=head1 NAME
|
|
|
|
ExtUtils::Miniperl, writemain - write the C code for perlmain.c
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
C<use ExtUtils::Miniperl;>
|
|
|
|
C<writemain(@directories);>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This whole module is written when perl itself is built from a script
|
|
called minimod.PL. In case you want to patch it, please patch
|
|
minimod.PL in the perl distribution instead.
|
|
|
|
writemain() takes an argument list of directories containing archive
|
|
libraries that relate to perl modules and should be linked into a new
|
|
perl binary. It writes to STDOUT a corresponding perlmain.c file that
|
|
is a plain C file containing all the bootstrap code to make the
|
|
modules associated with the libraries available from within perl.
|
|
|
|
The typical usage is from within a Makefile generated by
|
|
ExtUtils::MakeMaker. So under normal circumstances you won't have to
|
|
deal with this module directly.
