I’m reanimating old code.

This worked 5 years ago on whatever the latest macOS version was back then.

However now pip install pysas fails.

clang: error: invalid version number in 'MACOSX_DEPLOYMENT_TARGET=11.5'

Following instructions from Big Sur clang “invalid version” error due to MACOSX_DEPLOYMENT_TARGET

> sudo rm -rf /Library/Developer/CommandLineTools
> softwareupdate --all --install --force
> sudo xcode-select --install

… I get a much bigger error-dump, including hundreds of lines such as:

      using ::islessgreater;
            ~~^    /Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk/usr/include/c++/v1/cmath:332:9: error: no member named 'isunordered' in the global namespace

I’ve filed an issue: https://github.com/shunsukeaihara/pysas/issues/3

Asking here as the project doesn’t seem to be actively maintained, and I suspect the issue is to do with getting my compiler tools in order on my macOS.

If it helps:

> xcrun --show-sdk-path
/Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk

Can anyone help disentangle this?
