I've recompiled my MacOS program for GCC (GNU C++17) and linked with libstdc++ to be compatible with the default build of Boost.  Your suggestion WAS the solution to my reported slew of error messages.  Thanks!

QUESTION 1:  But for building a standard MacOS or iPhone/iPad app, shouldn't I be building both my app and Boost for clang, so I can link with libc++?

When I looked at the list of toolsets in the "getting started with unix variants", included with the 1_85_0 .zip package, there was no listing for toolset=clang or toolset=clang-darwin.  Nor is there any mention of clang on:

https://www.boost.org/doc/libs/1_85_0/more/getting_started/unix-variants.html

QUESTION 2:  So what is the proper toolset / build instructions to build for MacOS using the clang C++17 compiler?
