# NAME

ExtUtils::Mkbootstrap - make a bootstrap file for use by DynaLoader

# SYNOPSIS

`mkbootstrap`

# DESCRIPTION

Mkbootstrap typically gets called from an extension Makefile.

There is no `*.bs` file supplied with the extension. Instead a `*_BS` file which has code for the special cases, like posix for berkeley db on the NeXT.

This file will get parsed, and produce a maybe empty `@DynaLoader::dl_resolve_using` array for the current architecture. That will be extended by $BSLOADLIBS, which was computed by ExtUtils::Liblist::ext(). If this array still is empty, we do nothing, else we write a .bs file with an `@DynaLoader::dl_resolve_using` array.

The `*_BS` file can put some code into the generated `*.bs` file by placing it in `$bscode`. This is a handy 'escape' mechanism that may prove useful in complex situations.

If @DynaLoader::dl_resolve_using contains -L* or -l* entries then Mkbootstrap will automatically add a `dl_findfile()` call to the generated `*.bs` file.
