When i'm working in a LaTeX-File everything works as expected. Compilation and completion via company-auctex are working perfectly. However when i want to make use of any preview-functionality inside my editing buffer (For example with C-c C-p C-p "preview at point" there is no preview, but an error buffer that ends with

Preview-Ghostscript exited abnormally with code 1

Configuration and AucTeX-setup is just

(use-package auctex
  :defer t
  :ensure t)

Does anyone have an idea what to do? Is maybe something missing in my config?

Emacs Version: 25.3.1 AucTeX Version: 12.1.1 Ghostscript Version: 9.22

All help will be highly appreciated.

  • It seems that Ghostscript isn't happy due to missing locale value: Unable to read environment locale. Maybe you check and set that and try it again. Mar 26, 2018 at 10:34
  • Thank you for your answer! Could you maybe tell me, how i would do that?

  • You can check the values by doing locale RET in a shell. For setting the values, I suggest you check the documentation of your distro and/or search the web. Mar 26, 2018 at 13:07
  • It seems like kde has automatically set my locales to be de_EN.UTF8 because i'm in Germany but prefer english as my OS-Language! However i changed it to de_DE.UTF8 and now preview functionality works. Thanks for your guidance @ArashEsbati
