Fatal error LNK1201

I’ve seen others ask this question, but haven’t seen an answer. Up until recently, my project has always built fine on Windows (it still builds fine on my Mac, but I’m trying to build a Windows version as well).

Now, however, I can’t link, and get this error:
fatal error LNK1201

Just before this, I was getting a link error saying there were too many files, so I did a clean. I’ll try cleaning again …

This is on cocos2dx 3.13
