[issue46248] Compilation errors on macOS

Thanks for the report. Without more details, we can only guess at what you are trying to accomplish. I would assume it involves embedding Python in another library or application. If so, you should not be using LINKFORSHARED at all which is used to build Python itself (see, for example, Issue36508). Moreover, when embedding on macOS, we do not recommend trying to use the -framework argument to compile with or link to Python: it's too easy to get wrong. Instead, as shown in the use the "Extending and Embedding the Python Interpreter" section of the docset, use the output from the appropriate python3.x-config command, for example:

$ python3.10-config --cflags
-I/Library/Frameworks/Python.framework/Versions/3.10.1_11/include/python3.10 -I/Library/Frameworks/Python.framework/Versions/3.10.1_11/include/python3.10 -Wno-unused-result -Wsign-compare -Wunreachable-code -fno-common -dynamic -DNDEBUG -g -fwrapv -O3 -Wall -arch arm64 -arch x86_64 -g

$ python3.10-config --ldflags
-L/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/config-3.10-darwin -ldl -framework CoreFoundation
