2719 dnl Attempt to determine the appropriate CC/LD options for creating a shared
2722 dnl Note: ${LOCAL_LDFLAGS} is used to link executables that will run within the
2723 dnl build-tree, i.e., by making use of the libraries that are compiled in ../lib
2724 dnl We avoid compiling-in a ../lib path for the shared library since that can
2725 dnl lead to unexpected results at runtime.
2726 dnl ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared libraries
2727 dnl are compiled in ../../lib
2729 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
2730 dnl to install symbolic links to the rel/abi versions of shared libraries.
2732 dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
2733 dnl version when making symbolic links.
2735 dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
2736 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
2737 dnl (ex: libncurses.so.<ver>).
2739 dnl Some loaders leave 'so_locations' lying around. It's nice to clean up.
