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.</para>

<para>Compile the package:</para>

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

</para>
|

<para>Install the package:</para>

<screen><userinput remap="install">make install</userinput></screen>
|
|
|
|
<para>Move the shared libraries to the
|
|
<filename class="directory">/lib</filename> directory, where they are
|
|
expected to reside:</para>
|
|
|
|
<screen><userinput remap="install">mv -v /usr/lib/libncursesw.so.6* /lib</userinput></screen>
|
|
|
|
<para>Because the libraries have been moved, one symlink points to
|
|
a non-existent file. Recreate it:</para>
|
|
|
|
<screen><userinput remap="install">ln -sfv ../../lib/$(readlink /usr/lib/libncursesw.so) /usr/lib/libncursesw.so</userinput></screen>
|
|
|
|
<para>Many applications still expect the linker to be able to find
|
|
non-wide-character Ncurses libraries. Trick such applications into linking with
|
|
wide-character libraries by means of symlinks and linker scripts:</para>
|
|
|
|
<screen><userinput remap="install">for lib in ncurses form panel menu ; do
|
|
rm -vf /usr/lib/lib${lib}.so
|
|
echo "INPUT(-l${lib}w)" > /usr/lib/lib${lib}.so
|
|
ln -sfv ${lib}w.pc /usr/lib/pkgconfig/${lib}.pc
|
|
done</userinput></screen>
|
|
|
|
<para>Finally, make sure that old applications that look for
|
|
<filename class="libraryfile">-lcurses</filename> at build time are still
|
|
buildable:</para>
|
|
|
|
<screen><userinput remap="install">rm -vf /usr/lib/libcursesw.so
|
|
echo "INPUT(-lncursesw)" > /usr/lib/libcursesw.so
|
|
ln -sfv libncurses.so /usr/lib/libcurses.so</userinput></screen>
|
|
|
|
<para>If desired, install the Ncurses documentation:</para>
|
|
|
|
<screen><userinput remap="install">mkdir -v /usr/share/doc/ncurses-&ncurses-version;
|
|
cp -v -R doc/* /usr/share/doc/ncurses-&ncurses-version;</userinput></screen>
|
|
|
|
<note>
|
|
|
|
<para>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. Currently, the only known binary-only
|
|
applications that link against non-wide-character Ncurses require version
|
|
5. 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:</para>
|
|
|
|
<screen role="nodump"><userinput>make distclean
|
|
./configure --prefix=/usr \
|
|
--with-shared \
|
|
--without-normal \
|
|
--without-debug \
|
|
--without-cxx-binding \
|
|

|

make sources libs
