My operating system is Ubuntu 24.04.

To ensure I had the most recent version of the R package “JuliaCall”, I installed “JuliaCall” from github as follows:

devtools::install\_github(“JuliaInterop/JuliaCall”)

The problem is that running julia\_setup() produces a segmentation fault. For example:

> library(JuliaCall)  
> julia\_setup(rebuild=TRUE)  
> Julia version 1.11.6 at location /home/robert/.julia/juliaup/julia-1.11.6+0.x64.linux.gnu/bin will be used.  
> Loading setup script for JuliaCall…  
> Finish loading setup script for JuliaCall.  
> Segmentation fault (core dumped)

Any help is much appreciated!
