How I get the same compile or cannot find X dependency errors as 20.10
I never tried compiling on 20.10, but are you compiling attract mode or attract mode plus? And did you install all the -dev prerequisite libraries? If compile fails for a missing dependency you should have an error message helping you find out what library you need. I have a long list of deps I install before compiling, probably it's more than necessary, btw it's this:
