INSTALLATION:

1. if not installed already, installbrew
2. 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
3. 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:

Installing G on a Mac. This section is intended to get you quickly started with C programming on your Mac. We'll be installing GCC 4.8.1 and GDB through a tool called Homebrew. If you want an additional guide on all of the following steps (except for installing GCC), the one by Moncef Belyamani is quite helpful. When you follow it, ignore.

Download Gdb Mac Software. Thread-GDB v.b.2.2.0 Extend the multi-thread capabilities of the gdb debugger. This targets POSIX threads implementations, although attempts to remain neutral with respect to the threads implementation. Creating a robust environment for thread debugging is the. $ cd gdb-7.11 gdb-7.11$./configure gdb-7.11$ make This step will take a bit of time. So you can sit back and have cup of coffee for a while. Once it is completed, you can locate gdb binary located at gdb-7.11/gdb/gdb. Step-4: Install GDB. $ make install By default this will install gdb binaries in /usr/local/bin and libs in /usr/local/lib. GDB Installation on Mac OS X. If you work on a Mac OS X 10.9 Mavericks or later, you will run into the problem of Eclipse refusing to interactively debug problems that otherwise build and run fine: An attempt to start a debugging session by selecting Run.

If that’s the case, you should code-sign GDB. In order to do so, please follow the following steps.

Osx Gdb

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 under High Sierra - no joy![message #1793946] Tue, 21 August 2018 01:20 Andrew Voelkel Messages: 17 Registered: September 2016 I have a C++ only Mac project and I'm sick of dealing with the poor C++ environment in Xcode. So I'd like to use Eclipse Photon. I've tried various recipes on Stack Overflow etc. to get native gdb to work with Mac OS High Sierra and Eclipse. After spending a couple hours still no joy. The variety of error messages is too great to enumerate. From the looks of the comments to the recipes I've found, this is far from a slam dunk. The problems seem to be: a) gdb 8.1 compatibility with Eclipse Photon. b) Big time code signing crapola with gdb and High Sierra. Should I just give up on this? I'm pretty damn frustrated at this point. It sure would be nice if I could just get a code signed version of gdb. I guess that most folks doing this sort of thing just use Xcode?

There is some discussion here: https://sourceware.org/bugzilla/show_bug.cgi?id=20266 Otherwise, you could also try the integration with LLDB, which I have been looking at improving, see https://wiki.eclipse.org/CDT/User/FAQ#How_do_I_get_the_LLDB_debugger.3F and following sections. It might not be a good solution for you yet but any feedback and bug reports are appreciated.

It seemed to work, but then I tried debugging some stuff which uses the STL container library, and it was pretty useless. I don't actually know that gdb would be much better. I've seen post about 'pretty printing' and python scripts, but that doesn't exactly sound like gdb is truly STL aware. For all its faults, Xcode actually handles this part 'OK'. It is a terrible C++ composition environment, but at least you can debug STL containers. I'm kind of shaking my head that STL container debugging isn't completely integrated and old hat in Eclipse by now. How long has STL been around? A long time. So at this point I use Eclipse for C++ composition and Xcode for debug. It seems pretty silly that is what I have to do, but there you have it. CLion is OK, but it isn't free and it has issues too. If I were in Windows, Visual Studio would 'just work'. But I gave up on Windows when Windows 8 came out and I'm not going back anytime soon.

I created a bug to track STL support https://bugs.eclipse.org/bugs/show_bug.cgi?id=539168 Most of the debug support in Eclipse was done for Linux and GNU toolchain (GCC, libstdc++ and GDB). With this combination, you can have good support for STL pretty printing and it should work out of the box. The way I understand it, GDB pretty printers are heavily tied to the standard library implementation details, so on macOS the pretty printing support would need to be implemented there for libc++ (I think that's the standard library being used?). I actually don't know how this works in Xcode but it sounds promising and maybe we can add it to lldb-mi support too. I do understand your pain, I've used Eclipse+Xcode combination and Eclipse+VisualStudio combination for a very long time. Pre-lldb in Xcode, it got to a point where Apple-gdb support was pretty on par (i.e. as bad) as Xcode. In the end, no one in the... thousands of users?... cares enough to make this work as well as on Linux.

With LLDB in either Xcode or CLion, you can dive down into STL containers interactively, looking at individual elements in the containers, and opening them up in a tree view pretty seamlessly. Does pretty printing let you do this? It kinda doesn't sound like it. I haven't been over to Windows to try this stuff on Visual Studio for a while, not since starting to use STL containers heavily. I'd be surprised if the experience were not at least as good as LLDB with Xcode or Clion, but I really don't know. I would think it would be a decent C++ composition tool also. But it isn't worth running Windows to do it. Not unless I'm hired to do a sizable C++ project on Windows, and I'm not holding my breath on that one. Without good debug support, using STL containers definitely loses a lot of its appeal! I should be thankful to have it, even if I have to use one IDE for composition and one for debug.

In LLVM for example, there are gdb pretty printers for a few base types, right in the repo.

I'm about to do a cross development project Mac Host / Linux Target. This should make life much better. It might also motivate me at some point to get gdb working on the Mac target. Too bad it doesn't work outta the box though!

No, I don't think it's supposed to work out of the box right now since there would need to be pretty printers installed along with libc++. They are often installed with libstdc++ which is more commonly used on Linux. I did find this however but never tried it: https://libcxx.llvm.org/docs/UsingLibcxx.html#gdb-pretty-printers-for-libc
