Compilation fails due to missing file <clang-c/Index.h> but neither clang-c or Index.h exist

[MartimSalgado]

I have followed all the installation steps provided in "Build rtags" and also in Getting Started: Building and Running Clang (https://clang.llvm.org/get_started.html). Added clang and clang tools extra packages to the cmake statement. However, when I try to make in rtags, according to the instructions, I get the error message in the title.
I've deleted the CMakeCache.txt file and reinstalled llvm but nothing seems to work.

Running Ubuntu 20.04 LTS as a WSL for Windows 10

Thanks!

Hi, running into the same issue. Have you found any solution ?

Hi, unfortunately, no... Eventually gave up and found an alternative installation.
