37 ExtUtils::MM_Unix - methods used by ExtUtils::MakeMaker
41 C<require ExtUtils::MM_Unix;>
45 The methods provided by this package are designed to be used in
46 conjunction with ExtUtils::MakeMaker. When MakeMaker writes a
47 Makefile, it creates one or more objects that inherit their methods
48 from a package C<MM>. MM itself doesn't provide any methods, but it
49 ISA ExtUtils::MM_Unix class. The inheritance tree of MM lets operating
50 specific packages take the responsibility for all the methods provided
51 by MM_Unix. We are trying to reduce the number of the necessary
52 overrides by defining rather primitive operations within
55 If you are going to write a platform specific MM package, please try
56 to limit the necessary overrides to primitive methods, and if it is not
57 possible to do so, let's work out how to achieve that gain.
59 If you are overriding any of these methods in your Makefile.PL (in the
60 MY class), please report that to the makemaker mailing list. We are
61 trying to minimize the necessary method overrides and switch to data
62 driven Makefile.PLs wherever possible. In the long run less methods
63 will be overridable via the MY class.
67 The following description of methods is still under
68 development. Please refer to the code for not suitably documented
69 sections and complain loudly to the makemaker mailing list.
71 Not all of the methods below are overridable in a
72 Makefile.PL. Overridable methods are marked as (o). All methods are
73 overridable by a platform specific MM_*.pm file (See
74 L<ExtUtils::MM_VMS>) and L<ExtUtils::MM_OS2>).
78 # So we don't have to keep calling the methods over and over again,
79 # we have these globals to cache the values. They have to be global
80 # else the SelfLoaded methods can't see them.
