O2 build error: LLVMAlt missing for package arrow

O²
1

Dear experts,

I’m trying to build O2 on Ubuntu 20.04 LTS. I followed all steps on the tutorial. Some packages caused problems, but I have been able to solve them so far (e.g. manually setting python version used).
Now the construction of the package arrow fails and I get nowhere. In the log (which I have attached) it says that the package LLVMAlt is missing. But I can’t find any information about the error and the package in general. Quoting log lines 112-124:

CMake Error at cmake_modules/FindLLVMAlt.cmake:27 (find_package):

Do you have any idea?

Cheers,
Tim

Dear all

I am getting the same error today in macOS 10.15.7 …
Is there a known solution to this?

Note: last time I compile all O2, at the end of August, I did not have this problem …
any help is welcomed :slight_smile:

have a nice day
