62  If you build for debugging, the default on VMS is that image
  63  activation starts the debugger automatically, giving you a debug
  64  prompt.  Unfortunately, this disrupts all other uses, such as running
  65  test programs in the test framework.
  66
  67  Generally speaking, if you build for debugging, only use the programs
  68  directly for debugging.  Do not try to use them from a script, such
  69  as running the test suite.
  70
  71  *The following is not available on Alpha*
  72
  73  As a compromise, we're turning off the flag that makes the debugger
  74  start automatically.  If there is a program that you need to debug,
  75  you need to turn that flag back on first, for example:
  76
  77     $ set image /flag=call_debug [.test]evp_test.exe
  78
  79  Then just run it and you will find yourself in a debugging session.
  80  When done, we recommend that you turn that flag back off:
  81
  82     $ set image /flag=nocall_debug [.test]evp_test.exe
  83
  84
  85  Checking the distribution
  86  -------------------------
  87
  88  There have been reports of places where the distribution didn't quite
  89  get through, for example if you've copied the tree from a NFS-mounted
  90  Unix mount point.
  91
  92  The easiest way to check if everything got through as it should is to
  93  check for one of the following files:
  94
  95    [.crypto]opensslconf^.h.in
  96
  97  The best way to get a correct distribution is to download the gzipped
  98  tar file from ftp://ftp.openssl.org/source/, use GZIP -d to uncompress
  99  it and VMSTAR to unpack the resulting tar file.
