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 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.

DISCLAIMER

We are painfully aware that these documents may contain incorrect links and misformatted HTML. Such bugs lie in the automatic translation process that automatically created the hundreds and hundreds of separate documents that you find here. Please do not report link or formatting bugs, because we cannot fix per-document problems. The only bug reports that will help us are those that supply working patches to the installhtml or pod2html programs, or to the Pod::HTML module itself, for which I and the entire Perl community will shower you with thanks and praises.

If rather than formatting bugs, you encounter substantive content errors in these documents, such as mistakes in the explanations or code, please use the perlbug utility included with the Perl distribution.
