[llvm-dev] Using LLD to link against third-party libraries? How? (original) (raw)

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?

The ones I want to fix first are the ones from Boost and Jinja2Cpp. I saw some from those as well.

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

If there any standard library ones missing, could it be because I couldn't get it to build libcxx? I did try to include that, but it seems to be missing. What should I do?

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.
