Fixing GDB in Emacs on Mac OS 10.8 (Mountain Lion)

Table of Contents

Getting a new GDB

  • With the update to Mountain Lion, Emacs can no longer correctly interact with gdb. The easiest way to solve this is to install a newer version of GDB.
  • First, you must install HomeBrew (https://github.com/mxcl/homebrew). HomeBrew is a package manager for OSX that installs programs from source (similar to ports on BSD). You can install HomeBrew by running
    $ ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)"
  • Pay attention to what brew tells you. You may need to follow some additional instructions to get brew working. When in doubt, ask brew:
    $ brew doctor
  • Install a newer gdb:
    $ brew install https://raw.github.com/Homebrew/homebrew-dupes/master/gdb.rb
  • You're going to have to change your paths to make your machine prefer the newer gdb to the one that came preinstalled. Edit /etc/paths and make sure /usr/local/bin is at the top of the file (if not, remove it from elsewhere and put it on the first line)


Restart your computer. GDB should work properly now.
