MSYS在windows下模拟了一个类unix的终端

Hashref of symbol names for routines to be made available as universal
symbols.  Each key/value pair consists of the package name and an
array of routine names in that package.  Used only under AIX, OS/2,
VMS and Win32 at present.  The routine names supplied will be expanded
in the same way as XSUB names are expanded by the XS() macro.
Defaults to

  {"$(NAME)" => ["boot_$(NAME)" ] }

e.g.

  {"RPC" => [qw( boot_rpcb rpcb_gettime getnetconfigent )],
   "NetconfigPtr" => [ 'DESTROY'] }

Please see the L<ExtUtils::Mksymlists> documentation for more information
about the DL_FUNCS, DL_VARS and FUNCLIST attributes.

=item DL_VARS

Array of symbol names for variables to be made available as universal symbols.
Used only under AIX, OS/2, VMS and Win32 at present.  Defaults to [].
(e.g. [ qw(Foo_version Foo_numstreams Foo_tree ) ])

=item EXCLUDE_EXT

Array of extension names to exclude when doing a static build.  This
is ignored if INCLUDE_EXT is present.  Consult INCLUDE_EXT for more
details.  (e.g.  [ qw( Socket POSIX ) ] )

This attribute may be most useful when specified as a string on the
command line:  perl Makefile.PL EXCLUDE_EXT='Socket Safe'

=item EXE_FILES

Ref to array of executable files. The files will be copied to the
INST_SCRIPT directory. Make realclean will delete them from there
again.

=item FIRST_MAKEFILE

The name of the Makefile to be produced. Defaults to the contents of
MAKEFILE, but can be overridden. This is used for the second Makefile
that will be produced for the MAP_TARGET.

=item FULLPERL

Perl binary able to run this extension.

=item FUNCLIST

This provides an alternate means to specify function names to be
exported from the extension.  Its value is a reference to an
array of function names to be exported by the extension.  These
names are passed through unaltered to the linker options file.

=item H

Ref to array of *.h file names. Similar to C.

=item HTMLLIBPODS

Hashref of .pm and .pod files.  MakeMaker will default this to all
 .pod and any .pm files that include POD directives.  The files listed
here will be converted to HTML format and installed as was requested
at Configure time.

=item HTMLSCRIPTPODS

Hashref of pod-containing files.  MakeMaker will default this to all
EXE_FILES files that include POD directives.  The files listed
here will be converted to HTML format and installed as was requested
at Configure time.

=item IMPORTS

This attribute is used to specify names to be imported into the
extension. It is only used on OS/2 and Win32.

=item INC

Include file dirs eg: C<"-I/usr/5include -I/path/to/inc">

=item INCLUDE_EXT

Array of extension names to be included when doing a static build.
MakeMaker will normally build with all of the installed extensions when
doing a static build, and that is usually the desired behavior.  If
INCLUDE_EXT is present then MakeMaker will build only with those extensions
which are explicitly mentioned. (e.g.  [ qw( Socket POSIX ) ])

It is not necessary to mention DynaLoader or the current extension when
filling in INCLUDE_EXT.  If the INCLUDE_EXT is mentioned but is empty then
only DynaLoader and the current extension will be included in the build.

This attribute may be most useful when specified as a string on the
command line:  perl Makefile.PL INCLUDE_EXT='POSIX Socket Devel::Peek'

=item INSTALLARCHLIB

Used by 'make install', which copies files from INST_ARCHLIB to this
directory if INSTALLDIRS is set to perl.

=item INSTALLBIN

Directory to install binary files (e.g. tkperl) into.

=item INSTALLDIRS

Determines which of the two sets of installation directories to
choose: installprivlib and installarchlib versus installsitelib and
installsitearch. The first pair is chosen with INSTALLDIRS=perl, the
second with INSTALLDIRS=site. Default is site.

=item INSTALLHTMLPRIVLIBDIR

This directory gets the HTML pages at 'make install' time. Defaults to
$Config{installhtmlprivlibdir}.

