[llvm-dev] clang build failures using Visual Studio

[Shoaib Meenai via llvm-dev]

We discussed this on IRC. As far as I know, Visual Studio 2017 isn't fully supported yet (it's being worked on), but VS 2015 should work.

Subject: [llvm-dev] clang build failures using Visual Studio

Anyone run into this before?
I'm trying to get a Windows native build using Visual Studio of LLVM, Clang, and LLD 4.0.0. So far LLVM built successfully, but I'm getting these cryptic error messages when building Clang:
