.SH NAME
ExtUtils::Mkbootstrap \- make a bootstrap file for use by DynaLoader
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& Mkbootstrap
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
Mkbootstrap typically gets called from an extension Makefile.
.PP
There is no \f(CW\*(C`*.bs\*(C'\fR file supplied with the extension. Instead, there may
be a \f(CW*_BS\fR file which has code for the special cases, like posix for
berkeley db on the NeXT.
.PP
This file will get parsed, and produce a maybe empty
\&\f(CW@DynaLoader::dl_resolve_using\fR array for the current architecture.
That will be extended by \f(CW$BSLOADLIBS\fR, which was computed by
\&\fBExtUtils::Liblist::ext()\fR. If this array still is empty, we do nothing,
else we write a .bs file with an \f(CW@DynaLoader::dl_resolve_using\fR
array.
.PP
The \f(CW*_BS\fR file can put some code into the generated \f(CW\*(C`*.bs\*(C'\fR file by
placing it in \f(CW$bscode\fR. This is a handy 'escape' mechanism that may
prove useful in complex situations.
.PP
If \f(CW@DynaLoader::dl_resolve_using\fR contains \f(CW\*(C`\-L*\*(C'\fR or \f(CW\*(C`\-l*\*(C'\fR entries then
Mkbootstrap will automatically add a \fBdl_findfile()\fR call to the
generated \f(CW\*(C`*.bs\*(C'\fR file.
