Description
"ModPerl::MM" is a ``subclass'' of "ExtUtils::MakeMaker" for mod_perl 2.0, to a degree of sub-classability of "ExtUtils::MakeMaker".When "ModPerl::MM::WriteMakefile()" is used instead of "ExtUtils::MakeMaker::WriteMakefile()", "ModPerl::MM" overrides several "ExtUtils::MakeMaker" methods behind the scenes and supplies default "WriteMakefile()" arguments adjusted for mod_perl 2.0 build. It's written in such a way so that normally 3rd party module developers for mod_perl 2.0, don't need to mess with Makefile.PL at all.
MY:: Default Methods
"ModPerl::MM" overrides method foo as long as Makefile.PL hasn't already specified a method MY::foo. If the latter happens, "ModPerl::MM" will DWIM and do nothing.In case the functionality of "ModPerl::MM" methods needs to be extended, rather than completely overridden, the "ModPerl::MM" methods can be called internally. For example if you need to modify constants in addition to the modifications applied by "ModPerl::MM::MY::constants", call the "ModPerl::MM::MY::constants" method (notice that it resides in the package "ModPerl::MM::MY" and not "ModPerl::MM"), then do your extra manipulations on constants:
# if there is a need to extend the methods sub MY::constants { my $self = shift; $self->ModPerl::MM::MY::constants; # do something else; }
In certain cases a developers may want to prevent from "ModPerl::MM" to override certain methods. In that case an explicit override in Makefile.PL will do the job. For example if you don't want the "constants()" method to be overridden by "ModPerl::MM", add to your Makefile.PL:
sub MY::constants { shift->MM::constants(@_); }";
"ModPerl::MM" overrides the following methods:
ModPerl::MM::MY::post_initialize
This method is deprecated.WriteMakefile() Default Arguments
"ModPerl::MM::WriteMakefile" supplies default arguments such as "INC" and "TYPEMAPS" unless they weren't passed to "ModPerl::MM::WriteMakefile" from Makefile.PL.If the default values aren't satisfying these should be overridden in Makefile.PL. For example to supply an empty INC, explicitly set the argument in Makefile.PL.
ModPerl::MM::WriteMakefile( ... INC => '', ... );
If instead of fully overriding the default arguments, you want to extend or modify them, they can be retrieved using the "ModPerl::MM::get_def_opt()" function. The following example appends an extra value to the default "INC" attribute:
my $extra_inc = "/foo/include"; ModPerl::MM::WriteMakefile( ... INC => join " ", $extra_inc, ModPerl::MM::get_def_opt('INC'), ... );
"ModPerl::MM" supplies default values for the following "ModPerl::MM::WriteMakefile" attributes:
CCFLAGS
LIBS
INC
OPTIMIZE
LDDLFLAGS
TYPEMAPS
dynamic_lib
"OTHERLDFLAGS"
dynamic_lib => { OTHERLDFLAGS => ... }
macro
"MOD_INSTALL"
macro => { MOD_INSTALL => ... }
makes sure that Apache-Test/ is added to @INC.
