This seems to be a problem that has been popping up quite often with Big Sur. The mentioned solutions for checking the symbolic link for the MacOS.sdk don't seem to solve my problem. I'm trying to build a c++ module for python using a setup.py script. Running in verbose my command line shows:
running build
running build_ext
building 'pparser' extension
Compiling with an SDK that doesn't seem to exist: /Library/Developer/CommandLineTools/SDKs/MacOSX11.3.sdk
Please check your Xcode installation

Yet my directory shows the correct symbolic links:
```~/Programming/git/Jupyter/Parsers % ls -al /Library/Developer/CommandLineTools/SDKs main

drwxr-xr-x 7 root wheel 224 Jul 12 19:31 .

lrwxr-xr-x 1 root wheel 14 Jul 12 19:30 MacOSX11.sdk -> MacOSX11.3.sdk
I'm trying to force some of the settings in the setup script:
from distutils.core import setup, Extension
class custom_build_ext(build_ext):
def build_extensions(self):
# Override the compiler executables. Importantly, this
# removes the "default" compiler flags that would
# otherwise get passed on to to the compiler, i.e.,
# distutils.sysconfig.get_var("CFLAGS").
self.compiler.set_executable("compiler_so", "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++")
self.compiler.set_executable("compiler_cxx", "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++")
self.compiler.set_executable("linker_so", "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++")
build_ext.build_extensions(self)
[
setup(name='pparser', version='1.0', \
ext_modules=[Extension('pparser',
['pparser.cpp'],
extra_compile_args = ["-Wno-nullability-completeness",
"-Wno-undef-prefix",
"-I/usr/local/opt/flex/include",
"-I/usr/local/opt/bison/include",
"-std=gnu++14",
"-isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX11.3.sdk",
"--verbose"],
extra_link_args=["-flat_namespace"])])
]
I'm lost on what to try next.
