    <para>First, ensure that <command>gawk</command> is found first during configuration:</para>

<screen><userinput remap="pre">sed -i s/mawk// configure</userinput></screen>

    <para>Then, run the following commands to build the <quote>tic</quote>
    program on the build host:</para>

<screen><userinput remap="pre">mkdir build
pushd build
  ../configure
  make -C include
  make -C progs tic
popd</userinput></screen>

    <para>Prepare Ncurses for compilation:</para>

      <varlistentry>
        <term><parameter>--without-ada</parameter></term>
        <listitem>
          <para>This ensures that Ncurses does not build support for the Ada
          compiler which may be present on the host but will not be available
          once we enter the <command>chroot</command> environment.</para>
        </listitem>

      <varlistentry>
        <term><parameter>--enable-widec</parameter></term>
        <listitem>
          <para>This switch causes wide-character libraries (e.g., <filename
          class="libraryfile">libncursesw.so.&ncurses-version;</filename>)
          to be built instead of normal ones (e.g., <filename
          class="libraryfile">libncurses.so.&ncurses-version;</filename>).
          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>

      <varlistentry>
        <term><parameter>--enable-pc-files</parameter></term>

        <listitem>
          <para>This switch disables building the terminfo database: it is not
          needed at this stage, and if <command>tic</command> is too old,
          it cannot compile recent databases.</para>

<!-- TODO: check and document -->
<screen><userinput remap="install">make DESTDIR=$LFS TIC_PATH=$(pwd)/build/progs/tic install
ln -s libncursesw.so $LFS/usr/lib/libncurses.so</userinput></screen>

    <para>Move the shared libraries to the

    expected to reside:</para>

<screen><userinput remap="install">mv -v $LFS/usr/lib/libncursesw.so.6* $LFS/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 $LFS/usr/lib/libncursesw.so) $LFS/usr/lib/libncursesw.so</userinput></screen>
