NAME
ExtUtils::MM_VMS - methods to override UN*X behaviour in
ExtUtils::MakeMaker
SYNOPSIS
use ExtUtils::MM_VMS; # Done internally by ExtUtils::MakeMaker if needed
DESCRIPTION
See ExtUtils::MM_Unix for a documentation of the methods provided there.
This package overrides the implementation of these methods, not the
semantics.
Methods always loaded
eliminate_macros
Expands MM[KS]/Make macros in a text string, using the contents of
identically named elements of %$self, and returns the result as a
file specification in Unix syntax.
fixpath
Catchall routine to clean up problem MM[SK]/Make macros. Expands
macros in any directory specification, in order to avoid juxtaposing
two VMS-syntax directories when MM[SK] is run. Also expands
expressions which are all macro, so that we can tell how long the
expansion is, and avoid overrunning DCL's command buffer when MM[KS]
is running.
If optional second argument has a TRUE value, then the return string
is a VMS-syntax directory specification, otherwise it is a
VMS-syntax file specification.
catdir
Concatenates a list of file specifications, and returns the result
as a VMS-syntax directory specification.
catfile
Concatenates a list of file specifications, and returns the result
as a VMS-syntax directory specification.
wraplist
Converts a list into a string wrapped at approximately 80 columns.
curdir (override)
Returns a string representing of the current directory.
rootdir (override)
Returns a string representing of the root directory.
updir (override)
Returns a string representing of the parent directory.

SelfLoaded methods
Those methods which override default MM_Unix methods are marked
"(override)", while methods unique to MM_VMS are marked "(specific)".
For overridden methods, documentation is limited to an explanation of why
this method overrides the MM_Unix method; see the ExtUtils::MM_Unix
documentation for more details.
guess_name (override)
Try to determine name of extension being built. We begin with the
name of the current directory. Since VMS filenames are case-
insensitive, however, we look for a .pm file whose name matches that
of the current directory (presumably the 'main' .pm file for this
extension), and try to find a package statement from which to obtain
the Mixed::Case package name.
find_perl (override)
Use VMS file specification syntax and CLI commands to find and
invoke Perl images.
path (override)
Translate logical name DCL$PATH as a searchlist, rather than trying
to split string value of $ENV{'PATH'}.
maybe_command (override)
Follows VMS naming conventions for executable files. If the name
passed in doesn't exactly match an executable file, appends .Exe (or
equivalent) to check for executable image, and .Com to check for DCL
procedure. If this fails, checks directories in DCL$PATH and
finally Sys$System: for an executable file having the name
specified, with or without the .Exe-equivalent suffix.
maybe_command_in_dirs (override)
Uses DCL argument quoting on test command line.
perl_script (override)
If name passed in doesn't specify a readable file, appends .com or
.pl and tries again, since it's customary to have file types on all
files under VMS.
file_name_is_absolute (override)
Checks for VMS directory spec as well as Unix separators.
replace_manpage_separator
Use as separator a character which is legal in a VMS-syntax file
name.
init_others (override)
Provide VMS-specific forms of various utility commands, then hand
off to the default MM_Unix method.

constants (override)
Fixes up numerous file and directory macros to insure VMS syntax
regardless of input syntax. Also adds a few VMS-specific macros and
makes lists of files comma-separated.
cflags (override)
Bypass shell script and produce qualifiers for CC directly (but warn
user if a shell script for this extension exists). Fold multiple
/Defines into one, since some C compilers pay attention to only one
instance of this qualifier on the command line.
const_cccmd (override)
Adds directives to point C preprocessor to the right place when
handling #include <sys/foo.h> directives. Also constructs CC
command line a bit differently than MM_Unix method.
pm_to_blib (override)
DCL still accepts a maximum of 255 characters on a command line, so
we write the (potentially) long list of file names to a temp file,
then persuade Perl to read it instead of the command line to find
args.
tool_autosplit (override)
Use VMS-style quoting on command line.
tool_sxubpp (override)
Use VMS-style quoting on xsubpp command line.
xsubpp_version (override)
Test xsubpp exit status according to VMS rules ($sts & 1 ==> good)
rather than Unix rules ($sts == 0 ==> good).
tools_other (override)
Adds a few MM[SK] macros, and shortens some the installatin
commands, in order to stay under DCL's 255-character limit. Also
changes EQUALIZE_TIMESTAMP to set revision date of target file to
one second later than source file, since MMK interprets precisely
equal revision dates for a source and target file as a sign that the
target needs to be updated.
dist (override)
Provide VMSish defaults for some values, then hand off to default
MM_Unix method.
c_o (override)
Use VMS syntax on command line. In particular, $(DEFINE) and
$(PERL_INC) have been pulled into $(CCCMD). Also use MM[SK] macros.
xs_c (override)
Use MM[SK] macros.

ExtUtils::MMVMS(3) ExtUtils::MMVMS(3)
xs_o (override)
Use MM[SK] macros, and VMS command line for C compiler.
top_targets (override)
Use VMS quoting on command line for Version_check.
dlsyms (override)
Create VMS linker options files specifying universal symbols for
this extension's shareable image, and listing other shareable images
or libraries to which it should be linked.
dynamic_lib (override)
Use VMS Link command.
dynamic_bs (override)
Use VMS-style quoting on Mkbootstrap command line.
static_lib (override)
Use VMS commands to manipulate object library.
manifypods (override)
Use VMS-style quoting on command line, and VMS logical name to
specify fallback location at build time if we can't find pod2man.
processPL (override)
Use VMS-style quoting on command line.
installbin (override)
Stay under DCL's 255 character command line limit once again by
splitting potentially long list of files across multiple lines in
realclean target.
subdir_x (override)
Use VMS commands to change default directory.
clean (override)
Split potentially long list of files across multiple commands (in
order to stay under the magic command line limit). Also use MM[SK]
commands for handling subdirectories.
realclean (override)
Guess what we're working around? Also, use MM[SK] for
subdirectories.
dist_basics (override)
Use VMS-style quoting on command line.
dist_core (override)
Syntax for invoking VMS_Share differs from that for Unix shar, so
shdist target actions are VMS-specific.

ExtUtils::MMVMS(3) ExtUtils::MMVMS(3)
dist_dir (override)
Use VMS-style quoting on command line.
dist_test (override)
Use VMS commands to change default directory, and use VMS-style
quoting on command line.
install (override)
Work around DCL's 255 character limit several times,and use
VMS-style command line quoting in a few cases.
perldepend (override)
Use VMS-style syntax for files; it's cheaper to just do it directly
here than to have the MM_Unix method call catfile repeatedly. Also
use config.vms as source of original config data if the Perl
distribution is available; config.sh is an ancillary file under VMS.
Finally, if we have to rebuild Config.pm, use MM[SK] to do it.
makefile (override)
Use VMS commands and quoting.
test (override)
Use VMS commands for handling subdirectories.
test_via_harness (override)
Use VMS-style quoting on command line.
test_via_script (override)
Use VMS-style quoting on command line.
makeaperl (override)
Undertake to build a new set of Perl images using VMS commands.
Since VMS does dynamic loading, it's not necessary to statically
link each extension into the Perl image, so this isn't the normal
build path. Consequently, it hasn't really been tested, and may
well be incomplete.
nicetext (override)
Insure that colons marking targets are preceded by space, in order
to distinguish the target delimiter from a colon appearing as part
of a filespec.
