I had the same problem in Fedora 13 and 14. There is a patch for this bug in the cvs version of auctex 11.86: http://cvs.savannah.gnu.org/viewvc/auctex/preview/preview.el?root=auctex&r1=1.284&r2=1.285&view=patch I applied that patch to /usr/share/emacs/site-lisp/auctex/preview.el, from the emacs-auctex-el package, then recompiled that elisp file into a .elc file, and it worked. Previews now work in Emacs with auctex. When applying the patch, there was a message that 1 of the 6 patch hunks failed. Namely, the fifth hunk: --------------------------------------------------------- @@ -3512,7 +3519,7 @@ (defconst preview-version (eval-when-compile (let ((name "$Name: $") - (rev "$Revision: 1.284 $")) + (rev "$Revision: 1.285 $")) (or (when (string-match "\\`[$]Name: *release_\\([^ ]+\\) *[$]\\'" name) (setq name (match-string 1 name)) (while (string-match "_" name) --------------------------------------------------------- It looks like the '(let ((name "$Name: $")' line didn't quite match what was in the old preview.el, so I just manually changed the revision number from 1.284 to 1.285 in preview.el before recompiling it.

Fix bug in Auctex previews not working in Emacs in Fedora 13/14
Modified patch for /usr/share/emacs/site-lisp/auctex/preview.el from the emacs-auctex-el package.
Save as preview-el.patch then run:
patch /usr/share/emacs/site-lisp/auctex/preview.el preview-el.patch
Then open /usr/share/emacs/site-lisp/auctex/preview.el in Emacs, select the Emacs-Lisp menu and select the "Byte-compile this File".

Description of problem: Generating previews of equations etc. in LaTeX documents doesn't work with Emacs-AucTeX. After I try to generate previews for the buffer, the messages buffer is left with: Saving file /home/james/docs/_region_.tex... Wrote /home/james/docs/_region_.tex Wrote /home/james/docs/prv_mydoc.ini Type `C-c C-l' to display results of compilation. [2 times] locating previews... Mark set Type `C-c C-l' to display results of compilation. but the editor is left with untypeset equations with red "No Entry" icons besides them. Inspecting _region_.prv/ reveals a PS file containing all the typeset equations, but they don't seem to make it back to the editor. If I right-click on one of the "No Entry" icons and select View error, I see something like: gs -dOutputFile\=\(_region_.prv/tmp16143D-x/pr1-11.png\) -q -dSAFER -dNOPAUSE -DNOPLATFONTS -dPrinted -dTextAlphaBits\=4 -dGraphicsAlphaBits\=4 -sDEVICE\=png16m -r94.2656x94.3773 GS>{DELAYSAFER{.setsafe}if}stopped pop/.preview-BP currentpagedevice/BeginPage get dup null eq{pop{pop}bind}if def<</BeginPage{currentpagedevice/PageSize get dup 0 get 1 ne exch 1 get 1 ne or{.preview-BP }{pop}ifelse}bind/PageSize[1 1]>>setpagedevice/preview-do{[count 3 roll save]3 1 roll dup length 0 eq{pop}{setpagedevice}{ifelse .runandhide}stopped{handleerror quit}if aload pop restore}bind def [(_region_.prv/tmp16143D-x/preview.ps)(r)file]aload exch dup 0 setfileposition 24763()/SubFileDecode filter cvx .runandhide aload pop dup dup 24763 setfileposition 102()/SubFileDecode filter cvx<<>>preview-do Error: /typecheck in --setfileposition-- Operand stack: --nostringval-- (_region_.prv/tmp16143D-x/preview.ps) (r) (r) (r) 25807 25807 25807 25690 25690 25690 25557 25557 25557 25456 25456 25456 25355 25355 25355 25253 25253 25253 25151 25151 25151 25029 25029 25029 24865 24865 24865 24763 Execution stack: %interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- %loop_continue --nostringval-- --nostringval-- false 1 %stopped_push .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- Dictionary stack: --dict:1157/1684(ro)(G)-- --dict:0/20(G)-- --dict:72/200(L)-- Current allocation mode is local Current file position is 30 GS<33> I've seen elsewhere that this may be a ghostscript problem, but I've reported it against auctex as a starting point. Version-Release number of selected component (if applicable): tex-preview-11.86-2.fc13.noarch ghostscript-8.71-19.fc13.x86_64 emacs-auctex-11.86-2.fc13.noarch emacs-23.2-4.fc13.x86_64 How reproducible: Always. Steps to Reproduce: 1. Write LaTeX document in auctex-enabled Emacs. 2. Go to Emacs menu, select Preview, for buffer. Actual results: Equations still in $$ input form with "No Entry" icons to the left. Expected results: Typeset previews.
