Unfortunately the Qt frontend doesn't build either currently,

kblaschke commented 2 years ago

libprojectM's state is not always synced to the frontend's code, as we're still actively reworking the core library. I'm currently in the process of cleaning the library of code that shouldn't be part of it, e.g. the on-screen display, which was removed in the latest commit. Since it'd take a lot of effort to always keep all the frontends up to the development state of the library, this issue will remain for a while.

Until it is fixed, please just check out commit 62cecb36 of libprojectM, which will compile fine.

Okay, building this with 62cecb36 works.
