Compiling Error on a Manjaro-Machine

[Flackermann]

I encounter the following issue when trying to compile the cloned repository. Since I am not that experienced with this stuff, I hope to get some help here. Thanks in advance!

I think you're trying to compile Avogadro 1.2 with Open Babel 3.x, which broke backward compatibility.