=item INSTALLHTMLSCRIPTDIR

This directory gets the HTML pages at 'make install' time. Defaults to
$Config{installhtmlscriptdir}.

=item INSTALLHTMLSITELIBDIR

This directory gets the HTML pages at 'make install' time. Defaults to
$Config{installhtmlsitelibdir}.


=item INSTALLMAN1DIR

This directory gets the man pages at 'make install' time. Defaults to
$Config{installman1dir}.

=item INSTALLMAN3DIR

This directory gets the man pages at 'make install' time. Defaults to
$Config{installman3dir}.

=item INSTALLPRIVLIB

Used by 'make install', which copies files from INST_LIB to this
directory if INSTALLDIRS is set to perl.

=item INSTALLSCRIPT

Used by 'make install' which copies files from INST_SCRIPT to this
directory.

=item INSTALLSITEARCH

Used by 'make install', which copies files from INST_ARCHLIB to this
directory if INSTALLDIRS is set to site (default).

=item INSTALLSITELIB

Used by 'make install', which copies files from INST_LIB to this
directory if INSTALLDIRS is set to site (default).

=item INST_ARCHLIB

Same as INST_LIB for architecture dependent files.

=item INST_BIN

Directory to put real binary files during 'make'. These will be copied
to INSTALLBIN during 'make install'

=item INST_EXE

Old name for INST_SCRIPT. Deprecated. Please use INST_SCRIPT if you
need to use it.

=item INST_HTMLLIBDIR

Directory to hold the man pages in HTML format at 'make' time

=item INST_HTMLSCRIPTDIR

Directory to hold the man pages in HTML format at 'make' time

=item INST_LIB

Directory where we put library files of this extension while building
it.

=item INST_MAN1DIR

Directory to hold the man pages at 'make' time

=item INST_MAN3DIR

Directory to hold the man pages at 'make' time

=item INST_SCRIPT

Directory, where executable files should be installed during
'make'. Defaults to "./blib/script", just to have a dummy location during
testing. make install will copy the files in INST_SCRIPT to
INSTALLSCRIPT.

=item LDFROM

defaults to "$(OBJECT)" and is used in the ld command to specify
what files to link/load from (also see dynamic_lib below for how to
specify ld flags)

=item LIB

LIB should only be set at C<perl Makefile.PL> time but is allowed as a
MakeMaker argument. It has the effect of
setting both INSTALLPRIVLIB and INSTALLSITELIB to that value regardless any
explicit setting of those arguments (or of PREFIX).  
INSTALLARCHLIB and INSTALLSITEARCH are set to the corresponding 
architecture subdirectory.

=item LIBPERL_A

The filename of the perllibrary that will be used together with this
extension. Defaults to libperl.a.

=item LIBS

An anonymous array of alternative library
specifications to be searched for (in order) until
at least one library is found. E.g.

  'LIBS' => ["-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs"]

Mind, that any element of the array
contains a complete set of arguments for the ld
command. So do not specify

  'LIBS' => ["-ltcl", "-ltk", "-lX11"]

See ODBM_File/Makefile.PL for an example, where an array is needed. If
you specify a scalar as in

  'LIBS' => "-ltcl -ltk -lX11"

MakeMaker will turn it into an array with one element.

=item LINKTYPE

'static' or 'dynamic' (default unless usedl=undef in
config.sh). Should only be used to force static linking (also see
linkext below).

=item MAKEAPERL

Boolean which tells MakeMaker, that it should include the rules to
make a perl. This is handled automatically as a switch by
MakeMaker. The user normally does not need it.

=item MAKEFILE

The name of the Makefile to be produced.

=item MAN1PODS

Hashref of pod-containing files. MakeMaker will default this to all
EXE_FILES files that include POD directives. The files listed
here will be converted to man pages and installed as was requested
at Configure time.

=item MAN3PODS

Hashref of .pm and .pod files. MakeMaker will default this to all
 .pod and any .pm files that include POD directives. The files listed
here will be converted to man pages and installed as was requested
at Configure time.

