The port was made much easier by the groundbreaking work of Geoff Voelker
and others who worked on the GNU Emacs port to NT. Their version is available
from http://www.cs.washington.edu/homes/voelker/ntemacs.html

To get it working you will need:

1.  You will need Visual C++ V4.0 or later to compile everything. Personally we
    have tested V4.0, V4.2 and V5.0.
    Note that Visual C++ assumes a couple of environment variables INCLUDE and
    LIB to be set which specify the location of the includes and libraries.
    Your PATH environment variable also needs to include the DevStudio vc\bin
    and sharedide\bin directories.
    Visual C++ V5.0 installs a batch file called vcvars32.bat in
    c:\Program Files\DevStudio\VC\bin\ (or wherever you installed it) that you
    can run before building to set up all of these environment variables.

2.  Grab the latest XEmacs source from ftp.xemacs.org if necessary. All Win32
    support is in the nt\ subdirectory. You'll also need the xemacs-base
    package from the binary-packages subdirectory and you'll probably also
    want at least the edit-utils, text-modes, fsf-compat, cc-mode,
    prog-modes and xemacs-devel packages.
    Unpack the packages into, say, "c:\Program Files\XEmacs\xemacs-packages".

3.  At this point you can select X or Win32 native GUI support.

If you want to build for native GUI:

1.  If you want XPM image and toolbar support grab the latest version of the
    xpm sources (xpm-3.4k.tar.gz at time of writing) and unpack them somewhere.
    Copy nt\xpm.mak from the xemacs sources to the lib subdirectory of the
    xpm sources, cd to that directory and build xpm with 'nmake -f xpm.mak'.

2.  You probably also want PNG image support. Grab the latest versions of zlib
    and libpng (zlib-1.1.3 and libpng-1.0.2 at time of writing), unpack them
    somewhere and read the respective READMEs for details on how to build them.
    The following build procedure works for zlib-1.1.3 and libpng-1.0.2:

    cd to the zlib directory, type 'copy msdos\makefile.w32 Makefile' and
    then type 'nmake'.

    cd to the libpng directory, rename or move the zlib directory to ..\zlib
    and type 'nmake -f scripts\makefile.w32'.

3.  If you want TIFF support, grap the latest version of libtiff (tiff-v3.4
    at time of writing) and unpack it somewhere. Copy nt\tiff.mak from the 
    xemacs sources to the contrib\winnt subdirectory of the tiff sources, 
    cd to that directory and build libtiff with 'nmake -f tiff.mak'. Note:
    tiff.mak has only been verified to work under WinNT, not Win95 or 98. 
    However, the lastest distribution of libtiff includes a 
    contrib\win95\makefile.w95; that might work.

4.  If you want JPEG support grab the latest version of jpegsrc (jpeg-6b at 
    time of writing) and read the README for details on how to build it.

5.  cd to the nt subdirectory of the xemacs distribution and build xemacs:
    `nmake install -f xemacs.mak` or `nmake install -f xemacs95.mak`
     under windows 95 and windows 98, but read on before hitting Enter.

6.  If you're building with XPM support, add this to the nmake command line:
	HAVE_XPM=1 XPM_DIR="x:\location\of\your\xpm\sources"
    and similarly for JPEG and TIFF support.

    If you're building with PNG support, add this to the nmake command line:
	HAVE_PNG=1 PNG_DIR="x:\location\of\your\png\sources"
	ZLIB_DIR="x:\location\of\your\zlib\sources"

    If you want to build with GIF support, add this to the nmake command line:
	HAVE_GIF=1

7.  By default, XEmacs will expect to find its packages in the subdirectories
    "site-packages", "mule-packages" and "xemacs-packages" under the package
    prefix directory "c:\Program Files\XEmacs". If you want it to look for
    these subdirectories elsewhere, add this to the nmake command line:
	PACKAGE_PREFIX="x:\your\package\directory"
    If you change your mind and want to alter the package prefix directory
    after you've built XEmacs, delete the file .\obj\emacs.obj and rebuild with
    the new PACKAGE_PREFIX.

8.  By default, XEmacs will be installed in directories under the directory
    "c:\Program Files\XEmacs\XEmacs-21.0". If you want to install it elsewhere,
    add this to the nmake command line:
	INSTALL_DIR="x:\your\installation\directory"

9.  Now you can press Enter. nmake will build temacs, the DOC file, update the
    elc's, dump xemacs and install the relevant files in the directories under
    the installation directory. Unless you set INSTALL_DIR above, the file that
    you should run to start XEmacs will be installed as 
    "c:\Program Files\XEmacs\XEmacs-21.0\i386-pc-win32\runemacs.exe". You may
    want to create a shortcut to that file from your Desktop or Start Menu.

10. The build process always creates debugging and "Source Browser" information
    in the source tree for use with MS DevStudio. If you actually want to debug
    XEmacs you should run XEmacs from the source directory instead of from the
    installation directory. You should probably also build a debug version of
    XEmacs; to do this start with a clean source tree and add DEBUG_XEMACS=1 to
    the nmake command line. You probably don't want to install your debug build
    so you should tell nmake to build the 'all' target instead of the 'install'
    target.

    To make use of the debugging and "Source Browser" information, create a new
    "console" project in MS DevStudio and, under Project/Settings, set:
	Debug: executable name = full path of src\xemacs.exe
	Link: output file name = full path of src\temacs.exe
	Browse Info: browse info file name = full path of src\temacs.bsc
    Remember to close the Source Browser file in DevStudio before rebuilding.


If you want support for X you will need:

1.  An X server. MI/X is available on the Internet for free; It is 
    available from:  http://www.microimages.com/www/html/freestuf/mixdlfrm.htm

2.  The MIT X11R6.3 libraries available from: ftp.x.org

3.  You'll need to compile the MIT libraries without multi-thread support.
    To do this, there is an example Win32.cf and site.def provided which
    set the relevant flags. You will also need to apply the patch in 
    nt/X11.patch in the xc/lib/X11 directory which will fix the DLL definition
    file. Once compiled and installed, you will need to apply the following
    patch to Xmd.h. This is messy and better solutions would be appreciated. 

4.  Goto 2 under 'native GUI' above and add this to the nmake command line:
	HAVE_X=1 X11_DIR=x:\root\directory\of\your\X11\installation
