* Optional image library support
In addition to its "native" image formats (pbm and xbm), Emacs can
- handle other image types: xpm, tiff, gif, png and jpeg (postscript is
- currently unsupported on Windows). To build Emacs with support for
- them, the corresponding headers must be in the include path when the
- configure script is run. This can be setup using environment
- variables, or by specifying --cflags -I... options on the command-line
- to configure.bat. The configure script will report whether it was
- able to detect the headers. If the results of this testing appear to be
- incorrect, please look for details in the file config.log: it will show
- the failed test programs and compiler error messages that should explain
- what is wrong. (Usually, any such failures happen because some headers
- are missing due to bad packaging of the image support libraries.)

To use the external image support, the DLLs implementing the
functionality must be found when Emacs first needs them, either on the

Binaries for the image libraries (among many others) can be found at
- the GnuWin32 project. These are built with MinGW, but they can be
- used with both GCC/MinGW and MSVC builds of Emacs. See the info on
+ the GnuWin32 project. PNG, JPEG and TIFF libraries are also
+ included with GTK, which is installed along with other Free Software

+ with both GCC/MinGW and MSVC builds of Emacs. See the info on
http://ourcomments.org/Emacs/w32-build-emacs.html, under "How to Get
Images Support", for more details about installing image support
libraries. Note specifically that, due to some packaging snafus in
_source_ packages for some of the libraries in order to get the
header files necessary for building Emacs with image support.
+ If GTK 2.0 is installed, addpm will arrange for its image libraries
+ to be on the DLL search path for Emacs.
+
+* Experimental SVG support
+
+ SVG support is currently experimental, and not built by default.
+ Specify --with-svg and ensure you have all the dependencies in your
+ include path. Unless you have built a minimalist librsvg yourself
+ (untested), librsvg depends on a significant chunk of GTK+ to build,
+ plus a few Gnome libraries, libxml2, libbz2 and zlib at runtime. The
+ easiest way to obtain the dependencies required for building is to
+ download a pre-bundled GTK+ development environment for Windows.
+ GTK puts its header files all over the place, so you will need to
+ run pkgconfig to list the include path you will need (either passed
+ to configure.bat as --cflags options, or set in the environment).
+
+ To use librsvg at runtime, ensure that librsvg and its dependencies
+ are on your PATH. If you didn't build librsvg yourself, you will
+ need to check with where you downloaded it from for the
+ dependencies, as there are different build options. If it is a
+ short list, then it most likely only lists the immediate
+ dependencies of librsvg, but the dependencies themselves have
+ dependencies - so don't download individual libraries from GTK+,
+ download and install the whole thing. If you think you've got all
+ the dependencies and SVG support is still not working, check your
+ PATH for other libraries that shadow the ones you downloaded.
+ Libraries of the same name from different sources may not be
+ compatible, this problem was encountered with libbzip2 from GnuWin32
+ with libcroco from gnome.org.
+
+ If you can see etc/images/splash.svg, then you have managed to get
+ SVG support working. Congratulations for making it through DLL hell
+ to this point. You'll probably find that some SVG images crash
+ Emacs. Problems have been observed in some images that contain
+ text, they seem to be a problem in the Windows port of Pango, or
+ maybe a problem with the way Cairo or librsvg is using it that
+ doesn't show up on other platforms.

* Building
After running configure, simply run the appropriate `make' program for

to create a Start menu icon for Emacs.
+* Make targets
+
+ The following make targets may be used by users building the source
+ distribution, or users who have checked out of CVS after
+ an initial bootstrapping.
+
+ make
+ Builds Emacs from the available sources and pre-compiled lisp files.
+
+ make install
+ Installs programs to the bin directory, and runs addpm to create
+ Start Menu icons.
+
+ make clean
+ Removes object and executable files produced by the build process in
+ the current configuration. After make clean, you can rebuild with
+ the same configuration using make.
+
+ make distclean
+ In addition to the files removed by make clean, this also removes
+ Makefiles and other generated files to get back to the state of a
+ freshly unpacked source distribution. Note that this will not remove
+ installed files, or the results of builds performed with different
+ compiler or optimization options than the current configuration.
+ After make distclean, it is necessary to run configure.bat followed
+ by make to rebuild.
+
+ make cleanall
+ Removes object and executable files that may have been created by
+ previous builds with different configure options, in addition to
+ the files produced by the current configuration.
+
+ make realclean
+ Removes the installed files in the bin subdirectory in addition to
+ the files removed by make cleanall.
+
+
+ The following targets are intended only for users who have checked out
+ of CVS.
+
+ make bootstrap
+ Creates a temporary emacs binary with lisp source files and
+ uses it to compile the lisp files. Once the lisp files are built,
+ emacs is redumped with the compiled lisp.
+
+ make recompile
+ Recompiles any changed lisp files after a cvs update. This saves
+ doing a full bootstrap after every update. If this or a subsequent
+ make fail, you probably need to perform a full bootstrap, though
+ running this target multiple times may eventually sort out the
+ interdependencies.
+
+ make maintainer-clean
+ Removes everything that can be recreated, including compiled lisp
+ files, to get back to the state of a fresh CVS checkout. After make
+ maintainer-clean, it is necessary to run configure.bat and make
+ bootstrap to rebuild. Occasionally it may be necessary to run this
+ target after a cvs update.

* Trouble-shooting
The main problems that are likely to be encountered when building
headers it is using, are not suitable for building Emacs. GCC version
2.95 or later is needed, because that is when the Windows port gained
sufficient support for anonymous structs and unions to cope with some
- definitions from winnt.h that are used by addsection.c. The W32 API
- headers that come with Cygwin b20.1 are incomplete, and do not include
- some definitions required by addsection.c, for instance. Also, older
- releases of the W32 API headers from Anders Norlander contain a typo
- in the definition of IMAGE_FIRST_SECTION in winnt.h, which
- addsection.c relies on. Versions of w32api-xxx.zip from at least
- 1999-11-18 onwards are okay.
+ definitions from winnt.h that are used by addsection.c.
+ Older versions of the W32 API headers that come with Cygwin and MinGW
+ may be missing some definitions required by Emacs, or broken in other
+ ways. In particular, uniscribe APIs were added to MinGW CVS only on
+ 2006-03-26, so releases from before then cannot be used.
When in doubt about correctness of what configure did, look at the file
config.log, which shows all the failed test programs and compiler
