ld: library not found for -lstdc++

When I try to compile, I get the error
```
/usr/local/Cellar/go/1.16.3/libexec/pkg/tool/darwin_amd64/link: running clang++ failed: exit status 1
clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of OS X 10.9 [-Wdeprecated]
ld: library not found for -lstdc++
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
It seems like https://github.com/andlabs/ui/issues/306 is similar, although the error message is slightly different.
How do I fix this?
