I have trouble getting the doc-view-mode displaying pdfs. Here's the error message generated :

No PNG support is available, or some conversion utility for pdf files is missing.

From what I've gathered, I must make sure that gs is in emacs path variable. Again, all of this looks good, the path given by

$which gs

is also found in (getenv "PATH").

So I'm not too sure where the bug comes from, any idea?

Running OS X 10.10.3, Emacs 24.4, ghostscript 9.15

    It should work out of the box if you have Ghostscript properly installed. Try setting the absolute path to the Ghostscript executable by adding to your `.emacs` file the following code `(setq doc-view-ghostscript-program "/path/to/gs")` Then, restart Emacs and try opening a `*.pdf` file and see if you get the same error. If it works, then you know the problem is not a missing something or other. – lawlist Mar 31 '15 at 01:45
  • Working, Thanks ! Perhaps you could put your comment in an answer so I can accept it. – Literal Mar 31 '15 at 01:53
  • So it's really the "PATH" variable that's responsible for it? Because as I said, both my $PATH (of the system) and the "PATH" of emacs include the directory where gs is found (`usr/local/bin`) – Literal Mar 31 '15 at 02:54
