This is how I easily fixed the issue. Update: based on feedback received and yet to be verified, it seems that this solution works with macOS Sierra 10.12 but not with macOS Sierra 10.12.2 See video instructions here. Quit gdb; Using your text editor e.g. Sublime Text. Just tried out Apple's new beta of the next version of OS X, namely macOS 10.12 Sierra. A freshly compiled gdb 7.11.1 is not capable of debugging anything I've tried yet, it always fails with: During startup program terminated with signal SIGTRAP, Trace/breakpoint trap. This is an issue specific to macOS 10.12 beta, the same gdb works fine. May 07, 2019 untar gdb-weekly-8.2.6.tar.xz gdb-8.2.6./configure make make install Important (I think) I have GCC 8 setup by default via Homebrew brew install gcc. Note: - lldb is used in mac as gdb. The problem is that you are not logged in as a root user (which you don't want). You need to create a certificate for gdb to be allowed access.

GDB under High Sierra - no joy![message #1793946]

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?

I was able to make GDB 8.0.1 work OK on High Sierra, compiling it from source and following the instructions here https://sourceware.org/gdb/wiki/BuildingOnDarwin. 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.

I tried lldb-mi. 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.

You bring up a good point about STL support. 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.

I'm curious about what this 'pretty printing' buys you. 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.

Yes, it lets you do that.
