[llvm-dev] Using LLD to link against third-party libraries? How?

I mentioned the command I used in of my messages in this thread.  And of course I used clang++.exe to do it, not "LLVM".  I just meant I was using LLVM toolchain on the Developer Command Prompt for VS 2017.  Anyway, I'm trying again to build LLVM now.  I do have the MSVC compiler toolchain, but I want to try using the LLVM toolchain in Visual Studio since it's possible to do so.

I don't know what you mean by that.  "LLVM" isn't a command.  Can you
post the exact command you use to link?

I'm not at all familiar with Jinja2Cpp.  Is it possible it needs some
explicit template instantiations?

Are you saying you tried to build libc++ and couldn't?  I don't know
what C++ standard library clang uses by default on Windows.  If you
don't have a C++ standard library nothing will work.

I would concentrate on the standard library symbols first, because the
way that works is well-understood by everyone here.  Once you get that
working you may find a lot of the other stuff goes away.
