55 ExtUtils::MM_Unix - methods used by ExtUtils::MakeMaker
59 C<require ExtUtils::MM_Unix;>
63 The methods provided by this package are designed to be used in
64 conjunction with ExtUtils::MakeMaker. When MakeMaker writes a
65 Makefile, it creates one or more objects that inherit their methods
66 from a package C<MM>. MM itself doesn't provide any methods, but it
67 ISA ExtUtils::MM_Unix class. The inheritance tree of MM lets operating
68 specific packages take the responsibility for all the methods provided
69 by MM_Unix. We are trying to reduce the number of the necessary
70 overrides by defining rather primitive operations within
73 If you are going to write a platform specific MM package, please try
74 to limit the necessary overrides to primitive methods, and if it is not
75 possible to do so, let's work out how to achieve that gain.
77 If you are overriding any of these methods in your Makefile.PL (in the
78 MY class), please report that to the makemaker mailing list. We are
79 trying to minimize the necessary method overrides and switch to data
80 driven Makefile.PLs wherever possible. In the long run less methods
81 will be overridable via the MY class.
85 The following description of methods is still under
86 development. Please refer to the code for not suitably documented
87 sections and complain loudly to the makemaker@perl.org mailing list.
88 Better yet, provide a patch.
90 Not all of the methods below are overridable in a
91 Makefile.PL. Overridable methods are marked as (o). All methods are
92 overridable by a platform specific MM_*.pm file.
94 Cross-platform methods are being moved into MM_Any. If you can't find
95 something that used to be in here, look in MM_Any.
99 # So we don't have to keep calling the methods over and over again,
100 # we have these globals to cache the values. Faster and shrtr.
