69 <para>This switch causes wide-character libraries (e.g., <filename
70 class="libraryfile">libncursesw.so.&ncurses-version;</filename>)
71 to be built instead of normal ones (e.g., <filename
72 class="libraryfile">libncurses.so.&ncurses-version;</filename>).
73 These wide-character libraries are usable in both multibyte and
74 traditional 8-bit locales, while normal libraries work properly
75 only in 8-bit locales. Wide-character and normal libraries are
76 source-compatible, but not binary-compatible.</para>

101
102 <para>This package has a test suite, but it can only be run after the
103 package has been installed. The tests reside in the
104 <filename class="directory">test/</filename> directory. See the
105 <filename>README</filename> file in that directory for further details.

108 <para>Install the package:</para>

110<screen><userinput remap="install">make install</userinput></screen>
111
112 <para>Move the shared libraries to the
113 <filename class="directory">/lib</filename> directory, where they are
114 expected to reside:</para>
115
116<screen><userinput remap="install">mv -v /usr/lib/libncursesw.so.5* /lib</userinput></screen>
117
118 <para>Because the libraries have been moved, one symlink points to
119 a non-existent file. Recreate it:</para>
120
121<screen><userinput remap="install">ln -sfv ../../lib/$(readlink /usr/lib/libncursesw.so) /usr/lib/libncursesw.so</userinput></screen>
122
123 <para>Many applications still expect the linker to be able to find
124 non-wide-character Ncurses libraries. Trick such applications into linking with
125 wide-character libraries by means of symlinks and linker scripts:</para>
126
127<screen><userinput remap="install">for lib in ncurses form panel menu ; do
128 rm -vf /usr/lib/lib${lib}.so
129 echo "INPUT(-l${lib}w)" &gt; /usr/lib/lib${lib}.so
130 ln -sfv ${lib}w.pc /usr/lib/pkgconfig/${lib}.pc
131done</userinput></screen>
132
133 <para>Finally, make sure that old applications that look for
134 <filename class="libraryfile">-lcurses</filename> at build time are still
135 buildable:</para>
136
137<screen><userinput remap="install">rm -vf /usr/lib/libcursesw.so
138echo "INPUT(-lncursesw)" &gt; /usr/lib/libcursesw.so
139ln -sfv libncurses.so /usr/lib/libcurses.so</userinput></screen>
140
141 <para>If desired, install the Ncurses documentation:</para>
142
143<screen><userinput remap="install">mkdir -v /usr/share/doc/ncurses-&ncurses-version;
144cp -v -R doc/* /usr/share/doc/ncurses-&ncurses-version;</userinput></screen>
145
146 <note>
147 <para>The instructions above don't create non-wide-character Ncurses
148 libraries since no package installed by compiling from sources would
149 link against them at runtime. If you must have such libraries because
150 of some binary-only application or to be compliant with LSB, build
151 the package again with the following commands:</para>
152
153<screen role="nodump"><userinput>make distclean
154./configure --prefix=/usr \
155 --with-shared \
