This is a port of XEmacs to Windows 95/98/ME/NT/2000/XP.  If you are
looking for a port of GNU Emacs, get the latest release of the 21.x series
from gnu.org.  NT 4.0 or later is required for building on Windows NT.
Note that the developers typically use NT 4.0 and Windows 2000 or XP, and
there may possibly be problems under Windows 95/98. (One developer has
successfully built on Windows ME, though, which is the successor of Windows
98.)  If so, please report them to xemacs-nt@xemacs.org; we are committed
to maintaining compatibility with all systems listed.

* Required tools and sources
============================

1.  You will need Visual C++ V6.0, Visual Studio .NET or later to compile
    everything.

    Note that Visual C++ assumes that the environment variables INCLUDE and
    LIB are set to specify the location of the includes and libraries.
    Your PATH environment variable also needs to include the Visual Studio
    vc\bin and sharedide\bin directories.

    Visual C++ V6.0 installs a batch file called vcvars32.bat in
    c:\Program Files\Microsoft Visual Studio\VC98\bin\ (or wherever you
    installed it) that you can run before building to set up all of these
    environment variables.  Alternatively, you can choose at setup time to
    have these environment variables automatically set up in the registry,
    which is generally a good idea.

    Visual Studio .NET calls this batch file vsvars32.bat and installs it in
    $Installdir\Common7\Tools, but doesn't offer at install time to
    automatically set these environment variables up in the registry.

2.  Grab the latest XEmacs source from

      http://ftp.xemacs.org/pub/xemacs/

    or one of its mirrors listed at http://www.xemacs.org/Download/index.html.

    (NOTE: If you are behind a firewall and have problems with FTP access,
    the URL http://ftp.xemacs.org/pub/xemacs/ works just as well.)

    You'll also need the packages.  You probably want to get the unified
    packages bundle from

      http://ftp.xemacs.org/pub/xemacs/packages/xemacs-sumo.tar.gz

    If you are building with international support, you also need

      http://ftp.xemacs.org/pub/xemacs/packages/xemacs-mule-sumo.tar.gz

    Although we don't recommend it, you can also retrieve just the packages
    you really need if you have an extremely slow net connection or are very
    short on disk space.  You can find the various packages in
    http://ftp.xemacs.org/pub/xemacs/packages/.  You will need the xemacs-base
    package (and mule-base, if building with international support).  You'll
    also need the texinfo package unless you have a copy of makeinfo.exe on
    your machine.  If you want to download additional or updated packages
    from within XEmacs you'll need the efs, dired and vm packages.  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 "x:\your\choice\XEmacs\xemacs-packages",
    for example "c:\Program Files\XEmacs\xemacs-packages".

3.  The native build no longer supports X Windows.  There is no point,
    since the Cygwin build is actively maintained and supports X Windows
    very well.  See the FAQ if you want to build with Cygwin.


* Optional libraries
====================

The easiest way to get the optional libraries is to grab the appropriate
set of precompiled versions for your compiler:

http://www.xemacs.org/Download/win32/optional-libs.exe

or for VC++ 2005 (VC8)

http://www.xemacs.org/Download/win32/optional-libs-vc8.exe

unpack them somewhere and set the OPTIONAL_LIBRARY_DIR in config.inc
to point to where you put them.  This will automatically give you
all the graphics libraries. (NOTE: optional-libs.exe was compiled with
VC++ .NET and may or may not work with VC++ 6.0.  If not, you will have
to build them yourself until we provide VC6 binaries.)

* Alternative: Building the optional libraries yourself
=======================================================

If you need to build the libraries yourself, grab them from 
http://ftp.xemacs.org/pub/xemacs/aux or get the latest version from the
home page of the appropriate library, as listed on
http://www.xemacs.org/Download/optLibs.html.  The following instructions
assume that you have the appropriate libraries and have unpacked them
somewhere, e.g. c:\src.

Directions for building the various libraries:

1.  You really want the XPM library.  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.  Get PNG and ZLIB and read the
    respective READMEs for details on how to build them.

    cd to the ZLIB source directory and type 'nmake -f win32\Makefile.msc'.

    cd to the libpng source directory, rename or move the zlib directory to
    ..\zlib and type 'nmake -f scripts\makefile.vcawin32'.

3.  If you want TIFF support, cd to the TIFF source directory and type
    'nmake -f Makefile.vc'.

4.  If you want JPEG support, cd to the JPEG source directory and type
    'nmake -f makefile.vc'.

5.  If you want X-Face support, copy nt\compface.mak from the xemacs sources
    to the compface directory, cd to that directory and build libcompface
    with 'nmake -f compface.mak'.

