extutils::mkbootstrap(3)
NAME
ExtUtils::Mkbootstrap - make a bootstrap file for use by
DynaLoader
SYNOPSIS
"Mkbootstrap"
DESCRIPTION
Mkbootstrap typically gets called from an extension Make
file.
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 archi
tecture. 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_find_ file() call to the generated "*.bs" file.
