30 ExtUtils::MM_Unix - methods used by ExtUtils::MakeMaker
34 C<require ExtUtils::MM_Unix;>
38 The methods provided by this package are designed to be used in
39 conjunction with ExtUtils::MakeMaker. When MakeMaker writes a
40 Makefile, it creates one or more objects that inherit their methods
41 from a package C<MM>. MM itself doesn't provide any methods, but it
42 ISA ExtUtils::MM_Unix class. The inheritance tree of MM lets operating
43 specific packages take the responsibility for all the methods provided
44 by MM_Unix. We are trying to reduce the number of the necessary
45 overrides by defining rather primitive operations within
48 If you are going to write a platform specific MM package, please try
49 to limit the necessary overrides to primitive methods, and if it is not
50 possible to do so, let's work out how to achieve that gain.
52 If you are overriding any of these methods in your Makefile.PL (in the
53 MY class), please report that to the makemaker mailing list. We are
54 trying to minimize the necessary method overrides and switch to data
55 driven Makefile.PLs wherever possible. In the long run less methods
56 will be overridable via the MY class.
60 The following description of methods is still under
61 development. Please refer to the code for not suitably documented
62 sections and complain loudly to the makemaker mailing list.
64 Not all of the methods below are overridable in a
65 Makefile.PL. Overridable methods are marked as (o). All methods are
66 overridable by a platform specific MM_*.pm file (See
67 L<ExtUtils::MM_VMS>) and L<ExtUtils::MM_OS2>).
69 =head2 Preloaded methods
75 No physical check on the filesystem, but a logical cleanup of a
76 path. On UNIX eliminated successive slashes and successive "/.".
83 if ( $^O eq 'qnx' && $path =~ s|^(//\d+)/|/| ) {
86 $path =~ s|(?<=[^/])/+|/|g ; # xx////xx -> xx/xx
87 $path =~ s|(/\.)+/|/|g ; # xx/././xx -> xx/xx
88 $path =~ s|^(\./)+|| unless $path eq "./"; # ./xx -> xx
89 $path =~ s|(?<=[^/])/$|| ; # xx/ -> xx
95 Concatenate two or more directory names to form a complete path ending
96 with a directory. But remove the trailing slash from the resulting
97 string, because it doesn't look good, isn't necessary and confuses
98 OS2. Of course, if this is the root directory, don't cut off the
109 # append a slash to each argument unless it has one there
110 $_ .= "/" if $_ eq '' or substr($_,-1) ne "/";
112 $self->canonpath(join('', @args));
117 Concatenate one or more directory names and a filename to form a
118 complete path ending with a filename
125 return $self->canonpath($file) unless @_;
126 my $dir = $self->catdir(@_);
128 $_ .= "/" unless substr($_,length($_)-1,1) eq "/";
130 return $self->canonpath($dir.$file);
135 Returns a string representing of the current directory. "." on UNIX.
145 Returns a string representing of the root directory. "/" on UNIX.
155 Returns a string representing of the parent directory. ".." on UNIX.

1690 simply Configure (to include those extensions) and then build perl as
1691 normal. After installing perl the source tree can be deleted. It is
1692 not needed for building extensions by running 'perl Makefile.PL'
1693 usually without extra arguments.

1733 It is recommended that you install perl in a standard location before
