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

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

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

107 <para>Move the shared libraries to the

109 expected to reside:</para>
110
111<screen><userinput remap="install">mv -v /usr/lib/libncursesw.so.6* /lib</userinput></screen>
112
113 <para>Because the libraries have been moved, one symlink points to
114 a non-existent file. Recreate it:</para>
115
116<screen><userinput remap="install">ln -sfv ../../lib/$(readlink /usr/lib/libncursesw.so) /usr/lib/libncursesw.so</userinput></screen>
117
118 <para>Many applications still expect the linker to be able to find
119 non-wide-character Ncurses libraries. Trick such applications into linking with
120 wide-character libraries by means of symlinks and linker scripts:</para>
121
122<screen><userinput remap="install">for lib in ncurses form panel menu ; do
123 rm -vf /usr/lib/lib${lib}.so
124 echo "INPUT(-l${lib}w)" &gt; /usr/lib/lib${lib}.so
125 ln -sfv ${lib}w.pc /usr/lib/pkgconfig/${lib}.pc
126done</userinput></screen>
127
128 <para>Finally, make sure that old applications that look for
129 <filename class="libraryfile">-lcurses</filename> at build time are still
130 buildable:</para>
131
132<screen><userinput remap="install">rm -vf /usr/lib/libcursesw.so
133echo "INPUT(-lncursesw)" &gt; /usr/lib/libcursesw.so
134ln -sfv libncurses.so /usr/lib/libcurses.so</userinput></screen>
135
136 <para>If desired, install the Ncurses documentation:</para>
137
138<screen><userinput remap="install">mkdir -v /usr/share/doc/ncurses-&ncurses-version;
139cp -v -R doc/* /usr/share/doc/ncurses-&ncurses-version;</userinput></screen>
140
141 <note>
142 <para>The instructions above don't create non-wide-character Ncurses
143 libraries since no package installed by compiling from sources would
144 link against them at runtime. However, the only known binary-only
145 applications that link against non-wide-character Ncurses libraries
146 require version 5. If you must have such libraries because
147 of some binary-only application or to be compliant with LSB, build
148 the package again with the following commands:</para>
149
150<screen role="nodump"><userinput>make distclean
151./configure --prefix=/usr \
152 --with-shared \
153 --without-normal \
