Hello, I’m new to concrete and trying to run an example from the documentation where I can compile multiple functions using module. However I get the following error when I try to compile the code

Illegal instruction (core dumped)

I’m using virtual box 7.1.4 and Ubuntu OS 24.04.1. I’d appreciate any help. thanks

Hello @rraj , the error you got is an Illegal instruction. Concrete x86_64 releases are compiled for modern CPU so else the virtual box environment doesn’t support the instruction and/or your CPU.

Hi @yundsi, thanks for your response. Does that mean it’s not possible to use concrete in a virtual box environment?

Also, I installed concrete in a virtual environment (venv) as I was unable to install it globally. Could that affect the execution ?