6.  It's also possible to build the Sleepycat DB libraries.  Open up the file

    DB-SOURCE-DIR\docs\ref\build_win\intro.html

    in a browser, where DB-SOURCE-DIR is the top-level source directory for
    the Sleepcat DB libraries, and follow the directions.  You should build the
    `Release_static' target if you want to use the static version of this
    library, or the `Release' target if you want to use the DLL version of
    the library.  To use the DLL version, you need to set BUILD_DATABASE_SHARED
    to 1 in config.inc.  The DLL version will make the executable much smaller,
    but you will have to have the DLL present at run-time -- either in the
    same directory as the XEmacs executable or somewhere in your path.

7.  It's possible, but difficult, to build shared libraries for GNU MP.
    (Static libraries are not yet possible, as there is no makefile.vc for
    this; you can't build static libraries for VC++ using MinGW.) Basically,
    you need to build using MinGW and then generate native import libraries.
    This is more or less described in the documentation, but the following
    procedure seems to work:

    -- In the top level of the GMP sources, configure using

       CC='gcc -mno-cygwin' configure --build=pentium3-pc-mingw32 --disable-static --enable-shared

    -- Edit the `libtool' script in the same directory and change the value
       of CC from `gcc' to `gcc -mno-cygwin'.

    -- Run `make'.

    -- Run these commands:

       lib /machine:IX86 /def:.libs/libgmp-3.dll-def
       cp .libs/libgmp-3.dll-exp libgmp-3.exp
       cp .libs/libgmp-3.dll .

    -- You should now have an import library named libgmp-3.lib and a DLL
       libgmp-3.dll.

    -- NOTE: You will need to have this DLL accessible when XEmacs runs.
       It either needs to be in the same directory as the XEmacs executable
       or in your path.

8.  There are also pre-built binaries for GMP-4.1.2 at

    http://www.cs.nyu.edu/exact/core/gmp/.

    However, they don't seem to work properly for our purposes, as they
    require LIBC.LIB rather than MSVCRT.DLL.

9.  You can build the client library for PostgreSQL by cd'ing to the src/
    subdirectory of the PostgreSQL sources and running `nmake -f win32.mak'.

10.  It does not appear to be very easy to build OpenLDAP under
     native MS Windows, as it is only experimentally supported.  However, there
     is a mailing list for this, which contains postings of recent binaries and
     build patches; see

     http://lucas.bergmans.us/hacks/openldap/

     If you know how to build OpenLDAP, please write up a description of the
     process and send it to us at xemacs-beta@xemacs.org.


* Building
==========

1.  cd to the nt subdirectory of the xemacs distribution and copy the file
    config.inc.samp to config.inc.  Make any necessary modifications.  This
    file controls the options that XEmacs is built with:

    -- If you want international (aka "Mule") support, modify the appropriate
       line in config.inc as follows:

       MULE=1

    -- If you're using the pre-supplied optional library pack, all you should
       have to do is set OPTIONAL_LIBRARY_DIR to the top-level directory
       where you unpacked everything.

    -- By default, support is enabled for all graphics formats, but not
       currently for any of the other libraries in the optional library
       pack.  If you want support for GMP, Berkeley DB or PostgreSQL, set
       the appropriate flag (HAVE_BIGNUM, HAVE_DATABASE or HAVE_POSTGRESQL,
       respectively) to 1.  We do not currently enable these by default
       because of lack of sufficient testing, questionable usefulness in
       the case of Berkeley DB and PostgreSQL, excessive library size in
       the case of Berkeley DB (more than 2 MB for the static library!),
       and lack of a static library in the case of GMP.

    -- If you want to turn off support for any of the graphics libraries,
       set the appropriate flag (HAVE_XPM, HAVE_GIF, HAVE_PNG, HAVE_JPEG,
       HAVE_TIFF or HAVE_XFACE) to 0.

    -- If you have compiled some of the libraries yourself, you will have to
       specify the location of the top-level source directory for each of
       these libraries.  XEmacs assumes that the directory structure under
       these directories is as it is in the sources, rather than in any
       installed format.

       For example, for XPM support, modify the appropriate lines in
       config.inc as follows:

       HAVE_XPM=1
       XPM_DIR="x:\location\of\your\xpm\sources"
    
       Similarly for JPEG, TIFF, etc. support.

       For PNG support, you also need to specify ZLIB_DIR.
       For GIF support, no directory is necessary as the appropriate code
       is already in XEmacs.

       If you want to use the DLL version of the Sleepycat DB library,
       set BUILD_DATABASE_SHARED to 1.  You will have to have the DLL
       present at run-time -- either in the same directory as the XEmacs
       executable or somewhere in your path.

