<title>Installation of Ncurses</title>

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

<screen><userinput>./configure --prefix=/usr --with-shared --without-debug</userinput></screen>

<para>Compile the package:</para>

<screen><userinput>make</userinput></screen>

<para>This package does not come with a test suite.</para>

<para>Install the package:</para>

<screen><userinput>make install</userinput></screen>

<para>Give the Ncurses libraries execute permissions:</para>

<screen><userinput>chmod 755 /usr/lib/*.&ncurses-version;</userinput></screen>

<para>Fix a library that should not be executable:</para>

<screen><userinput>chmod 644 /usr/lib/libncurses++.a</userinput></screen>

<para>Move the libraries to the <filename class="directory">/lib</filename> directory,
where they are expected to reside:</para>

<screen><userinput>mv /usr/lib/libncurses.so.5* /lib</userinput></screen>

<para>Because the libraries have been moved, a few symlinks point to
non-existent files. Recreate those symlinks:</para>

<screen><userinput>ln -sf ../../lib/libncurses.so.5 /usr/lib/libncurses.so
ln -sf libncurses.so /usr/lib/libcurses.so</userinput></screen>
