| dnl ------------------- |
| dnl Look for the SVr4 curses clone 'ncurses' in the standard places, adjusting |
| dnl the CPPFLAGS variable so we can include its header. |
| dnl |
| dnl The header files may be installed as either curses.h, or ncurses.h (would |
| dnl be obsolete, except that some packagers prefer this name to distinguish it |
| dnl from a "native" curses implementation). If not installed for overwrite, |
| dnl the curses.h file would be in an ncurses subdirectory (e.g., |
| dnl /usr/include/ncurses), but someone may have installed overwriting the |
| dnl vendor's curses. Only very old versions (pre-1.9.2d, the first autoconf'd |
| dnl version) of ncurses don't define either __NCURSES_H or NCURSES_VERSION in |
| dnl the header. |
| dnl |
| dnl If the installer has set $CFLAGS or $CPPFLAGS so that the ncurses header |
| dnl is already in the include-path, don't even bother with this, since we cannot |
| dnl easily determine which file it is. In this case, it has to be <curses.h>. |
| dnl |
| dnl The optional parameter gives the root name of the library, in case it is |
| dnl not installed as the default curses library. That is how the |
| dnl wide-character version of ncurses is installed. |

| dnl --------------- |
| dnl Look for the ncurses library. This is a little complicated on Linux, |
| dnl because it may be linked with the gpm (general purpose mouse) library. |
| dnl Some distributions have gpm linked with (bsd) curses, which makes it |
| dnl unusable with ncurses. However, we don't want to link with gpm unless |
| dnl ncurses has a dependency, since gpm is normally set up as a shared library, |
| dnl and the linker will record a dependency. |
| dnl |
| dnl The optional parameter gives the root name of the library, in case it is |
| dnl not installed as the default curses library. That is how the |
| dnl wide-character version of ncurses is installed. |

| dnl CF_SHARED_OPTS version: 88 updated: 2015/08/05 20:44:28 |
| dnl -------------- |
| dnl -------------- |
| dnl Attempt to determine the appropriate CC/LD options for creating a shared |
| dnl library. |
| dnl |
| dnl Notes: |
| dnl a) ${LOCAL_LDFLAGS} is used to link executables that will run within |
| dnl the build-tree, i.e., by making use of the libraries that are compiled in |
| dnl $rel_builddir/lib We avoid compiling-in a $rel_builddir/lib path for the |
| dnl shared library since that can lead to unexpected results at runtime. |
| dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared |
| dnl libraries are compiled in ../../lib |
| dnl |
| dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure |
| dnl to install symbolic links to the rel/abi versions of shared libraries. |
| dnl |
| dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi |
| dnl version when making symbolic links. |
| dnl |
| dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library |
| dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix |
| dnl (ex: libncurses.so.<ver>). |
| dnl |
| dnl Some loaders leave 'so_locations' lying around. It's nice to clean up. |
