Hi guys,
I'm getting the following installation error:

I encountered the same problem as you, there are lots of warnings and errors shown in the terminal, maybe it's caused by the mismatch of gcc/g++ version? I don't know which version the author use.
Hi, I'm encountering the same error. Has anyone found a fix yet?
