I've hit a brick wall with this. I'm running cygwin on a Windows 7 machine. I can't connect vai ange-ftp to an ftp server, hosted by godaddy.com. I do C-x C-f /[email protected]: (to get a dir listing) or :index.html (file exists), and in both cases emacs asks me for my password, I enter it, and then emacs freezes. Hard freezes - only way to kill it is to use Task Manager, and kill two emacs-w32 processes.

I'm using the cygwin emacs-w32 program.

My .emacs includes (require 'cygwin-mount). I also tried (require 'setup-cygwin) (downloaded most recent version today), but that doesn't load properly. Error about "cannot find cygwin", having to do with a variable that sets the path to cygwin. I couldn't figure it out so commented out (require 'setup-cygwin).

So - suggestions? Could this relate to what ftp client emacs / ange-ftp is finding? Other things about my emacs setup for cygwin? I've been using cygwin emacs for about 6 months and most other things work, including running processes from within emacs (shell, tex, grep, diff, etc).


Here's the result of emacs-w32 --debug-init with (require 'steup-cygwin) in my .emacs. Alas I can't give any error info on the actual ange-ftp issue, since emacs just freezes.

Debugger entered--Lisp error: (wrong-type-argument stringp nil)

  load("~/.emacs" t t)

**** With new setup-cygwin.el from Drew, it behaves as he said. The relevant part of .emacs is:

(require 'cygwin-mount)
(setq cygwin-root-directory "/c/cygdrive/cygwin64/")
(require 'setup-cygwin)

Startup now works. C:/cygwin64/ didn't.

And ange-ftp works! Once I put ftp in passive mode to get around firewall. Success!

  • Try to post the exact error message(s). That might help someone help you. And start Emacs using the switch --debug-init.

  • OK, I just did what you asked. It may help sort out setup-cygwin, but won't directly address the ange-ftp error.

The error tells you the problem, I think:

Cannot find Cygwin. Please customize option `cygwin-root-directory'

You need to set that variable. Use M-x customize-option RET cygwin-root-directory RET to do that.

(That said, the code should have handled a non-string argument to setcyg-dir-p. Download the latest setup-cygwin.el to get that fix.)

  • Thanks! I actually downloaded that file this morning. So I think the current version gives the error.

  • I just updated it, before I wrote that. The error is correct - you need to customize the option. The minor fix to the code was to return nil if the value is not a string. Your problem does not come from setup-cygwin.el; it comes from your not having defined option cygwin-root-directory.

  • Yeah, you're right, I forgot to refresh the browser tab viewing that file from yesterday morning. My fault. I updated my question with more info. Now it loads. On to ange-ftp.
