131 .IX Title "ExtUtils::Mkbootstrap 3"
132 .TH ExtUtils::Mkbootstrap 3 "2009-07-07" "perl v5.8.7" "User Contributed Perl Documentation"
134 ExtUtils::Mkbootstrap \- make a bootstrap file for use by DynaLoader
136 .IX Header "SYNOPSIS"
137 \&\f(CW\*(C`Mkbootstrap\*(C'\fR
139 .IX Header "DESCRIPTION"
140 Mkbootstrap typically gets called from an extension Makefile.
142 There is no \f(CW\*(C`*.bs\*(C'\fR file supplied with the extension. Instead, there may
143 be a \f(CW*_BS\fR file which has code for the special cases, like posix for
144 berkeley db on the NeXT.
146 This file will get parsed, and produce a maybe empty
147 \&\f(CW@DynaLoader::dl_resolve_using\fR array for the current architecture.
148 That will be extended by \f(CW$BSLOADLIBS\fR, which was computed by
149 \&\fIExtUtils::Liblist::ext()\fR. If this array still is empty, we do nothing,
150 else we write a .bs file with an \f(CW@DynaLoader::dl_resolve_using\fR
153 The \f(CW*_BS\fR file can put some code into the generated \f(CW\*(C`*.bs\*(C'\fR file by
154 placing it in \f(CW$bscode\fR. This is a handy 'escape' mechanism that may
155 prove useful in complex situations.
157 If \f(CW@DynaLoader::dl_resolve_using\fR contains \f(CW\*(C`\-L*\*(C'\fR or \f(CW\*(C`\-l*\*(C'\fR entries then
158 Mkbootstrap will automatically add a \fIdl_findfile()\fR call to the
159 generated \f(CW\*(C`*.bs\*(C'\fR file.
