Automake dependency tracking information is computed as a side effect
of compilation. So, the first time things are compiled, it has no way
of knowing about dependencies on generated files.
BUILT_SOURCES is a hack to get around this. It basically inserts a
'make $(BUILT_SOURCES)' before targets like 'all'. (It would be nice
to have per-{executable,library} BUILT_SOURCES...)
I didn't look into this too deeply but I would guess that it is more
make-related than automake-related. You can add rules to the
Makefile.am to help with debugging, eg:
hack:
$(MAKE) $(BUILT_SOURCES)
Then in theory 'make hack' should reproduce the problem you're seeing.
If that doesn't happen then something weird and perhaps
automake-related is going on. If it does happen, you can try plain
old Makefile debugging with 'make -d'.
