Fail to build on ArchLinux

I'm trying to build on ArchLinux and get (msg below). Any idea how to handle this?

I am getting the same error trying to build in Elementary OS 5.0 Juno.

Looks like parenthesis around a token are used for casting variables to another type (like C). If you remove the parenthesis from those lines it seems to compile. I'll work on a pull request, despite the fact that the project seems to be unmaintained.
