The lldb-enhanced gud.el is based on the emacs 22.3.1 version from Aquamacs 1.8c distribution. To use it, load the file from within emacs and type 'M-x lldb' to invoke lldb. The lldb-gud-window.png is a screen capture of the gud (with lldb) at work on Aquamacs distribution 2.1 by loading the gud.el in this directory and 'M-x lldb' on the ../../test/condition_break directory. -------------------------------------------------------------------------------- Versions of emacs that do not work: o This lldb-enhanced gud.el does not work on emacs 22.1.1 (dumb terminal). This is the error I got: Debugger entered--Lisp error: (void-function split-string-and-unquote) (split-string-and-unquote command-line) (let* ((words ...) (program ...) (dir default-directory) (file-word ...) (file-subst ...) (args ...) (file ...) (filepart ...) (existing-buffer ...)) (pop-to$ gud-common-init("/Volumes/data/lldb/svn/trunk/build/Debug/lldb" nil gud-lldb-marker-filter) lldb("/Volumes/data/lldb/svn/trunk/build/Debug/lldb") call-interactively(lldb) execute-extended-command(nil) call-interactively(execute-extended-command) The gud-common-init elisp function references split-string-and-unquote function which is not defined there. -------------------------------------------------------------------------------- Versions of emacs that do work (with minimal testing): o I downloaded the Emacs Version 23.2 (Released 2010-05-08) from http://emacsformacosx.com/, ran it with "/Volumes/data/Applications/Emacs.app/Contents/MacOS/Emacs -nw" (as a dumb terminal application), loaded the gud.el file, cd to test/breakpoint_condition, and M-x lldb to run my built lldb against the a.out executable, it seems to work ok.
