[llvm-dev] Ld64.lld cannot find Foundation framework

[Edmund Furse via llvm-dev]

Thanks for your reply.  Two questions:
1). Will ld64.lld be fixed in LLVM v11.0 and when is this likely to be?
2). You mention Apple’s linker, by which I assume you mean GNU’s ld.
	Is it possible to get a binary version of ld (preferably that does not use other things from /usr/bin)?

Thanks
