cscope-index-files always shows "No match"

Question

I've installed cscope and using xcscope.el in emacs.

I want to index my files in Emacs with cscope-index-files. But when setting the directory, it always says No match.

Answer 1

The cscope-index-files command expects the user to provide a valid directory via the minibuffer, when invoked interactively. You can tell from the source code, in xcscope.el, by the first character of the string provided to the interactive function, in this case "D" which means directory:

(defun cscope-index-files (top-directory)
  (interactive "DIndex files in directory: ")
...

When I run M-x cscope-index-files, I see emacs say No match if I provide a directory that doesn't exist e.g. ~/aaaaa; in this case emacs will not accept it, and the minibuffer displays ~/aaaaa[No match]. Are you providing a valid directory when you invoke cscope-index-files?
