Do not use this recipe with Cygwin. For building on Cygwin,
use the normal installation instructions, ../INSTALL.
+ If you have a Cygwin or MSYS port of Bash on your Path, you will be
+ better off removing it from PATH. (For details, search for "MSYS
+ sh.exe" below.)

since v1.3.3, include the MinGW headers and libraries as an integral
part).

The rest of this file assumes you have a working development
environment. If you just installed such an environment, try
for example). Also see the Trouble-shooting section below if you
decide to go ahead and use Cygwin make.
- In addition, using 4NT or TCC as your shell is known to fail the build
- process, at least since 4NT version 3.01. Use CMD.EXE, the default
- Windows shell, instead. MSYS sh.exe also appears to cause various
- problems. If you have MSYS installed, try "make SHELL=cmd.exe" to
- force the use of cmd.exe instead of sh.exe.

absolutely sure the produced binaries will never need to be run under
a debugger.
+ Because of limitations of the stock Windows command shells, special
+ care is needed to pass some characters in the arguments of the
+ --cflags and --ldflags options. Backslashes should not be used in
+ file names passed to the compiler and linker via these options. Use
+ forward slashes instead. If the arguments to these two options
+ include the `=' character, like when passing a -DFOO=bar preprocessor
+ option, the argument with the `=' character should be enclosed in
+ quotes, like this:
+
+ configure --cflags "-DFOO=bar"
+
+ Support for options that include the `=' character require "command
+ extensions" to be enabled. (They are enabled by default, but your
+ system administrator could have changed that. See "cmd /?" for
+ details.) If command extensions are disabled, a warning message might
+ be displayed informing you that "using parameters that include the =
+ character by enclosing them in quotes will not be supported."
+
+ You may also use the --cflags and --ldflags options to pass
+ additional parameters to the compiler and linker, respectively; they
+ are frequently used to pass -I and -L flags to specify supplementary
+ include and library directories. If a directory name includes
+ spaces, you will need to enclose it in quotes, as follows
+ -I"C:/Program Files/GnuTLS-2.10.1/include". Note that only the
+ directory name is enclosed in quotes, not the entire argument. Also
+ note that this functionality is only supported if command extensions
+ are available. If command extensions are disabled and you attempt to
+ use this functionality you may see the following warning message
+ "Error in --cflags argument: ... Backslashes and quotes cannot be
+ used with --cflags. Please use forward slashes for filenames and
+ paths (e.g. when passing directories to -I)."
+
N.B. It is normal to see a few error messages output while configure
is running, when gcc support is being tested. These cannot be
suppressed because of limitations in the Windows 9X command.com shell.
library is not an error; the associated image format will simply be
unavailable. Note that once Emacs has determined that a library can
not be found, there's no way to force it to try again, other than
- restarting. See the variable `image-library-alist' to configure the
+ restarting. See the variable `dynamic-library-alist' to configure the
expected names of the libraries.
Some image libraries have dependencies on one another, or on zlib.
If GTK 2.0 is installed, addpm will arrange for its image libraries
to be on the DLL search path for Emacs.
+ For PNG images, we recommend to use versions 1.4.x and later of
+ libpng, because previous versions had security issues. You can find
+ precompiled libraries and headers on the GTK download page for
+ Windows (http://www.gtk.org/download-windows.html).
+
+ Versions 1.4.0 and later of libpng are binary incompatible with
+ earlier versions, so Emacs will only look for libpng libraries which
+ are compatible with the version it was compiled against. That
+ version is given by the value of the Lisp variable `libpng-version';
+ e.g., 10403 means version 1.4.3. The variable `dynamic-library-alist'
+ is automatically set to name only those DLL names that are known to
+ be compatible with the version given by `libpng-version'. If PNG
+ support does not work for you even though you have the support DLL
+ installed, check the name of the installed DLL against
+ `dynamic-library-alist' and the value of `libpng-version', and
+ download compatible DLLs if needed.
+
+* Optional GnuTLS support
+
+ If configure.bat finds the gnutls/gnutls.h file in the include path,
+ Emacs is built with GnuTLS support by default; to avoid that you can
+ pass the argument --without-gnutls.
+
+ In order to support GnuTLS at runtime, a GnuTLS-enabled Emacs must
+ be able to find the relevant DLLs during startup; failure to do so
+ is not an error, but GnuTLS won't be available to the running
+ session.
+
+ You can get pre-built binaries (including any required DLL and the
+ gnutls.h file) and an installer at http://josefsson.org/gnutls4win/.

* Experimental SVG support
SVG support is currently experimental, and not built by default.
Removes the installed files in the bin subdirectory in addition to
the files removed by make cleanall.
+ make dist
+ Builds Emacs from the available sources and pre-compiled lisp files.
+ Packages Emacs binaries as full distribution and barebin distribution.
The following targets are intended only for use with the Bazaar sources.
bootstrap to rebuild. Occasionally it may be necessary to run this
target after an update.
+* Creating binary distributions
+
+ Binary distributions (full and barebin distributions) can be
+ automatically built and packaged from source tarballs or a bzr
+ checkout.
+
+ When building Emacs binary distributions, the --distfiles argument
+ to configure.bat specifies files to be included in the bin directory
+ of the binary distributions. This is intended for libraries that are
+ not built as part of Emacs, e.g. image libraries.
+
+ For example, specifying
+
+ --distfiles D:\distfiles\libXpm.dll
+
+ results in libXpm.dll being copied from D:\distfiles to the
+ bin directory before packaging starts.
+
+ Multiple files can be specified using multiple --distfiles arguments:
+
+ --distfiles D:\distfiles\libXpm.dll --distfiles C:\jpeglib\jpeg.dll
+
+ For packaging the binary distributions, the 'dist' make target uses
+ 7-Zip (http://www.7-zip.org), which must be installed and available
+ on the Windows Path.
