Yes, I suspect this is a "user-mode only build" specific failure (you may need --disable-system --disable-tools to see it). meson.build only puts authz into trace_events_subdirs "if have_block" (which is to say "if have_system or have_tools"). However the bit of meson.build that says "subdir('authz') does not have the same condition on it -- it's just been put in the list without any condition on it. So I think that in a build-only-user-emulators config meson will not generate trace events for the subdirectory but will try to build it, which falls over. Contrast 'block', 'nbd', 'scsi', which are all guarded by 'if have_block' for their subdir() lines, to match the guard on the trace_events_subdirs. OTOH 'io' is also mismatched-guards... Why this only shows up with your pullreq I have no idea. thanks -- PMM

Before you added your test, meson had no need to compile any of the object files in 'migration', so it didn't. Now you tell meson to build a new executable, and it says "OK, I must build these object files". Only it turns out that they won't actually compile in this config, so you get an error. The same issue can happen in good old Make :-) thanks -- PMM
