[llvm-dev] FW: Successfully build libstdc++ for wasm32-wasi
Hello clang and llvm devs. Can you enable -stdlib=libstdc++ for wasm32-wasi? I have successfully built libstdc++ with clang, targeting wasm32-wasi. Problem is clang does not support this for that target. Options like -nostdinc++ will end up conflict with -lc++abi since clang always adds -lc++abi to the compilation command. I know GCC itself does not support webassembly, but Libstdc++ can be built.

It always adds -lc++abi toggle. Is that possible to disable this and use -lsupc++? That seems like a question about using clang, so off topic here, but I would try -nostdlib -lsupc++ -------------- next part -------------- An HTML attachment was scrubbed...
