2073 dnl from a "native" curses implementation). If not installed for overwrite,
2074 dnl the curses.h file would be in an ncurses subdirectory (e.g.,
2075 dnl /usr/include/ncurses), but someone may have installed overwriting the
2076 dnl vendor's curses. Only very old versions (pre-1.9.2d, the first autoconf'd
2077 dnl version) of ncurses don't define either __NCURSES_H or NCURSES_VERSION in

2081 dnl is already in the include-path, don't even bother with this, since we cannot
2082 dnl easily determine which file it is. In this case, it has to be <curses.h>.
2084 dnl The optional parameter gives the root name of the library, in case it is

2690 dnl of C compiler options. This works around the problem that not all

2720 dnl Attempt to determine the appropriate CC/LD options for creating a shared
2723 dnl Note: ${LOCAL_LDFLAGS} is used to link executables that will run within the
2724 dnl build-tree, i.e., by making use of the libraries that are compiled in ../lib
2725 dnl We avoid compiling-in a ../lib path for the shared library since that can
2726 dnl lead to unexpected results at runtime.
2727 dnl ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared libraries
2728 dnl are compiled in ../../lib
2730 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
2731 dnl to install symbolic links to the rel/abi versions of shared libraries.
2733 dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
2734 dnl version when making symbolic links.
2736 dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
2737 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
2738 dnl (ex: libncurses.so.<ver>).
2740 dnl Some loaders leave 'so_locations' lying around. It's nice to clean up.
