macOS Monterey c++ #include error: no template named 'numeric_limits'

Question

I failed to run a c++ program with a simple line #include <cmath> in it. The error shows

% g++ cmath-bug.cpp
In file included from cmath-bug.cpp:1:
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1/cmath:642:26: error: no template named 'numeric_limits'
    bool _FloatBigger = (numeric_limits<_FloatT>::digits > numeric_limits<_IntT>::digits),
                         ^

......

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1/cmath:664:12: error: use of undeclared identifier '_Lim'
    return _Lim::max();

  } else if (__r <= _Lim::lowest()) {
                    ^
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1/cmath:666:12: error: use of undeclared identifier '_Lim'
    return _Lim::min();
           ^
11 errors generated.

I found some posts discussing similar problems but didn't get fixed.

My system version: macOS Monterey version 12.6

%xcode-select -p 
/Library/Developer/CommandLineTools

%g++ -Wp,-v -E -

Any comments are appreciated!

`sudo xcode-select -s /Applications/Xcode.app/Contents/Developer` might help. — 273K, Nov 07 '22 at 20:15
`/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/cmath:642:26: error: no template named 'numeric_limits'` The path changes but the errors are the same, I guess they use the same library. — Peter, Nov 07 '22 at 20:54
