<h3 class="appendixsec">E.3 Curses Notes</h3>
<p>If you are having problems compiling <samp>check_funs.cpp</samp> then the
most likely reason is due to incompatibilities with the curses
implementation on your system. You should first try disabling the
“wide” curses library by with the <samp>--disable-wide-curses</samp>
configure option. By doing so you will lose support for properly
displaying UTF-8 characters but you may still be able to get the full
screen interface. If this fails than you can disable curses support
altogether with the <samp>--disable-curses</samp> configure option. By
doing this you will lose the nice full screen interface but hopefully
you will be able to at least get Aspell to compile correctly.
</p>
<p>If the curses library is installed in a non-standard location than you
can specify the library and include directory with
<samp>--enable-curses=<var>lib</var></samp> and
<samp>--enable-curses-include=<var>dir</var></samp>.
</p>
<p><samp><var>lib</var></samp> can either be the complete path of the library—for
example
</p><div class="example">
<pre class="example">/usr/local/curses/libcurses.a
</pre></div>
<p>or the name of the library (for example
<samp>ncurses</samp>) or a combined location and library in the form
<samp>-L<var>libdir</var> -l<var>lib</var></samp> (for example
<samp>-L/usr/local/ncurses/lib -lncurses</samp>).
</p>
<p><var>dir</var> is the location of the curses header files (for example
<samp>/usr/local/ncurses/include</samp>).
</p>
<a name="Unicode-Support"></a>
<h4 class="appendixsubsec">E.3.1 Unicode Support</h4>
<p>In order for Aspell to correctly spell check UTF-8 documents in full
screen mode the "wide" version of the curses library must be
installed. This is different from the normal version of curses
library, and is normally named <samp>libcursesw</samp> (with a ‘<samp>w</samp>’ at
the end) or <samp>libncursesw</samp>. UTF-8 documents will not display
correctly without the right curses version installed.
</p>
<p>In addition your system must also support the <code>mblen</code> function.
Although this function was defined in the ISO C89 standard (ANSI
X3.159-1989), not all systems have it.
