The same happens on julia 1.0.x. Any ideas where the /julia/sys.so: failed to map segment from shared object comes from?

It works for me:

(v1.2) pkg> add NonlinearEigenproblems
 ...

julia> using NonlinearEigenproblems

Your dynamic linker failed to load sys.so. Does your user have execution permission for that shared library?

See here for more info:
https://unix.stackexchange.com/questions/496292/what-does-a-failed-to-map-segment-from-shared-object-error-mean

I’m not familiar with Raspberry Pis, but this link suggests that only root and the pi user have execution permissions in that directory by default:

Thanks! I got the same error when I run julia as root or pi. I also tried running on the /usr/local/bin filesystem. Same results. This does not exclude an execution permission problem.

Eventually I tried a system upgrade raspian buster to get julia 1.0. It crashed my system completely, so I need some time to fix it before following up on this.

A fresh install with Raspian version buster, and julia 1.0.3 seems to have solved the problem. Thanks again.
