preview-latex requires explicitely GNU Emacs with a version of at least 21.1. Concerning XEmacs, it is reported that it works for versions starting with 21.1.14 (with and without Mule). It is not expected to work with any with any version prior to this. The operation of versions before 21.4.9 suffers from some `cosmetic' problems:
Vertical constructs such as superscripts are not displayed correctly in XEmacs. This is a known bug of the XEmacs display engine and supposed to be solved in version 21.4.9 for the X Window System version. For MS Windows, this bug has been fixed in 21.4.8.
We recommend to use GNU or AFPL GhostScript with a version of at least 6.51. Versions above 7.xx have better antialiasing.
We also recommend strongly to use at least AUC TeX-11.14. Versions
prior to that may work but are known to cause problems with multiple
directories, as well as with detection of text locations for previews
generated by partial TeX compilations. The latter problem can be
patched for version 10.0g, see the patches
directory of the
preview-latex distribution.
We recommend keeping the variable preview-image-type
set to
png
. This is the default and can be set via the
Preview/Customize menu.
All other formats are known to have inconveniences, either in file size or quality. There are some Emacs versions around not supporting PNG, the proper idea to deal with that is to complain to your Emacs providers. Short of that, checking out PNM or JPEG formats might be a good way to find out whether the lack of PNG format support might be the only problem with your Emacs.
It is known to work under the X Window System for Linux and for several flavors of Unix: we have reports for HP and Solaris.
It works for Win9x under the cygwin version of XEmacs; however it is very slow! According to recent reports, it should also work for the native port, starting with preview-latex 0.7.3. It currently does not work for the GNU Emacs port to Win9x because of a lack of image support in currently released GNU Emacs versions under Win9x.
The entry "X11/Unix" currently means Linux, Solaris or HP/UX, as well as the X-specific version for Mac/OSX.
OS | Emacs version | XEmacs version
|
X11/Unix | 21.1 | 21.4.9
|
Win9x cygwin | CVS? | 21.4.8
|
Win9x native | CVS? | 21.4.8

With display errors, XEmacs versions as early as 21.1.14 might also work.
