[OS X Emacs] guess-TeX-master problem

[Hofert Jan Marius]

Dear all,

I installed of Aquamacs 2.3a on a MacBook Pro 10.6.8. I was hoping that the solution posted under the subject "Wiki code not working: Symbol's function definition is	void: guess-TeX-master" worked again, but it doesn't (and I don't know why). The goal is to get Aquamacs to compile an example.tex document which does not have a proper header but is simply a tex file included in a "master .tex file", call it master.tex. 

Following the previous posts, I have these entries in Preferences.el (just in case this has any influence on the problem, I included other commands too (only those that also affect latex mode; apart from that, I only have some R commands defined in Preferences.el)):

Now if I have opened example.tex (with or without opened master.tex) and I hit C-c C-c to compile it with latex, I face the following behavior:

(1) Many errors are produced (like \begin{document} is missing etc.). Here is the beginning of the output:

Running `LaTeX' on `example' with ``pdflatex --synctex=1 -interaction=nonstopmode "\input" example.tex''

! LaTeX Error: Missing \begin{document}.
...

(2) A strange behavior is also that instead of stopping after the first error, latex runs and runs until it finally stops with:
!  ==> Fatal error occurred, no output PDF file produced!
Transcript written on chapter.log.
LaTeX exited abnormally with code 1 at Thu Sep 15 10:41:36

Is there anything I have missed in the settings? typically, latex should stop after the first error. Then, there should not be any error if master.tex was found correctly.... hmmm... 

Cheers,

Marius
