OK, I must admit to be stuck here. How can I know what objects files
are expected to be compiled from, say, a bar.c file, in turn generated
from a bar.l file?
Or (e.g.) how can I distinguish the following situation:
foo_SOURCES = bar.l
(where bar.c is generated from bar.l, bar.o is generated from bar.c,
and no explicit dependency rule is generated), from the following
situation:
foo_SOURCES = bar.l
foo_CFLAGS = $(AM_CFLAGS)
(where bar.c is generated from bar.l, and foo-bar.o is generated from
bar.c, with an explicit dependency rule of foo-bar.o from bar.c)?
Thanks,
Stefano
