I am a new user of emacs. I have installed emacs 27.1 in my Ubuntu 22.04. I can successfully open my ms.tex file in emacs (terminal). After that, I press the C-c C-c command and then I type my file name as ms.tex. It successfully creates the ms.pdf file in my directory. Then I press C-c C-c and then I type \doc-view ms.pdf RET. It does not show the actual pdf. It shows an encoded version of ms.pdf file. I also typed M-x doc-view-minor-mode RET on emacs. After that, I pressed C-c C-c then an error message appears, the message says that unable to render, view extracted text instead?. (y or n). After typing y RET it does not show the right pdf and it shows an error message which says Wrong type argument: number-or-marker-p, nil. I can open my ms.pdf file using evince ms.pdf externally but I can not open it in emacs. I searched my problem on google and based on some answers I have tried to modify my C-x C-f ~/.emacs.d/init.el file but it has not worked. After pressing M-x package-install after that I type pdf-tools it does not show anything. Ghostscript and xpdf are already in the newest version.

    I want to open pdf in emacs, meaning to say, after pressing the C-x C-f command and after pressing the C-c C-c command, I want to see my pdf file within emacs (not externally). After running pdflatex command the pdf should be updated automatically. Hope I have answered.

  • If Emacs is running inside of a terminal, then you cannot do that. Can you run the Emacs gui instead?

  • Yes. If I run emacs gui, I can open the pdf with \doc-view. I want to do the same thing using emacs terminal.
