I've reproduced it with an executable that just includes <boost/parser/parser.hpp> and a trivial main.

I think you're hitting these:

• C++20 ranges/views are broken, via std::ranges::ref_view - iterator_concepts.h:980:13: error: no matching function for call to '__begin' llvm/llvm-project#52696
• [concepts] deferred substitution into requirements of class template members not implemented llvm/llvm-project#44178

Yep. Looks like it. I guess I'll need to disable the use of concepts in Clang < 16.
