ubsan missing

I googled and found other people talking about this but can’t find any solution

Hi,

Do you build llvm with -DLLVM_ENABLE_PROJECTS=“compiler-rt;clang;…”?

Sounds like you don’t build the needed runtime.

Regards,

Miklos

I built using
https://clang.llvm.org/get_started.html#build

under the heading “on unix like systems”
