Don't use them. 20.x will not work, 21.0.x were prereleases, anyway.
As of GNU Emacs 21.2, no image support is available in Emacs under
Windows. Without images, preview-latex is useless. The current
CVS version of Emacs available from
http://savannah.gnu.org/projects/emacs now is supposed to
support images, so it is likely that Emacs 21.4 will have a
reasonable chance of working once it is out. However, as of this
writing, no support for the png
image format seems to be
available in GNU Emacs for Windows. In this case, you can try using
the pnm
image format, but we recommend that you get an Emacs
version that supports png
images (and if none is available we
recommend that you complain to your Emacs deliverer). If it is
important to you and you have the necessary technical skills, support
the Emacs developer crew by checking out the current version and
trying to get preview-latex to run on it. Reasonable patches
necessary to make preview-latex work under Windows will gladly be
accepted. Another option for Windows users might be to try XEmacs
(see below).
XEmacs support should now work.
There is are two current problems known with the XEmacs core. One leads to seriously mispositioned baselines and previews hanging far above other text on the same line. An alpha-quality patch against XEmacs-21.4.6 to fix this is available from http://list-archive.xemacs.org/xemacs-patches/200204/msg00129.html. This patch in included in XEmacs-21.4.9, but won't be present in any earlier version, with one exception: the MS Windows port had incorporated these fixes a few version numbers earlier.
The other core bug causes a huge delay when XEmacs's idea of the state of processes (like ghostscript) is wrong, and can lead to nasty spurious error messages. It should be fixed in version 21.4.8.
Previews will only remain from one session to the next if you have
version 1.81 or above of the edit-utils
package, first released
in the 2002-03-12 sumo tarball.
By now we have had success reports of both Cygwin XEmacs and the native
Windows ports (one Cygwin user reported that he had to disable
balloon-help-mode
in preview-mode-setup
in the file
prv-xemacs.el
, please report back your experiences). If you are
lacking the usual infrastructure for the installation process of
preview-latex, things will become more complicated.
See Installation under MS Windows for an installation report for this platform.
