macOS g++ no longer usable after updating Xcode

After updating to Xcode 15, I cannot use g++.

I downgraded to Xcode 14.3.1 and "brew reinstall gcc", result was not changed.

When I use g++ xxx.cpp the below error is displayed.

-macosx_version_min has been renamed to -macos_version_min

    I temporary fixed with below flow.

    $ brew install gcc

    This results in gcc with apple clang. As a result, following command worked well.

    $ g++ main.cpp -std=c++11

    I also faced a similar issue, updating gcc works pretty well.

    brew install gcc

    This command will install, or update the current version on GCC accordingly, you don’t need to delete the current version and install the new one.
    I am currently using an M1 MacBook, and it works pretty well!
