31 ExtUtils::MM_Unix - methods used by ExtUtils::MakeMaker
35 C<require ExtUtils::MM_Unix;>
39 The methods provided by this package are designed to be used in
40 conjunction with ExtUtils::MakeMaker. When MakeMaker writes a
41 Makefile, it creates one or more objects that inherit their methods
42 from a package C<MM>. MM itself doesn't provide any methods, but it
43 ISA ExtUtils::MM_Unix class. The inheritance tree of MM lets operating
44 specific packages take the responsibility for all the methods provided
45 by MM_Unix. We are trying to reduce the number of the necessary
46 overrides by defining rather primitive operations within
49 If you are going to write a platform specific MM package, please try
50 to limit the necessary overrides to primitive methods, and if it is not
51 possible to do so, let's work out how to achieve that gain.
53 If you are overriding any of these methods in your Makefile.PL (in the
54 MY class), please report that to the makemaker mailing list. We are
55 trying to minimize the necessary method overrides and switch to data
56 driven Makefile.PLs wherever possible. In the long run less methods
57 will be overridable via the MY class.
61 The following description of methods is still under
62 development. Please refer to the code for not suitably documented
63 sections and complain loudly to the makemaker mailing list.
65 Not all of the methods below are overridable in a
66 Makefile.PL. Overridable methods are marked as (o). All methods are
67 overridable by a platform specific MM_*.pm file (See
68 L<ExtUtils::MM_VMS>) and L<ExtUtils::MM_OS2>).
70 =head2 Preloaded methods
76 No physical check on the filesystem, but a logical cleanup of a
77 path. On UNIX eliminated successive slashes and successive "/.".
84 if ( $^O eq 'qnx' && $path =~ s|^(//\d+)/|/| ) {
87 $path =~ s|/+|/|g ; # xx////xx -> xx/xx
88 $path =~ s|(/\.)+/|/|g ; # xx/././xx -> xx/xx
89 $path =~ s|^(\./)+|| unless $path eq "./"; # ./xx -> xx
90 $path =~ s|/$|| unless $path eq "/"; # xx/ -> xx
96 Concatenate two or more directory names to form a complete path ending
97 with a directory. But remove the trailing slash from the resulting
98 string, because it doesn't look good, isn't necessary and confuses
99 OS2. Of course, if this is the root directory, don't cut off the
110 # append a slash to each argument unless it has one there
111 $_ .= "/" if $_ eq '' or substr($_,-1) ne "/";
113 $self->canonpath(join('', @args));
118 Concatenate one or more directory names and a filename to form a
119 complete path ending with a filename
126 return $self->canonpath($file) unless @_;
127 my $dir = $self->catdir(@_);
129 $_ .= "/" unless substr($_,length($_)-1,1) eq "/";
131 return $self->canonpath($dir.$file);
136 Returns a string representing of the current directory. "." on UNIX.
146 Returns a string representing of the root directory. "/" on UNIX.
156 Returns a string representing of the parent directory. ".." on UNIX.

1591 To rebuild extensions distributed with the perl source you should
1592 simply Configure (to include those extensions) and then build perl as
1593 normal. After installing perl the source tree can be deleted. It is
1594 not needed for building extensions by running 'perl Makefile.PL'
1595 usually without extra arguments.
1597 It is recommended that you unpack and build additional extensions away