    -- By default, XEmacs will expect to find its packages in the
       subdirectories "site-packages", "mule-packages" and "xemacs-packages"
       under the directory "c:\Program Files\XEmacs". If you want it to look
       for these subdirectories elsewhere, modify the appropriate lines in
       config.inc as follows:

       PACKAGE_PREFIX="x:\your\package\directory"

       Make sure that the directory pointed to by PACKAGE_PREFIX contains
       the xemacs-packages directory into which you installed the packages.

    -- XEmacs can build its info files more quickly if you have a copy of the
       makeinfo program. If you have a copy, modify the appropriate lines in
       config.inc as follows:

       MAKEINFO="x:\location\of\makeinfo.exe"

       If you don't have a copy of makeinfo then you'll need to have installed
       the XEmacs texinfo package.

2.  If you want to install XEmacs when you build it, modify the appropriate
    lines in config.inc as follows (you can also run XEmacs from its build
    directory):

       INSTALL_DIR="x:\your\installation\directory"

    (By default, XEmacs will be installed in directories under the directory
    "c:\Program Files\XEmacs\XEmacs-21.5".)

3.  If you want the built files to go into a different tree than the source
    tree (e.g. this allows you to build multiple versions of XEmacs, with
    different configuration settings, from the same source tree), use the
    script `make-build-dir' to create a skeleton build tree, create a
    config.inc in that tree, and then run nmake from that tree.  This is
    similar to running `configure --srcdir=PATH' under Unix.  See the
    comments in `config.inc.samp' for more information.

4.  If you want to build xemacs on the command line, use
    `nmake install -f xemacs.mak', or just `nmake -f xemacs.mak' if you want
    to run XEmacs from its build directory.  nmake will build temacs, the DOC
    file, update the elc's, dump xemacs and (optionally) install the relevant
    files in the directories under the installation directory.

    If you chose to install XEmacs, the file that you should run to start
    XEmacs will be installed (by default) as
        "c:\Program Files\XEmacs\XEmacs-21.5\i586-pc-win32\xemacs.exe".

    To run from the build directory, run the file "src\xemacs.exe" off of the
    root of the build directory.

    You may want to create a shortcut to the file from your Desktop or
    Start Menu.

5.  To build using MS Visual Studio, you can use the workspace file
    `nt/xemacs.dsw'. This was prepared for Visual C++ 6.0.  If you are using
    Visual Studio .NET, open this file up inside of it and it will offer to
    convert it to a .NET "solution" file.  The same procedure should work
    for newer versions of Visual Studio (e.g. Visual Studio 2005).  If this
    doesn't work (e.g. you are using Visual C++ 5 or even earlier), just
    open up `nt/xemacs.mak' from within Visual Studio and it will offer to
    wrap this Makefile in a workspace file, from which you can build.
    Assuming you want to run from the build directory (which you will want
    to do if you are planning on doing any development work on XEmacs), use
    the following settings (for Visual C++ 6.0, at least) in
    Project/Settings...:

    Under the General tab:

    Build command line: NMAKE /f xemacs.mak
    Output file name: ..\src\xemacs.exe
    Browse info file name: ..\src\temacs.bsc

    Under the Debug tab:

    Executable for debug session: ..\src\xemacs.exe


    If you want to install XEmacs when it's built, change the build command
    line to "NMAKE install /f xemacs.mak". (You will have to make the same
    change even if you use the provided workspace nt/xemacs.dsw.)


* Debugging under MS Developer Studio
=====================================

The build process always creates debugging and "Source Browser" information
in the source tree for use with DevStudio. However that information is not
very useful unless you build a debug version of XEmacs:

1.  Set DEBUG_XEMACS=1 and DEPEND=1 in config.inc and rebuild.

2.  See instructions above for obtaining a workspace file for use with
    MS Developer Studio.  Build and debug your XEmacs this way.

3.  To display the contents of a lisp variable, type Shift-F9 (or use the
    menu) to bring up the QuickWatch window, type dp(variable) and click
    Recalculate. The output will appear in a console window, as well as in
    the Debug window in MS Developer Studio.

4.  To display a current Lisp backtrace, type db() in the QuickWatch window,
    as in the previous item.

5.  To view Lisp variables in the "Watch" window wrap the variable in one of
    the helper functions from the file src\console-msw.c, for example type
    DSTRING(variable) in the "Watch" window to inspect a Lisp string.

6.  For further information on debugging XEmacs, see the item
    `How to Debug an XEmacs problem with a debugger' in the XEmacs FAQ.
