[OS X Emacs] Re: Preview-latex errors

[Dave Burnham]

Pete,

Thanks for the help. I've made some progress, but it's still not fully
working yet.

I think that most of the problems are related to preview-latex being
able to find the programs it needs. As mentioned before, I had to
modify PATH in my .emacs so that AUCTeX could find latex, gs, and
their friends. However, it seems that this doesn't fix
preview-latex. I had to set preview-gs-command to the full path
(/usr/local/bin/gs) to make it work. Not sure how I missed this
before.

Two issues remain:

1) Running preview-document still fails with the "LaTeX found no
preview images" error. However, preview-buffer, preview-section,
etc. work fine.

2) If I switch AUCTeX to use PDFLaTeX (C-c C-t C-p) I get a
GhostScript errors for all of the places where I should see
preview-images. I've attached a sample error at the end of this
message. I think the relevant line is "Error: /typecheck in
--setmatrix--" but I know very little about GS. I can live without
PDFLaTeX for the moment, but eventually I'd like to get it working.

It turns out that doc-view suffers from the same problems with the
PATH. I also had to specify the full paths to all the executables
needed by doc-view to make it work.

I'm running Panther 10.5.5 on an Intel Mac.
