lldb KDK vs python

which python

--version

% sw_vers
ProductName:    Mac OS X
ProductVersion: 10.15.4
BuildVersion:   19E266
% which python
/usr/bin/python
% ls -l /usr/bin/python
lrwxr-xr-x  1 root  wheel  75 Oct  8  2019 /usr/bin/python -> ../../System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7
% python --version
Python 2.7.16

Judging by the error, my guess is that someone has changed the default

python

It is stubborn alright.

It seems rather determined to run python3:

# /usr/bin/lldb -P

/Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework/Resources/Python3

# /usr/bin/lldb --version

lldb-1100.0.30.12

Apple Swift version 5.1.3 (swiftlang-1100.0.282.1 clang-1100.0.33.15)

However:

# /Library/Developer/CommandLineTools/usr/bin/lldb -P

/Library/Developer/CommandLineTools/Library/PrivateFrameworks/LLDB.framework/Resources/Python

# /Library/Developer/CommandLineTools/usr/bin/lldb --version

lldb-1001.0.13.3

Swift-5.0

# /Library/Developer/CommandLineTools/usr/bin/lldb /Library/Developer/KDKs/KDK_10.14.6_18G2016.kdk/System/Library/Kernels/kernel

(lldb) target create "/Library/Developer/KDKs/KDK_10.14.6_18G2016.kdk/System/Library/Kernels/kernel"

So I have a way to keep running KDKs.. Sorry for the noise.

Ah, just noticed you’re using a 10.14.x KDK. What do you see if you try a 10.15.x KDK?

/usr/bin/lldb fail, but with additional message

WARNING! Python version 3 is not supported for xnu lldbmacros.

Please restart your debugging session with the following workaround

defaults write com.apple.dt.lldb DefaultPythonVersion 2

So that is all the clues one needs maybe, using the /Library/Developer/CommandLineTools/usr/bin/lldb

everything works like before.
