Auctex requires a :pre-build step which involves generating elisp files. If that step fails, certain parts will break. There are several ways to configure the build as well. See the various issues on the bug tracker for more info. e.g,

Thanks for helping out.

Auctex is a notoriously tricky package to get built.

[–] Ok_Advisor1053@alien.top 1 points 11 months ago (1 children)

This is how I got it to work

```
(use-package tex
  :demand t                             
  :elpaca (auctex :pre-build (("./autogen.sh")
                              ("./configure"
                               "--with-texmf-dir=$(dirname $(kpsexpand '$TEXMFHOME'))")
                              ("make")))

... rest of your config)
```

"--with-texmf-dir=$(dirname $(kpsexpand '$TEXMFHOME'))")

didn't got this.

Also when i added the code to my init file it is returning error

[–] noobaster-pro-007@alien.top 1 points 11 months ago

Error (use-package): tex/:catch: Cannot open load file: No such file or directory, tex-site

Here is the solution I came up with, following the hints given by [[https://github.com/progfolio/elpaca/issues/191]]

 (defun ded:elpaca-build-dir (p)
    "Return the elpaca build directory for package symbol p"
    (-first-item
     (f-directories elpaca-builds-directory
  	                (lambda (dir) (string-match-p (concat "^" (symbol-name p) "$") (f-filename dir))))))

  (use-package auctex
    :elpaca (auctex :pre-build (("./autogen.sh")
                                ("./configure" "--without-texmf-dir" "--with-lispdir=.")
                                ("make")
                                ("install-info" "doc/auctex.info" "doc/dir")
                                ("install-info" "doc/preview-latex.info" "doc/dir")))
    :mode (("\\.tex\\'" . TeX-latex-mode)
           ("\\.tex\\.erb\\'" . TeX-latex-mode)
           ("\\.etx\\'" . TeX-latex-mode))
    :init
    (add-to-list 'Info-additional-directory-list (f-join (ded:elpaca-build-dir 'auctex) "doc"))
    (add-hook 'tex-mode-hook
              (lambda ()
                (load "auctex.el")
                (setq TeX-command-extra-options "-shell-escape")))
    :config
    (setq-default TeX-global-PDF-mode 1)
    (setq-default  preview-scale-function 1.5)
    (setq TeX-auto-save t
          TeX-parse-self t
          default-truncate-lines t
          TeX-save-query nil
