I am trying to install the `HomotopyContinuation.jl` package, but I get an error when I try to precompile this package. This is because the following packages throw an error when precomiling:  
✗ MPFR\_jll  
✗ FLINT\_jll  
✗ MPC\_jll  
✗ Arb\_jll  
✗ SymEngine\_jll  
✗ Arblib  
I installed julia on fedora using dnf. The entire error log is given below. What would you guys recommend I try next?

```bash
julia> import Pkg; Pkg.precompile()
Precompiling project...
  ✗ MPFR_jll
  ✗ FLINT_jll
  ✗ MPC_jll
  ✗ Arb_jll
  ✗ SymEngine_jll
  ✗ Arblib
  ✗ HomotopyContinuation
  0 dependencies successfully precompiled in 8 seconds. 153 already precompiled.

I’d recommend uninstalling Julia and reinstalling it using either one of [the official binaries](https://julialang.org/downloads/#supported_platforms) or perhaps better using [juliaup](https://julialang.org/downloads/#install_julia) by copying this incantation into a terminal of your choice:

```shell
$ curl -fsSL https://install.julialang.org | sh

```

Usually package maintainer replace shared libraries used by Julia with the standard ones of their distribution which will cause compilation failures like the one you are seeing.
