Hello,
Could someone please tell me why LLVM and clang downloaded from here:
svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
svn co http://llvm.org/svn/llvm-project/cfe/trunk clang
and generated using cmake:
cmake -G “Visual Studio 15 2017” …/llvm
does not compile in Visual Studio?
I am using Batch Build in Visual Studio and I have selected only ALL_BUILD project to build as required in step 7 from here.

Thank you.
Last I’d heard, LLVM and clang didn’t compile with Visual Studio 2017. 2015 should work though.
It’s also helpful to include the error messages you’re getting, so that we can pinpoint any specific issues you might be running into.
Visual Studio 2017 works fine (I know because I personally made the changes to clang to get it working a few months ago 
Also, I use it every day.
But I don’t build from inside the IDE, only from Ninja.
But yea, seeing the error messages would help.
I am sending the errors:
