E.3 Curses Notes
================
If you are having problems compiling `check_funs.cpp' 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 `--disable-wide-curses' 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 `--disable-curses' 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.
If the curses library is installed in a non-standard location than
you can specify the library and include directory with
`--enable-curses=LIB' and `--enable-curses-include=DIR'.
`LIB' can either be the complete path of the library--for example
/usr/local/curses/libcurses.a
or the name of the library (for example `ncurses') or a combined
location and library in the form `-LLIBDIR -lLIB' (for example
`-L/usr/local/ncurses/lib -lncurses').
DIR is the location of the curses header files (for example
`/usr/local/ncurses/include').
E.3.1 Unicode Support
---------------------
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 `libcursesw' (with a `w' at the end) or `libncursesw'.
UTF-8 documents will not display correctly without the right curses
version installed.
In addition your system must also support the `mblen' function.
Although this function was defined in the ISO C89 standard (ANSI
X3.159-1989), not all systems have it.
