problems with libclang

[Giuseppe Barbieri]

Hi,

I'm giving a shot at building this myself, but I'm having issue with the
clang step

Recalling Maurizio's previous suggestion about using pre-compiled llvm
instead of the distro ones (btw is this still recommended?), I downloaded
from

https://releases.llvm.org/download.html

the llvm 9.0.0, by using

Ubuntu 19.04
<https://releases.llvm.org/9.0.0/clang+llvm-9.0.0-x86_64-pc-linux-gnu.tar.xz>
(since I'm on Ubuntu 21.04)

However, it still complains:

Any idea why?

Thanks in advance
Giuseppe
