Instead, there may -be a C<*_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 -C<@DynaLoader::dl_resolve_using> array for the current architecture. -That will be extended by $BSLOADLIBS, which was computed by -ExtUtils::Liblist::ext(). If this array still is empty, we do nothing, -else we write a .bs file with an C<@DynaLoader::dl_resolve_using> -array. - -The C<*_BS> file can put some code into the generated C<*.bs> file by -placing it in C<$bscode>. This is a handy 'escape' mechanism that may -prove useful in complex situations. - -If @DynaLoader::dl_resolve_using contains C<-L*> or C<-l*> entries then -Mkbootstrap will automatically add a dl_findfile() call to the -generated C<*.bs> file. - -=cut |
