[package] boost/1.75.0: Undefined symbols for boost_fiber with option boost:shared=True

[DominikDeak]

When I try building shared libraries for boost via the Xcode toolchain, I get undefined symbols errors for boost_fiber library. See more verbose log snippets at the bottom of this post.

      Undefined symbols for architecture x86_64:
        "boost::fibers::context::active()", referenced from:
            boost::fibers::numa::algo::work_stealing::pick_next() in work_stealing.o
        "boost::fibers::context::attach(boost::fibers::context*)", referenced from:
            boost::fibers::numa::algo::work_stealing::pick_next() in work_stealing.o
        "boost::fibers::context::detach()", referenced from:
            boost::fibers::numa::algo::work_stealing::awakened(boost::fibers::context*) in work_stealing.o
      ld: symbol(s) not found for architecture x86_64
      clang: error: linker command failed with exit code 1 (use -v to see invocation)
