<div dir="ltr">I am evidently one of those rare people successfully building LLVM v7 inside VS 2017 and targeting WebAssembly. Unlike Osman, I build the 32-bit version, but I suspect I would have no significant trouble switching to building the 64-bit version.
<div><br>
</div>
<div>I use CMake-Gui vs. Osman using Cmake on the command line. This allows me to use the mouse to select the CLANG_BUILD_TOOLS and LLD_BUILD_TOOLS options which are also needed to build those tools along with the rest of LLVM. I do this after the Configure
step and before the Generate step.</div>
<div><br>
</div>
<div>When that is done, I double click on the generated LLVM.sln file to fire up Visual Studio. I then right-click on BUILD_ALL to build LLVM, followed by right-clicking on INSTALL to finish the process a few hours later.</div>
<div><br>
</div>
<div>That said, I looked at Osman's log and saw the build was struggling to locate various include files, which seems a very basic error suggesting something fundamentally is amiss with how the build is locating LLVM source files. I know too little about Osman's
set up and LLVM's CMake process to hazard a guess as to what might be causing that.</div>

<div dir="ltr">I think most people are using ninja to do the build. You can still use the Visual Studio generator for the IDE experience while doing build from ninja. I know there are a couple of people who build from inside of Visual Studio, but it's a pretty
small number, and I don't think they are targeting WebAssembly.</div>
