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
