<div style="font-size:12pt">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

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

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

<br>
Are you saying you tried to build libc++ and couldn't? I don't know<br>
what C++ standard library clang uses by default on Windows. If you<br>
don't have a C++ standard library nothing will work.<br>
<br>
I would concentrate on the standard library symbols first, because the<br>
way that works is well-understood by everyone here. Once you get that<br>
working you may find a lot of the other stuff goes away.<br>
