# Determine shared object suffixes.

|
# Our method is to use the libtool variable $library_names_spec,
|
||
|
|
# set by using LT_INIT. This variable is a snippet of shell
|
||
|
|
# defined in terms of $versuffix, $release, $libname and $module
|
||
|
|
# We want to eval it and grab the suffix used for shared objects.
|
||
|
|
# By setting $module 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.
|
||
|
|
# Before calling this macro, libtool must have been configured.
|
||
|
|
|
||
|
|
# This macro is used internally to discover the suffix for the current
|
||
|
|
# settings of $module. The result is stored in $_SOSUFFIX.
