3684 dnl --------------
3685 dnl --------------
3686 dnl Attempt to determine the appropriate CC/LD options for creating a shared
3687 dnl library.
3688 dnl
3689 dnl Note: ${LOCAL_LDFLAGS} is used to link executables that will run within the
3690 dnl build-tree, i.e., by making use of the libraries that are compiled in ../lib
3691 dnl We avoid compiling-in a ../lib path for the shared library since that can
3692 dnl lead to unexpected results at runtime.
3693 dnl ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared libraries
3694 dnl are compiled in ../../lib
3695 dnl
3696 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
3697 dnl to install symbolic links to the rel/abi versions of shared libraries.
3698 dnl
3699 dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
3700 dnl version when making symbolic links.
3701 dnl
3702 dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
3703 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
3704 dnl (ex: libncurses.so.<ver>).
3705 dnl
3706 dnl Some loaders leave 'so_locations' lying around.  It's nice to clean up.
