Hi,

I apologize if this is a repeat issue but I don't recall it.  I'm also sending it to "help" instead of "devel" -- I hope that is right.

I'm running emacs 24.0.90 on a Mac 10.7.2.  I open a pdf and it first appears as raw text.  I try "doc-view-mode" and I get this stack (after setting debug-on-error).

>   locate-file-internal(nil ("/usr/bin" "/bin" "/usr/sbin" "/sbin" "/Applications/Emacs.app/Contents/MacOS/libexec" "/Applications/Emacs.app/Contents/MacOS/bin" "/usr/local/bin") ("") 1)
>   locate-file(nil ("/usr/bin" "/bin" "/usr/sbin" "/sbin" "/Applications/Emacs.app/Contents/MacOS/libexec" "/Applications/Emacs.app/Contents/MacOS/bin" "/usr/local/bin") ("") 1)
>   executable-find(nil)
>   doc-view-initiate-display()
>   doc-view-mode()
>   call-interactively(doc-view-mode t nil)
>   execute-extended-command(nil)
>   call-interactively(execute-extended-command nil nil)


I did the "normal" Mac build process:

./configure --with-ns
make install

I have not dug into it but I'm hoping this might be an easy "pilot error"...

Thank you,
pedz

It seems you've built emacs without PNG support, or ghostscript is not
on your PATH.  Therefore, doc-view falls back to show you the plain text
contents of the PDF, and then it fails because
`doc-view-pdftotext-program' is also not oun your PATH.

The reason for not showing the PDF as images should be messaged, so
check your *Messages* buffer.

Bye,

Ahh... yes:

You might want to edebug `doc-view-mode-p' in order to see what's
actually missing.
