Hi, I'm trying to build and getting this error:

Any idea what to do about it?

Thank you

You've hit a GCC bug, which is surprising. I'd encourage you search to see if this ug has already been reported, if not it would be good to report it.

In the meantime, perhaps try a different version of GCC or try building with Clang.

What disto are you using, out of curiosity?

Thank you, I'll try to figure out how to change the gcc version or how to use clang. I'm using Ubuntu Server 22.04.4

Strange, as it's a mainstream distro. I am using gcc (GCC) 11.4.1 20230605, but on Rocky linux with no issues, but I've also compiled with 22.04.

Maybe try re-installing the development package just in case

Hi, I think the problem was that I was missing some deps... Installed sudo apt install -y build-essential cmake libgmp-dev libnuma-dev then it worked!
