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, there may
be 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.
