An EUMM version based on an app I wrote that generates a makefile with a
custom 'make install' target line.
I'll keep out of the MI / MB holy wars, this needed to work in a specific
environment with an old perl setup.
use ExtUtils::MakeMaker;
use ExtUtils::Manifest;
use ExtUtils::Install;
my @make_paths = qw( ... );
my @copy_files = qw( ... );
WriteMakefile(
...
);
package MY;
sub postamble {
my $s = <<'EOM';
my_make ::
# examples of how you could use a script or separate makefile to do the
install
@${PERL} -I$(INST_LIB) bin/my_deploy.pl
\$(MAKE) -f Makefile.my
my_install ::
some commands here
EOM
# add create dir command lines to the my_install target
for my $path (@make_paths) {
$s .= "\t\$(MKPATH) \$(C_APPDIR)/$path\n";
}
# add copy file command lines to the my_install target
for my $path (@copy_files) {
$s .= "\t\$(CP) $path \$(C_APPDIR)/$path\n";
}
return $s;
}
# add dependency my_install to target install, to call postamble target
sub install {
my $class = shift;
my $basic = $class->SUPER::install(@_);
$basic =~ s/^(install :: .*)$/$1 my_install/m;
return $basic;
}
sub my_config_vars {
return {
C_APPDIR => '/some/path/',
};
};
# add variables for use in postamble my_install target
sub constants {
my $class = shift;
my $basic = $class->SUPER::constants(@_);
my $vars = $my_config_vars;
my @prepend = map { "$_ = $vars->{$_}" } sort keys %$vars;
return join("\n",@prepend) . "\n" . $basic;
}
