32 ExtUtils::MM_Unix - methods used by ExtUtils::MakeMaker
36 C<require ExtUtils::MM_Unix;>
40 The methods provided by this package are designed to be used in
41 conjunction with ExtUtils::MakeMaker. When MakeMaker writes a
42 Makefile, it creates one or more objects that inherit their methods
43 from a package C<MM>. MM itself doesn't provide any methods, but it
44 ISA ExtUtils::MM_Unix class. The inheritance tree of MM lets operating
45 specific packages take the responsibility for all the methods provided
46 by MM_Unix. We are trying to reduce the number of the necessary
47 overrides by defining rather primitive operations within
50 If you are going to write a platform specific MM package, please try
51 to limit the necessary overrides to primitive methods, and if it is not
52 possible to do so, let's work out how to achieve that gain.
54 If you are overriding any of these methods in your Makefile.PL (in the
55 MY class), please report that to the makemaker mailing list. We are
56 trying to minimize the necessary method overrides and switch to data
57 driven Makefile.PLs wherever possible. In the long run less methods
58 will be overridable via the MY class.
62 The following description of methods is still under
63 development. Please refer to the code for not suitably documented
64 sections and complain loudly to the makemaker mailing list.
66 Not all of the methods below are overridable in a
67 Makefile.PL. Overridable methods are marked as (o). All methods are
68 overridable by a platform specific MM_*.pm file (See
69 L<ExtUtils::MM_VMS>) and L<ExtUtils::MM_OS2>).
71 =head2 Preloaded methods
77 No physical check on the filesystem, but a logical cleanup of a
78 path. On UNIX eliminated successive slashes and successive "/.".
85 if ( $^O eq 'qnx' && $path =~ s|^(//\d+)/|/|s ) {
88 $path =~ s|(?<=[^/])/+|/|g ; # xx////xx -> xx/xx
89 $path =~ s|(/\.)+/|/|g ; # xx/././xx -> xx/xx
90 $path =~ s|^(\./)+||s unless $path eq "./"; # ./xx -> xx
91 $path =~ s|(?<=[^/])/\z|| ; # xx/ -> xx
97 Concatenate two or more directory names to form a complete path ending
98 with a directory. But remove the trailing slash from the resulting
99 string, because it doesn't look good, isn't necessary and confuses
100 OS2. Of course, if this is the root directory, don't cut off the
111 # append a slash to each argument unless it has one there
112 $_ .= "/" if $_ eq '' or substr($_,-1) ne "/";
114 $self->canonpath(join('', @args));
119 Concatenate one or more directory names and a filename to form a
120 complete path ending with a filename
127 return $self->canonpath($file) unless @_;
128 my $dir = $self->catdir(@_);
130 $_ .= "/" unless substr($_,length($_)-1,1) eq "/";
132 return $self->canonpath($dir.$file);
137 Returns a string representing of the current directory. "." on UNIX.
147 Returns a string representing of the root directory. "/" on UNIX.
157 Returns a string representing of the parent directory. ".." on UNIX.

1711 simply Configure (to include those extensions) and then build perl as

1713 not needed for building extensions by running 'perl Makefile.PL'
1714 usually without extra arguments.

3842 is one-pass, and Perl includes some overrides for C RTL functions,

3854 This is internal method that returns name of a file that is
