# $Id: sosuffix.ac,v 1.1 2002/07/08 13:15:05 dda Exp $# Determine shared object suffixes.## Our method is to use the libtool variable $library_names_spec,# set by using AC_PROG_LIBTOOL.  This variable is a snippet of shell# defined in terms of $versuffix, $release, $libname, $module and $jnimodule.# We want to eval it and grab the suffix used for shared objects.# By setting $module and $jnimodule to yes/no, we obtain the suffixes# used to create dlloadable, or java loadable modules.# On many (*nix) systems, these all evaluate to .so, but there# are some notable exceptions.# This macro is used internally to discover the suffix for the current# settings of $module and $jnimodule.
