Hmm, this is pretty much what I did. I have

foo_SOURCES = foo/foo.c foo/foo_parse.y foo/foo_scan.l foo/foo_state.c

in $(top_srcdir)/Makefile.am. I moved foo_parse.[ch], foo_scan.c from
$(top_builddir) to $(top_srcdir)/foo. When I type "make", the files are
generated in $(top_builddir); the files in $(top_srcdir)/foo are not
updated.

Moreover, "make distclean" in $(top_builddir) doesn't delete the
generated files.

I've also tried:

* Copying ylwrap to $(top_srcdir).

* Creating foo/Makefile.am, updating AC_CONFIG_FILES and rebuilding.

Neither one helped.

I assume the difference shouldn't be the fact that you generate C++
source. What else could affect the behavior? Which version of automake
do you have? Do you have ylwrap in $(top_srcdir)?

With kind regards,
