Re: [Bug-AUCTeX] 11.86; auctex does not work properly if TeX-engine is set to luatex

[Carlos Russo]

Hi again,

I think the problem is the fact that LaTeX and lualatex behave differently to 
the same command line.

If  I look at the output of  lualatex, I get:

Running `LaTeX' on `test' with ``lualatex --synctex=1 -interaction=nonstopmode 
"\input" test.tex''
This is LuaTeX, Version beta-0.60.2-2010071217 (TeX Live 2010) (rev 3736) 
 restricted \write18 enabled.

It turns out the problem here is the "\input" part!
If I go to the command line and type
lualatex --synctex=1 -interaction=nonstopmode test.tex'

the file test.pdf is produced, as expected, whereas if I include the "\input" 
part, the texput.pdf file is produced instead.

How can I  fix this?
I suppose I need to put something on my .emacs, but I have no clue what.... 
help! :)

Cheers,
Carlos
