Hi Geoff, Unfortunately, the binary_function has been removed in recent versions of the Clang compiler. As a workaround, you can change `binary_function` in line 48 of src/sorting.h to `std::__binary_function`. That fixes the compilation with Clang.
Alternatively, you can use gcc-13 from homebrew as a compiler which still works
without modifying the code.
Cheers,
Oliver
