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