ExtUtils::Mkbootstrap - make a bootstrap file for use by DynaLoader
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
. 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()
the generated "*.bs" file.
