I think it learns it from gdb. gdb learns if from the debugging symbols in the executable. I think there is some interaction with some emacs settings because I've had situations where I've been unable to insert a breakpoint in a file by clicking in the left margin, but emacs has been able to bring me to the right line when gdb stops at a breakpoint inserted the old fashion way. > * after i open a file, how can I setup a break point at a particular line? If gdb is active and emacs and gdb agree that the file you've opened is a source file (usually, but not always true in my experience), you can just left click in the left margin. I'm responding on-list to this because other people might be able to give better answers.

As its name implies, it's for temporary files and, on many systems, all files in it get deleted every time the system reboots. > >>> I do something like this in my .emacs: > >>> > >>> (defun my-gdb () > >>> (interactive) > >>> (setq gdb-many-windows nil) nil is default anyway. > >>> (setq gdb-use-separate-io-buffer nil) nil is default anyway. > >>> (tool-bar-mode t) (add-hook 'gdb-mode-hook '(lambda () (tool-bar-mode 1)) > >>> (set-fringe-mode 'default) > >>> (gdb "/tmp/mygdb --annotate=3")) This starts gdb without an executable. You could add it to the string argument but one day you might want to debug another program. Using: (setq gud-gdb-command-name "/pathto/yourgdb --annotate=3") in your .emacs (or using customize to set it) means you will be prompted for (or Emacs will suggest) an executable name. > Right now, I need to do this at a shell in order to remote debug a c++ program. > $ cd /Volumne/workingdirectory > $ source ./build/envsetup.sh > $ gdb attach $pid > How can I repeat the same steps in emacs gdb? > After I type M-x gdb, i enter 'gdb attach $pid' , it just said 'gdb' > command not found . > My gdb location is setup by the script build/envsetup.sh. Who knows what your script does. Gdb in Emacs (GUD buffer) works almost the same as gdb from the command line. If you do 'gdb attach $pid' from the command line you get: Undefined command: "gdb". Try "help" just as you do in the GUD buffer. Try typing just "attach $pid". Here $pid must be a GDB convenience variable and not a shell variable. Why not read the Emacs and GDB info manuals which are readily available? -- Nick http://www.inet.net.nz/~nickrob ^ permalink raw reply [flat|nested] 5+ messages in thread
