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

1765 To rebuild extensions distributed with the perl source you should
1766 simply Configure (to include those extensions) and then build perl as
1767 normal. After installing perl the source tree can be deleted. It is
1768 not needed for building extensions by running 'perl Makefile.PL'
1769 usually without extra arguments.
1771 It is recommended that you unpack and build additional extensions away
1772 from the perl source tree.

1810 It is recommended that you install perl in a standard location before
1811 building extensions. Some precompiled versions of perl do not contain
1812 these header files, so you cannot build extensions. In such a case,
1813 please build and install your perl from a fresh perl distribution. It
1814 usually solves this kind of problem.
