I'm running into problems debugging c++ under emacs. When I start the debugging command:

M-xgdb --annotate=3 myprogram

The gdb shell does not prompt. Instead it stuck after showing (gdb) Current directory is ~/programs/small/ as pasted below. I can't type any debug command then... However the status bar shows no error messages. Does any body know how to fix it? Thank you!

Reset to default

I had a problem like this once caused by binding some keys in .inputrc. If you're not sure whether you have bound keys in this way you probably haven't, but to test it you can run emacs as

INPUTRC= emacs &

and see if that fixes it.

Perhaps more likely is that you are using the new mi interface to Emacs. In Emacs 24 (not yet released, but available in snapshots) this is the default and gdb --annotate=3 is no longer "the right thing." For the new interface you want gdb -i mi.

wow, "INPUTRC= emacs" fixed it ! You might want to point out that you do want the space after the '=' sign and you don't need the trailing "&"
