Hi, I tried the latest slime snapshot (2007-09-26) on Windows XP with NTEmacs 23.0.0.1 and SBCL 1.0.9. I have a file with some functions in e.g. d:/projects/test/test.lisp. When I try to compile a defun in this file with slime-compile-defun (C-c C-c), tramp starts and dies, trying to ssh to "d". I traced the bug down to the return of the function slime-file-name-merge-source-root: (return (concat (file-name-as-directory "/") target-suffix (file-name-nondirectory target-filename)))))))))) The problem is that this functions returns "/d:/projects/test/test.lisp" to slime-maybe-warn-for-different-source-root (guessed-target), and then used as an argument to file-exists-p. This function thinks it is a network path and then launches tramp. As a quick fix I removed (file-name-as-directory "/") from the return, what naturally just works on windows. But as a lisp starter I don't know how to really fix this bug. Thanks, Stefan -- Psssst! Schon vom neuen GMX MultiMessenger gehört? Der kanns mit allen: http://www.gmx.net/de/go/multimessenger
