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