From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Andrew Udvare Date: Sat, 10 Oct 2026 03:19:17 -0400 Subject: [PATCH] Build std::filesystem into libc++.1.dylib macOS has shipped std::filesystem in libc++.1.dylib since 10.15, so binaries built for newer macOS import std::__1::__fs::filesystem::* from it and failed to load under Darling with "Symbol not found". Build src/filesystem/operations.cpp and directory_iterator.cpp, as C++17 like upstream does. int128_builtins.cpp is not needed, since Darling links compiler-rt.
