+=head2 Introduction to Perl on VMS
The VMS port of Perl is as functionally complete as any other Perl port
(and as complete as the ports on some Unix systems). The Perl binaries
relatively modern version, check the "DEC C issues" section later on in this
document.

@ Configure "-d" "-Dprefix=dka100:[utils.perl5.]"
+Note that the installation location would be by default where you unpacked
+the source with a "_ROOT." appended. For example if you unpacked the perl
+source into:
+
+ DKA200:[PERL-5_10_2...]
+
+Then the PERL_SETUP.COM that gets written out by CONFIGURE.COM will
+try to DEFINE your installation PERL_ROOT to be:

below.
-=head2 Changing compile-time options (optional)
+=head2 Changing compile-time options (optional) for Perl on VMS
Most of the user definable features of Perl are enabled or disabled in
-[.VMS]CONFIG.VMS. There is code in there to Do The Right Thing, but that
-may end up being the wrong thing for you. Make sure you understand what
-you are doing since inappropriate changes to CONFIG.VMS can render perl
-unbuildable.
-
-Odds are that there's nothing here to change, unless you're on a version of
-VMS later than 6.2 and DEC C later than 5.6. Even if you are, the correct
-values will still be chosen, most likely. Poking around here should be
-unnecessary.
+configure.com, which processes the hints file config_h.SH. There is
+code in there to Do The Right Thing, but that may end up being the
+wrong thing for you. Make sure you understand what you are doing since
+inappropriate changes to configure.com or config_h.SH can render perl
+unbuildable; odds are that there's nothing in there you'll need to
+change.
The one exception is the various *DIR install locations. Changing those
requires changes in genconfig.pl as well. Be really careful if you need to
change these, as they can cause some fairly subtle problems.
-=head2 Socket Support (optional)
+=head2 Socket Support (optional) for Perl on VMS
Perl includes a number of functions for IP sockets, which are available if
you choose to compile Perl with socket support. Since IP networking is an
MMK you are running try "MMS/ident" or "MMK /ident". The GNU make version
can be identified with "make --version".
-=head2 Cleaning up and starting fresh (optional)
+=head2 Cleaning up and starting fresh (optional) installing Perl on VMS
If you need to recompile from scratch, you have to make sure you clean up
first. There is a procedure to do it--enter the *exact* MMS line you used
See also the "INSTALLing images (optional)" section.
-=head2 Installing Perl into DCLTABLES (optional)
+=head2 Installing Perl into DCLTABLES (optional) on VMS
Execute the following command file to define PERL as a DCL command.
You'll need CMKRNL privilege to install the new dcltables.exe.
$ install replace sys$common:[syslib]dcltables.exe
$ exit
-=head2 INSTALLing images (optional)
+=head2 INSTALLing Perl images (optional) on VMS
On systems that are using perl quite a bit, and particularly those with
minimal RAM, you can boost the performance of perl by INSTALLing it as
-a known image. PERLSHR.EXE is typically larger than 2500 blocks
+a known image. PERLSHR.EXE is typically larger than 3000 blocks
and that is a reasonably large amount of IO to load each time perl is
invoked.
While there is code in perl to remove privileges as it runs you are advised
to NOT INSTALL PERL.EXE with PRIVs!
+=head2 Running h2ph to create perl header files (optional) on VMS
+
+If using DEC C or Compaq C ensure that you have extracted loose versions
+of your compiler's header or *.H files. Be sure to check the contents of:
+
+ SYS$LIBRARY:DECC$RTLDEF.TLB
+ SYS$LIBRARY:SYS$LIB_C.TLB
+ SYS$LIBRARY:SYS$STARLET_C.TLB
+
+etcetera.
+
+If using GNU cc then also check your GNU_CC:[000000...] tree for the locations
+of the GNU cc headers.
+
=head1 Reporting Bugs
If you come across what you think might be a bug in Perl, please report
The next big gotcha is directory depth. Perl can create directories four,
five, or even six levels deep during the build, so you don't have to be
-too deep to start to hit the RMS 8 level limit (for versions of VMS prior
-to V7.2 and even with V7.2 on the VAX). It is best to do
+too deep to start to hit the RMS 8 level limit (for ODS 2 volumes which were
+common on versions of VMS prior to V7.2 and even with V7.2 on the VAX).
+It is best to do:
DEFINE/TRANS=(CONC,TERM) PERLSRC "disk:[dir.dir.dir.perldir.]"
SET DEFAULT PERLSRC:[000000]
build. If things go wrong make sure you do a "(MMK|MMS|make) realclean"
before you rebuild.
-=head2 DEC C issues
+=head2 DEC C issues with Perl on VMS
Note to DEC C users: Some early versions (pre-5.2, some pre-4. If you're DEC
C 5.x or higher, with current patches if any, you're fine) of the DECCRTL
Perl exited. This is fixed by DEC CSC patch ALPACRT04_061 or later.
