INSTALLATION:
- if not installed already, install
brew - if you have brew already on your system, you might want to update the brew installation, typing:
brew update. This will give you the latest installation recipes - install GDB:
brew install gdb. This will install the latest GDB.
CONFIGURATION:
If you try to start using the newly installed GDB in your terminal at once, you may get an error like this one:
If that’s the case, you should code-sign GDB. In order to do so, please follow the following steps.
As with GCC, the easiest way to install GDB is through Homebrew. In a Terminal window, run the command brew install gdb, and wait for it to complete. (As usual, it may ask for your password.) Now, we need to code-sign the GDB executable, so it will be allowed to control other processes, as necessary for a debugger.
- The question is “How can I install GDB on a Mac?” I’ve never tried - but if you’re using Xcode or the “command line development tools” on the Mac from Apple and want to use a command line debugger, then use “lldb” instead (llvm/clang seems to be t.
- Thank you for downloading Hopper GDB Server for Mac from our software portal. The download was scanned for viruses by our system. We also recommend you check the files before installation. The contents of the download are original and were not modified in any way. The version of the Mac application you are about to download is 1.8.
CODE-SIGNING GDB:
Clicking on Continue you will get a warning like “You are about to create a self-signed certificate.”, you can continue. You are now asked to set a validity period, in days; I just set 999 days (which appears to be the maximum value accepted, at least on Mavericks) so I don’t have to do it again in a short while. Then, for the purpose of this self-signed certificate made to run GDB on our system, you can skip all the other certificate settings, just clicking on “Continue” when asked, until your are asked to set the location
here, choose “System”, then click on “Create”.You might be asked for your password, and you will get your new certificate!
Now go to the Certificate Assintant window and look for your newly created certificate “gdb-cert”, then double-click on it. You will get the detailed info about the new certificate:
Click on “Trust”, and set the first setting to “Always Trust”
Close the Certificate Assistant window; you might be asked for your password to save the changes you made.
Now we want to kill the taskgated process, to be sure to pick the new certificate when code-signing:
Now we can code sign our GDB. To do that we open a shell, and we look for the GDB location:
then we can use this location to code-sign GDB, typing:
You might then be asked for your password.
If you get an error like this
then restarting your machine should fix the problem.
Now we can use the just installed gdb in our shell!
GDB: The GNU Project Debugger
What is GDB?
GDB, the GNU Project debugger, allows you to see what is going on`inside' another program while it executes -- or what another programwas doing at the moment it crashed.
GDB can do four main kinds of things (plus other things in supportof these) to help you catch bugs in the act:
- Start your program, specifying anything that might affect its behavior.
- Make your program stop on specified conditions.
- Examine what has happened, when your program has stopped.
- Change things in your program, so you can experiment withcorrecting the effects of one bug and go on to learn about another.

Those programs might be executing on the same machine as GDB (native),on another machine (remote), or on a simulator. GDB can run on mostpopular UNIX and Microsoft Windows variants, as well as on Mac OS X.What Languages does GDB Support?

The latest version of GDB, version 9.2, is available for download.
This is a minor corrective release over GDB 9.1, fixing the followingissues:
- PR tui/25586 (Resizing the source/disassembly or command window produces corrupted display)
- PR gdb/25650 (GDB can't 'printf' a convenience variable holding an inferior address)
- PR build/25981 (Use of short i386 register names breaks compilation on recent Solaris 11.4)
