since some time I have encountered a problem with opening pdf links with pdf-tools. I am using doom-emacs and have just the line
(add-to-list 'org-file-apps '("\\.pdf\\'" . org-pdfview-open))
to select the viewer in my config.
Previously all worked well. Now for some reason I can open pdfs with
counsel-find-file or other commands. But if I press enter on a pdf link I get
Symbol’s function definition is void: org-pdfview-open
I know it's hard to determine the error source without seeing everything in detail, but what could it be?
