Subject: bug#73854: 29.4; tex-mode: unexpected and inconsistent behaviour of `tex-compile`, `tex-file`, and `tex-view`
Date: Thu, 17 Oct 2024 18:36:19 +0000

Basically, `tex-view` works, opening Evince, on a compiled .pdf only
after a .dvi is created.

Running 'emacs -Q' I evaluate the following in the scratch buffer, to
make it so that latex is compiled to pdf:
```
(setq tex-print-file-extension ".pdf"
      tex-dvi-view-command "evince"
      tex-dvi-print-command "lpr")
```
the last two lines are following the instructions on the description of
`tex-print-file-extension`.

I navigate to a simple .tex in an empty directory and press `C-c C-c`
which is bound by default to `tex-compile`, I press enter, as the
default is `pdflatex`, and the file compiles, creating a .pdf in the
directory. After that I press `C-c C-v`, which is bound to `tex-view`
but Evince does not open, instead I get the message "tex-print: No
appropriate ‘.dvi’ file could be found. If I press `C-c C-f`
(`tex-file`) after that, a .dvi file is created, and now `tex-view`
works, meaning it opens the .pdf with Evince.

The fact that `tex-view` works on the .pdf only when a .dvi is first
created seems like a bug.
