NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

     mkbootstrap

DESCRIPTION    [Toc]    [Back]

     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.
