6.19. Ncurses-5.7

The Ncurses package contains libraries for terminal-independent handling of character screens.

Approximate build time: 0.8 SBU
Required disk space: 35 MB

6.19.1. Installation of Ncurses

Prepare Ncurses for compilation:

./configure --prefix=/usr --with-shared --without-debug --enable-widec

The meaning of the configure option:


This switch causes wide-character libraries (e.g., libncursesw.so.5.7) to be built instead of normal ones (e.g., libncurses.so.5.7). These wide-character libraries are usable in both multibyte and traditional 8-bit locales, while normal libraries work properly only in 8-bit locales. Wide-character and normal libraries are source-compatible, but not binary-compatible.

Compile the package:


This package has a test suite, but it can only be run after the package has been installed. The tests reside in the test/ directory. See the README file in that directory for further details.

Install the package:

make install

Move the shared libraries to the /lib directory, where they are expected to reside:

mv -v /usr/lib/libncursesw.so.5* /lib

Because the libraries have been moved, one symlink points to a non-existent file. Recreate it:

ln -sfv ../../lib/libncursesw.so.5 /usr/lib/libncursesw.so

Many applications still expect the linker to be able to find non-wide-character Ncurses libraries. Trick such applications into linking with wide-character libraries by means of symlinks and linker scripts:

for lib in ncurses form panel menu ; do \
    rm -vf /usr/lib/lib${lib}.so ; \
    echo "INPUT(-l${lib}w)" >/usr/lib/lib${lib}.so ; \
    ln -sfv lib${lib}w.a /usr/lib/lib${lib}.a ; \
ln -sfv libncurses++w.a /usr/lib/libncurses++.a

Finally, make sure that old applications that look for -lcurses at build time are still buildable:

rm -vf /usr/lib/libcursesw.so
echo "INPUT(-lncursesw)" >/usr/lib/libcursesw.so
ln -sfv libncurses.so /usr/lib/libcurses.so
ln -sfv libncursesw.a /usr/lib/libcursesw.a
ln -sfv libncurses.a /usr/lib/libcurses.a

If desired, install the Ncurses documentation:

mkdir -v       /usr/share/doc/ncurses-5.7
cp -v -R doc/* /usr/share/doc/ncurses-5.7


The instructions above don't create non-wide-character Ncurses libraries since no package installed by compiling from sources would link against them at runtime. If you must have such libraries because of some binary-only application or to be compliant with LSB, build the package again with the following commands:

make distclean
./configure --prefix=/usr --with-shared --without-normal \
  --without-debug --without-cxx-binding
make sources libs
cp -av lib/lib*.so.5* /usr/lib

6.19.2. Contents of Ncurses

Installed programs: captoinfo (link to tic), clear, infocmp, infotocap (link to tic), ncursesw5-config, reset (link to tset), tic, toe, tput, and tset
Installed libraries: libcursesw.{a,so} (symlink and linker script to libncursesw.{a,so}), libformw.{a,so}, libmenuw.{a,so}, libncurses++w.a, libncursesw.{a,so}, libpanelw.{a,so} and their non-wide-character counterparts without "w" in the library names.
Installed directories: /usr/share/tabset, /usr/share/terminfo

Short Descriptions


Converts a termcap description into a terminfo description


Clears the screen, if possible


Compares or prints out terminfo descriptions


Converts a terminfo description into a termcap description


Provides configuration information for ncurses


Reinitializes a terminal to its default values


The terminfo entry-description compiler that translates a terminfo file from source format into the binary format needed for the ncurses library routines. A terminfo file contains information on the capabilities of a certain terminal


Lists all available terminal types, giving the primary name and description for each


Makes the values of terminal-dependent capabilities available to the shell; it can also be used to reset or initialize a terminal or report its long name


Can be used to initialize terminals


A link to libncurses


Contains functions to display text in many complex ways on a terminal screen; a good example of the use of these functions is the menu displayed during the kernel's make menuconfig


Contains functions to implement forms


Contains functions to implement menus


Contains functions to implement panels
