I do not believe this is a Python 2 or 3 issue. I dug into the error recently and came to the conclusion you cannot embed the MacOS shipped Python any more when using Xcode as the tool chain. Apple has a file called: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/libpython2.7.tbd This file defines the clients that can be linked to this library and used and gdb is not one. This seems to limit the role and purpose of the OS built python and this is the first time I have encountered this. It is not clear to me if you can link to this library with a different linker so I am confused why this is has been done. I will raise a developers bug about this with Apple. MacOS installers are available for Python on python.org and given time I will look at adding support for these. I am wondering if we move to these versions of Python and away from the MacOS version? Python embedded in gdb is important when using C++. GCC ships with a set of pretty printers that aids using the `std` containers. I am in the process of looking at the auto-start support we need to have these automatically loaded and available.
