and describe here what you see there when it reports the error. Everything else is just noise, as far as investigation of this problem is concerned.
Using Edebug on the instrumented insert-directory function narrows in on lisp/files.el ''' 7502 (apply 'call-process 7503 insert-directory-program nil t nil 7504 (append 7505 (if (listp switches) switches 7506 (unless (equal switches "") 7507 ;; Split the switches at any spaces so we can 7508 ;; pass separate options as separate args . 7509 (split-string-and-unquote switches))) 7510 ;; Avoid lossage if FILE starts with `-'. 7511 '("--") 7512 (list file)))))) ''' The "result" exit status is "1" on line 7512 closing parenthesises. The call is "ls -al -- /usr/X" and the problem is Plan's ls doesn't take the "-a" switch. For example ''' % ls -a usage: ls [-dlmnpqrstuFQ] [file ...] % echo $? 1 % ls -al usage: ls [-dlmnpqrstuFQ] [file ...] % echo $? 1 ''' The Edebug steps continue to line 7581. lisp/files.el:7581 "Listing directory failed but `access-file' worked" In the case of Plan9's ls what is needed is to leave out the "-a" switch. -- vl
