Hi,
AUCTeX makes the invalid/irrelevant complaint
The mark is not set now, so there is no region
in the following situation:
(0) Save the two attached files in some directory.
(1) Start up a brand new emacs, editing the attached file latex-component.tex
(2) Type C-c C-b to compile the buffer; AUCTeX reports
Type ‘C-c C-l’ to display results of compilation.
LaTeX: successfully formatted {1} page
and there is indeed a _region_.pdf file with the expected contents.
So far so good.
(3) Now try to admire the PDF with C-c C-v
What I expected:
to see my PDF in a PDFview window
What actually happens:
AUCTeX now complains
The mark is not set now, so there is no region
I don't care about any mark or any region, I just want to see my PDF.
I hope this is enough details to cover the problem and other people can
reproduce it.
Thanks.
Jim
