I’m kind of suspicious that this might be a corrupted cache (`.ji` files are caches for packages to speed up loading time). This is a long shot, but could you try:
```julia
rm.(
[
"/home/marongiuluigi/.julia/compiled/v1.4/Sundials/",
"/home/marongiuluigi/.julia/compiled/v1.4/DifferentialEquations/",
"/home/marongiuluigi/.julia/compiled/v1.4/BoundaryValueDiffEq/"
];
recursive = true, force = true
)
```
to nuke your cache files, then `using DifferentialEquations` and sit back for a cup of tea (it might take a while to precompile).

even nuking did not work:

Do you have any chance to try this with a different Julia version, for example v1.3.1?

In all other machines I upgraded (ubuntu and mint) the re-compiling worked thus it is OK. It was working on chromebook with 1.3…

I’m lost in your all previous attempts so far, fave you tried already to start from scratch, i.e. rename your `~/.julia` directory so that you have a completely clean environment?

nothing even like this. I give up: I simply won’t use D.Eq on a chromebook. Thank you for your persistance and help.

I can run DifferentialEquations.jl without problems with Julia 1.4.1 on my chrombook (also with Intel CPU)…
Some things to try:
- Start Julia in a new directory, then `]activate .` before adding DifferentialEquation
- Rename `~/.julia` to some temporary name before starting Julia, to try with a clean environment.
- Install Docker, then `docker run -it julia` and see if you can use DifferentialEquation there.

Just use OrdinaryDiffEq.jl directly if you need the ODE solvers. Unless you’re specificially solving BVPs this is an easy workaround. But indeed this is extremely odd.

Could you try and generate an rr trace?
```julia
using Pkg; Pkg.add("BugReporting")
using BugReporting
BugReporting.make_interactive_report("rr")
using DifferentialEquations
```

looks like OrdinaryDiffEq worked:
```julia

I am here:
```julia
julia> BugReporting.make_interactive_report("rr")
rr needs /proc/sys/kernel/perf_event_paranoid <= 1, but it is 2.
Change it to 1, or use 'rr record -n' (slow).
Consider putting 'kernel.perf_event_paranoid = 1' in /etc/sysctl.conf

if you do `using DifferentialEquations` after that it should upload a report, and then @Keno knows what to do about it and I need to learn.
