IP Example Design (DDR4 IP) Synth only Missing Libraries?

Generating an example design should create all the files you need. So you generate the example design which creates an ed_synth directory, you open the .qpf in there (the new example design project) and try to compile and you're getting this error?

That is very odd.

I'd trash the ed_synth directory and try to generate it again. That should not happen. The whole point of the example design is that it is a complete project that you generate and then compile.

Edit: or are you saying you did not switch to the new example design project but still trying to compile? Yeah, that won't work. You have to open the new generated project and then compile.
