Oddly a file containing a package (package keyword) is compiled perfectly.

Yosys does not support SystemVerilog imports at the moment, and as far as I know there are no plans to. You can use sv2v, or purchase a commercial license which lets you use the Verific frontend that has SV support.

Ok I used sv2v and it worked. Thanks!
