E.8 WIN32 Notes
===============

E.8.1 Getting the WIN32 version
-------------------------------

The latest version of the native Aspell/WIN32 port, including binaries,
can be found at `http://aspell.net/win32'. This page has,
unfortunately, not been updated for Aspell 0.60. If you are interested
in updated the native port please let me know.

E.8.2 Building the WIN32 version
--------------------------------

There are two basically different ways of building Aspell using GCC for
WIN32: You can either use the Cygwin compiler, which will produce
binaries that depend on the POSIX layer in `cygwin1.dll'. The other
way is using MinGW GCC, those binaries use the native C runtime from
Microsoft (MSVCRT.DLL).

E.8.2.1 Building Aspell using Cygwin
....................................

This works exactly like on other POSIX compatible systems using the
`./configure && make && make install' cycle. Some versions of Cygwin
GCC will fail to link, this is caused by an incorrect `libstdc++.la' in
the `/lib' directory. After removing or renaming this file, the build
progress should work (GCC-2.95 and GCC-3.x should work).

E.8.2.2 Building Aspell using MinGW
...................................

There are several different ways to build Aspell using MinGW. The
easiest way is to use a Cygwin compiler but instruct it to build a
native binary rather than a Cygwin one. To do this configure with:

./configure CFLAGS='-O2 -mno-cygwin' CXXFLAGS='-O2 -mno-cygswin'

You may also want to add the option `--enable-win32-relocatable' to
use more windows friendly directories. Win32-Directories. In
this case configure with:

./configure CFLAGS='-O2 -mno-cygwin' CXXFLAGS='-O2 -mno-cygswin' --enable-win32-relocatable

It should also be possible to build Aspell using the MSYS
environment. But this has not been very well tested. If building with
MSYS _do not_ add `CFLAGS ...' to configure.

E.8.2.3 Building Aspell without using Cygwin or MSYS
....................................................

It is also possible to build Aspell without Cygwin of MinGW by using
the files in the `win32/' subdirectory. However, these files have not
been updated to work with Aspell 0.60. Thus the following instructions
will not work without some effort. If you do get Aspell to compile
this way please send me the updated files so that I can include them
with the next release.

To compile Aspell with the MinGW compiler, you will need at least
GCC-3.2 (as shipped with MinGW-2.0.3) and some GNU tools like `rm' and
`cp'. The origin of those tools doesn't matter, it has shown to work
with any tools from MinGW/MSys, Cygwin or Linux. To build Aspell, move
into the `win32' subdirectory and type `make'. You can enable some
additional build options by either commenting out the definitions at
the head of the Makefile or passing those values as environment
variables or at the `make' command line. Following options are
supported:

`DEBUGVERSION'
If set to "1", the binaries will include debugging information
(resulting in a much bigger size).

`CURSESDIR'
Enter the path to the pdcurses library here, in order to get a
nicer console interface (see below).

`MSVCLIB'
Enter the filename of MS `lib.exe' here, if you want to build
libraries that can be imported from MS Visual C++.

`WIN32_RELOCATABLE'
If set to "1", Aspell will detect the prefix from the path where
the DLL resides (see below for further details).

`TARGET'
Sets a prefix to be used for cross compilation (e.g.
`/usr/local/bin/i586-mingw32msvc-' to cross compile from Linux).

There are also a MinGW compilers available for Cygwin and Linux, both
versions are able to compile Aspell using the prebuilt `Makefile'.
While the Cygwin port automatically detects the correct compiler, the
Linux version depends on setting the `TARGET' variable in the
`Makefile' (or environment) to the correct compiler prefix.

Other compilers may work. There is a patch for MS Visual C++ 6.0
available at `ftp://ftp.gnu.org/gnu/aspell', but it needs a lot of
changes to the Aspell sources. It has also been reported that the
Intel C++ compiler can be used for compilation.

E.8.3 (PD)Curses
----------------

In order to get the nice full screen interface when spell checking
files, a curses implementation that does not require Cygwin is
required. The PDCurses (`http://pdcurses.sourceforge.net')
implementation is known to work, other implementations may work however
they have not been tested. See the previous section for information on
specifying the location of the curses library and include file.

Curses notes:

* PDcurses built with MinGW needs to be compiled with
`-DPDC_STATIC_BUILD' to avoid duplicate declaration of `DllMain'
when compiling `aspell.exe'.

* The curses enabled version can cause trouble in some shells (MSys
`rxvt', `emacs') and will produce errors like `initscr() LINES=1
COLS=1: too small'. Use a non-curses version for those purposes.

E.8.4 Directories
-----------------

If Aspell is configured with `--enable-win32-relocatable' or compiled
with `WIN32_RELOCATABLE=1' when using a Makefile, it can be run from
any directory: it will set `PREFIX' according to its install location
(assuming it resides in `PREFIX\\bin'). Your personal wordlists will
be saved in the `PREFIX' directory with their names changed from
`.aspell.LANG.*' to `LANG.*' (you can override the path by setting the
`HOME' environment variable).

E.8.5 Installer
---------------

The installer registers the DLLs as shared libraries, you should
increase the reference counter to avoid the libraries being uninstalled
if your application still depends on them (and decrease it again when
uninstalling your program). The reference counters are located under:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDLLs

The install location and version numbers are stored under

HKLM\SOFTWARE\Aspell

E.8.6 WIN32 consoles
--------------------

The console uses a different encoding than GUI applications, changing
this to to a Windows encoding (e.g. 1252) is not supported on
Win9x/Me. On WinNT (and later) those codepages can be set by first
changing the console font to `lucida console', then changing the
codepage using `chcp 1252'.

Some alternative shells (e.g. MSys' `rxvt' or Cygwin's `bash') do a
codepage conversion (if correctly set up), so running Aspell inside
those shells might be a workaround for Win9x.
