Thank you, that gets me to the next step. Unfortunately, I don't get much 
further, getting these errors:

That sounds like you haven't completely set up your project correctly. Or not - 
QuickLook debugging can be flaky at times. What happens if you run it similarly 
from Terminal? Put some printfs or NSBeeps or something to signal that it has 
run in your plugin's functions. Look for printfs and other messages in Console.

Yes, I get similar messages when I run it from terminal:

I get this in the console:

}>

I put a printf in every routine in main.c, and none appear, so it's just never getting called. If I run nm on the executable and search for Quick, I get:

000000000011dbe0 t _AllocQuickLookGeneratorPluginType
000000000011dcb0 t _DeallocQuickLookGeneratorPluginType
000000000011df60 t _QuickLookGeneratorPluginAddRef
000000000011e010 t _QuickLookGeneratorPluginFactory
000000000011dfa0 t _QuickLookGeneratorPluginRelease
000000000011dd20 t _QuickLookGeneratorQueryInterface

So it appears to be there. I can't see what else to change in the plist. I tried qlmanage -r to reset the system, but it didn't help.
