NAME

SYNOPSIS

 use ExtUtils::MM_VMS; # Done internally by ExtUtils::MakeMaker if needed

DESCRIPTION

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.

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

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 to check for executable image, and .Com to check for DCL procedure. If this fails, checks Sys$Share: for an executable file having the name specified. Finally, appends .Exe and checks again.

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 .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.

const_loadlibs (override)

Basically a stub which passes through library specfications provided by the caller. Will be updated or removed when VMS support is added to ExtUtils::Liblist.

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, and do the same with /Includes, since some C compilers pay attention to only one instance of these qualifiers 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.

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.

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.
