- a static inline function in a header is called through a pointer a small C file keeps (void *finch_inl_f = &f), built with the program's include folders and cached - --shared on macOS links with -undefined dynamic_lookup, as a .so does on Linux - "unable to find library -lx" (lld, MinGW) gives the library-not-found advice - the language server test shows the index records when alias completion fails Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016GzNP6r8dg6WDxUVZy8wjL
