The version of gdb on Mac OS X as part of Xcode is very old and will not work with godbg. Make sure to add the “C:\MinGW\bin” directory to your PATH so that godbg can pick it up. Once MingW is installed, run the “MinGW Installer” to add the mingw32-gdb package (under “All Packages”).

To install the MinGW version, visit to download and install the tool suite (mingw-get-setup.exe). Gdb is available on Windows in either MinGW or Cygwin. Newer versions of Linux will often come with these versions of gdb but Windows and Mac need a little extra setup. This version of godbg should work with gdb versions 7.5 and 7.6. Godbg uses the gdb MI (Machine Interface) to debug your application.
Gdb requires special privileges to access Mach ports. Note that when you install gdb with Homebrew, the following is shown: => Caveats I ended up doing brew reinstall gdb, deleting all the certificates I had created, rebooting and then very carefully following the procedure again. I can't really believe how often disabling SIP is suggested as a solution to this problem - if you get desperate I'd sooner advise running sudo gdb (have backups!) than disabling SIP.įor me, the problem was that I repeatedly messed up one or more steps in the procedure. Yes, code signing should work is a substantially better alternative to disabling SIP. So I went through the instructions (except for the ones for Snow Leopard), and it still doesn't work! Anyone knows how I can make it work? So I googled a bit about codesigning, and found this. (please check gdb is codesigned - see taskgated(8)) Unable to find Mach task port for process-id 42492: (os/kern) failure (0x5).

So I installed GDB (The GNU Debugger) for following among a book I am currently reading ("Hacking: The Art of Exploitation"), which only explains how to use GDB, so I can't use LLDB. First I should note that I'm using macOS Sierra (version 10.12 beta 16A238m), but I don't think it's that different than El Capitan in this certain situation (but I guess you know more than I do about that, or I wouldn't be here right now asking this question).
