After an update to Julia 1.4.2, my Fedora 32 desktop cannot start Julia anymore. The error message says:
> julia: error while loading shared libraries: libLLVM-8jl.so: cannot open shared object file: No such file or directory

It seems that your julia binary was compiled on a system with a different version of that library. If you’re using Fedora’s julia, then it’s a packaging issue.
You can find what libraries a binary is linked against by running `ldd julia`. On my system:
```
$ ldd julia
[...]
libLLVM-8jl.so => /home/mbaz/bin/julia-1.4.2/bin/./../lib/julia/libLLVM-8jl.so (0x00007f60b9c06000)
[...]
```
If I rename `libLLVM-8jl.so` I get:
```
$ ldd julia
[...]
libLLVM-8jl.so => not found
[...]
```

When I run `ldd julia`, I got:
`ldd: ./julia: No such file or directory`

You need to first `cd` to the directory where `julia` is, or provide the path to `ldd`, for example `ldd /usr/bin/julia`.
You can find where your `julia` binary lives by running `which julia`.

I see:
`libLLVM-8jl.so => not found`

Then there’s your problem: your `julia` binary was compiled in a system with that library, but it’s not present in your system.
If you installed julia via Fedora’s packaging system, and the problem remains after a full system update, then the problem is with Fedora’s julia package.

That is what I thought. I just updated my system and the problem should be on Fedora’s side.