=item MAP_TARGET

If it is intended, that a new perl binary be produced, this variable
may hold a name for that binary. Defaults to perl

=item MYEXTLIB

If the extension links to a library that it builds set this to the
name of the library (see SDBM_File)

=item NAME

Perl module name for this extension (DBD::Oracle). This will default
to the directory name but should be explicitly defined in the
Makefile.PL.

=item NEEDS_LINKING

MakeMaker will figure out if an extension contains linkable code
anywhere down the directory tree, and will set this variable
accordingly, but you can speed it up a very little bit if you define
this boolean variable yourself.

=item NOECHO

Defaults to C<@>. By setting it to an empty string you can generate a
Makefile that echos all commands. Mainly used in debugging MakeMaker
itself.

=item NORECURS

Boolean.  Attribute to inhibit descending into subdirectories.

=item NO_VC

In general, any generated Makefile checks for the current version of
MakeMaker and the version the Makefile was built under. If NO_VC is
set, the version check is neglected. Do not write this into your
Makefile.PL, use it interactively instead.

=item OBJECT

List of object files, defaults to '$(BASEEXT)$(OBJ_EXT)', but can be a long
string containing all object files, e.g. "tkpBind.o
tkpButton.o tkpCanvas.o"

(Where BASEEXT is the last component of NAME, and OBJ_EXT is $Config{obj_ext}.)

=item OPTIMIZE

Defaults to C<-O>. Set it to C<-g> to turn debugging on. The flag is
passed to subdirectory makes.

=item PERL

Perl binary for tasks that can be done by miniperl

=item PERLMAINCC

The call to the program that is able to compile perlmain.c. Defaults
to $(CC).

=item PERL_ARCHLIB

Same as below, but for architecture dependent files.

=item PERL_LIB

Directory containing the Perl library to use.

=item PERL_MALLOC_OK

defaults to 0.  Should be set to TRUE if the extension can work with
the memory allocation routines substituted by the Perl malloc() subsystem.
This should be applicable to most extensions with exceptions of those

=over 4

=item *

with bugs in memory allocations which are caught by Perl's malloc();

=item *

which interact with the memory allocator in other ways than via
malloc(), realloc(), free(), calloc(), sbrk() and brk();

=item *

which rely on special alignment which is not provided by Perl's malloc().

=back

B<NOTE.>  Negligence to set this flag in I<any one> of loaded extension
nullifies many advantages of Perl's malloc(), such as better usage of
system resources, error detection, memory usage reporting, catchable failure
of memory allocations, etc.

=item PERL_SRC

Directory containing the Perl source code (use of this should be
avoided, it may be undefined)

=item PERM_RW

Desired permission for read/writable files. Defaults to C<644>.
See also L<MM_Unix/perm_rw>.

=item PERM_RWX

Desired permission for executable files. Defaults to C<755>.
See also L<MM_Unix/perm_rwx>.

=item PL_FILES

Ref to hash of files to be processed as perl programs. MakeMaker
will default to any found *.PL file (except Makefile.PL) being keys
and the basename of the file being the value. E.g.

  {'foobar.PL' => 'foobar'}

The *.PL files are expected to produce output to the target files
themselves. If multiple files can be generated from the same *.PL
file then the value in the hash can be a reference to an array of
target file names. E.g.

  {'foobar.PL' => ['foobar1','foobar2']}

=item PM

Hashref of .pm files and *.pl files to be installed.  e.g.

  {'name_of_file.pm' => '$(INST_LIBDIR)/install_as.pm'}

By default this will include *.pm and *.pl and the files found in
the PMLIBDIRS directories.  Defining PM in the
Makefile.PL will override PMLIBDIRS.

=item PMLIBDIRS

Ref to array of subdirectories containing library files.  Defaults to
[ 'lib', $(BASEEXT) ]. The directories will be scanned and I<any> files
they contain will be installed in the corresponding location in the
library.  A libscan() method can be used to alter the behaviour.
Defining PM in the Makefile.PL will override PMLIBDIRS.

(Where BASEEXT is the last component of NAME.)
